End Buyer: Elaplast GmbH, Germany A mid-to-high-end German terminal manufacturer, not a trading intermediary. Located in Bavaria, Germany, Elaplast GmbH has 32 years of R&D and manufacturing experience in premium food sealing gaskets, medical silicone composite auxiliary materials, and low-temperature eco-friendly PVC films. Its products supply major European dairy and medical device manufacturers, complying with EU 10/2011, FDA 21CFR, and full REACH registration requirements, with an annual stable DBS procurement volume of 95 tons. The client previously sourced refined European imported DBS. Amid European domestic raw material price hikes and extended lead times to 90 days, the client launched a localized Chinese DBS selection project aiming to lock one fixