The buyer is Korea ESS Power Co., Ltd. headquartered in Seoul, South Korea, a specialized and sophisticated listed enterprise focusing on high-end industrial and commercial energy storage and hybrid passenger vehicle supporting square lithium batteries combining lithium iron phosphate and medium-nickel ternary systems. Its products are mass-supplied to vehicle energy storage modules of Hyundai and Kia, with long-term original procurement of lithium battery-specific PVDF resins from Solvay Solef and Wu Yu. It only purchases mid-to-high-end lithium-grade PVDF for power battery binders, completely excluding low-grade general PVDF raw materials for pipe extrusion, anti-corrosion coatings and general injection molding applications. Its products comply with three layers of access standards including South Korea KC battery safety certification, REACH-SVHC and the EU New Battery Regulation, with an annual global PVDF procurement volume exceeding 120 tons, ranking as a high-quality mid-to-high-end terminal buyer in the fluororesin subdivision sector.
In 2025, affected by tight domestic fluorochemical production capacity in Japan and South Korea, extended ocean transportation cycles of imported PVDF exceeding 70 days and continuous 27% hikes in global raw material quotations, the client launched a screening process for localized alternative PVDF supply chains. Recommended by the Korea Chemical Raw Materials Chamber of Commerce, the client connected with HiSiaddi New Materials Foreign Trade based in Shanghai, planning initial small-batch trial procurement of 2.2 tons of lithium PVDF and signing a long-term annual procurement framework of 35 tons after production line verification.
The client previously independently contacted five domestic leading PVDF manufacturers to request samples one by one, yet encountered common industry issues: each manufacturer only promoted its own product advantages without belittling competing brands, but deliberately avoided highlighting competitors’ strengths and only pushed its own grades. Lacking systematic knowledge of domestic PVDF brands, the client failed to horizontally benchmark performance differences, matching application scenarios among five mainstream mid-to-high-end brands including Dongyue, Sinochem Lantian, Fluorine, Juhua and Shanghai 3F. After receiving six samples with scattered parameter indicators and inconsistent key indicator labeling standards from different manufacturers, three months of independent screening failed to lock matching models, and successive bench-scale trials of samples encountered abnormal slurry viscosity and unqualified electrode peel strength, stalling the brand selection work. The client fully entrusted HiSiaddi to rely on domestic fluorochemical resources to objectively analyze mainstream brands horizontally and screen optimal brands and product models.
South Korean R&D and procurement teams have long used imported PVDF from Europe, America and Japan, with no understanding of industrial chain layouts, production processes (suspension/emulsion polymerization) and raw material self-sufficiency capabilities of five domestic leading enterprises including Dongyue Group, Sinochem Lantian, Fluorine, Juhua and Shanghai 3F. Some manufacturers possess self-produced integrated R142b monomer supporting capacity, while others purchase external monomer raw materials. The two models differ significantly in batch stability, impurity control and price fluctuation margins. Sales personnel of all manufacturers remained silent about industrial chain weaknesses, leaving the client unable to distinguish raw material grades.
Sales staff of all five manufacturers prioritized promoting their own hot-selling grades: Dongyue pushed DF207 and DF209 homopolymer grades with high adaptability to lithium iron phosphate; Sinochem Lantian promoted self-developed lithium battery-specific copolymer powder; Fluorine focused on Zhefluor FL2052 and FL2100; Juhua pushed suspension-process lithium battery powder; Shanghai 3F promoted LFP-specific homopolymer PVDF. All avoided discussing competitors’ advantages in copolymer modification, particle size, molecular weight and electrolyte compatibility. The client received five sets of differentiated product specifications with inconsistent labeling standards for key indicators, unable to match its dual-system production conditions combining NCM523 medium-nickel ternary and LFP lithium iron phosphate.
A single domestic leading brand maintains more than five mid-to-high-end lithium battery grades divided into homopolymer and copolymer categories, separately adapted to lithium iron phosphate and medium/high-nickel ternary systems. The client’s production lines handle both energy storage lithium iron phosphate and vehicle medium-nickel ternary cells, requiring one universal grade plus two segmented dedicated PVDF grades. A single factory cannot simultaneously deliver optimal solutions for dual systems, and independent selection easily leads to mismatched grades and reduced production line yields.
All above difficulties focus on refined brand selection of mid-to-high-end lithium battery PVDF. Low-grade PVDF for coatings and pipes only needs to meet basic acid and alkali resistance without distinguishing polymerization processes, molecular weight ranges or electrolyte compatibility indicators, eliminating such multi-dimensional selection challenges.
HiSiaddi set up a technical + foreign trade selection team specializing in fluororesins. Benchmarked against parameter standards of two imported benchmark products Solvay 5130 and Arkema V900, the team discarded one-sided marketing rhetoric from manufacturers, objectively disassembled full-dimensional advantages and disadvantages of five domestic mid-to-high-end leading brands including Dongyue Group, Sinochem Lantian, Fluorine, Zhejiang Juhua and Shanghai 3F from five dimensions: industrial chain, production processes, mainstream grades, matching application scenarios and weaknesses, and sorted bilingual Chinese-English comparison data tables synchronized item by item for confirmation with the Korean R&D department:
1. Dongyue Group (Shandong): A long-established listed fluorochemical enterprise in China with sufficient emulsion process production capacity. Mature DF207 and DF209 homopolymer grades deliver high adaptability to lithium iron phosphate, with advantages of large mass production scale and ample spot inventory; Weaknesses include weak suspension copolymer process technology, scarce high-nickel ternary matching grades, medium monomer self-sufficiency rate and insufficient flexibility for customized modification.
2. Sinochem Lantian (Zhejiang): A central state-owned integrated factory under Sinochem Group with self-owned R142b monomer production capacity and complete dual production lines for emulsion and suspension processes. Self-developed copolymer modification technology delivers top-tier control of metal ion impurities, suitable for medium and high-nickel ternary systems; Weaknesses include higher quotations for general lithium iron phosphate grades and slightly longer sample scheduling cycles for small batches.
3. Fluorine Chemical (Zhejiang): A private domestic benchmark leader in copolymer PVDF with complete Zhefluor full-series lithium battery grades. Three core models – universal copolymer FL2052, high-nickel dedicated FL2100 and lithium iron phosphate dedicated FL2032 – benchmark Solvay systems with mature suspension and emulsion processes and flexible modification capabilities; Weaknesses include external procurement of core VDF monomers and slightly larger raw material cost fluctuations during peak demand seasons.
4. Zhejiang Juhua: A long-established state-owned fluorochemical enterprise in China with self-owned fluorine raw material industrial chains. Suspension-process products feature high crystallinity and excellent peel strength, dominating the energy storage lithium iron phosphate market; Weaknesses include fewer copolymer modified grade categories and limited product options for ternary system matching.
5. Shanghai 3F: Mature emulsion homopolymer processes deliver outstanding cost performance, deeply cultivated in the lithium iron phosphate binder track; Weaknesses include low R&D investment in high-end copolymer products, lack of mainstream grades adapted to medium-nickel ternary systems and relatively single product categories.
① FL2052 (VDF-HFP copolymer universal PVDF): A universal grade compatible with both NCM523 medium-nickel ternary and LFP lithium iron phosphate, with 3.2% HFP copolymer ratio, excellent flexibility and electrolyte swelling resistance, matching the client’s main universal production line to replace original imported Solvay Solef 5130 materials. ② FL2032 (homopolymer modified lithium iron phosphate dedicated PVDF): High peel strength and regular molecular weight distribution, exclusively for large-capacity energy storage lithium iron phosphate cell production lines of the client, with performance benchmarked against Arkema V900, enabling electrode sheets to resist calendering without powder shedding.
Lantian copolymer LD-36: A high-purity integrated copolymer grade under central state-owned enterprises with metal ion content far below industry limits and optimal impurity control, exclusively for small-batch mass production lines of the client’s high-end customized vehicle medium-nickel ternary cells, resolving high-temperature swelling risks of high-standard vehicle cells and filling gaps in the client’s high-end segmented material supply.
1. Coordinate sample production of three grades in batches: HiSiaddi coordinated priority scheduling from two manufacturers, produced COA quality inspections uniformly in accordance with Korean client testing standards, entrusted SGS to issue third-party physical, chemical and electrochemical test reports for the same batch, and sent three samples simultaneously to Korean laboratories for full-item verification including immersion, cycle aging and slurry preparation.
2. Comprehensive cost optimization: Compared with original imported procurement prices, the comprehensive procurement cost of three domestic grades dropped by 28.7%. HiSiaddi signed quarterly price protection agreements with two manufacturers to avoid raw material price hikes during peak seasons.
3. One-stop compliance document packaging: Issue bilingual Chinese-Korean MSDS, material traceability documents and factory quality inspection data in accordance with South Korea KC and REACH regulations, adopt unified vacuum moisture-proof aluminum foil packaging and ship via constant-temperature containerized ocean freight.
1. All sample verifications passed, and initial 2.2-ton order successfully signed and implemented: Full-process bench-scale testing of three PVDF samples at the Korean factory confirmed compliance. The universal FL2052 perfectly adapted to dual-system slurry preparation without slurry gelation or coating pinholes; the lithium iron phosphate FL2032 grade maintained 91.2% peel strength retention after 1,000 cell cycles; the vehicle-dedicated Sinochem Lantian LD-36 grade showed no swelling after 45℃ high-temperature cycling. All three products passed the client’s full-item incoming audit, and the client officially issued the initial 2.2-ton trial procurement order, which completed production and delivery on schedule. After customs clearance and warehouse entry in South Korea, full-line mass production was launched, maintaining cell yield at 98.3%, consistent with production standards of original imported raw materials.
2. Signing of long-term annual 35-ton procurement framework: After successful small-batch trial implementation, Korea ESS Power officially signed an annual framework procurement agreement with HiSiaddi, stipulating stable supply of a total of 35 tons divided into 8 batches annually. FL2052 served as the main mass production material accounting for 62% of annual procurement volume, with supplementary orders for the remaining two grades arranged on demand.
3. Client supply chain expansion referrals: Relying on this professional neutral brand selection service, the client included HiSiaddi as its designated Chinese PVDF procurement service provider, and referred two additional leading South Korean energy storage cell enterprises to HiSiaddi for domestic PVDF brand selection and procurement leveraging its South Korean energy storage industry resources, continuously expanding the mid-to-high-end lithium raw material market in South Korea.
All three implemented products of this project are mid-to-high-end lithium battery binder PVDF for dual vehicle and energy storage scenarios, with technical indicators benchmarked against international top brands Solvay and Arkema, differentiated from low-grade general PVDF products for anti-corrosion, pipe and coating applications. Breaking the industry drawback of exclusive one-sided promotion by domestic manufacturers, HiSiaddi, as a neutral third-party foreign trade service provider, objectively horizontally analyzed advantages and disadvantages of five domestic leading brands, and accurately screened two brands with three matching models based on the client’s actual production working conditions. It resolved overseas mid-to-high-end clients’ information asymmetry pain points through professional brand selection services, serving as a typical implementation case of refined fluorochemical foreign trade achieving differentiated services through professional selection, distinct from low-end spot goods resale trade.
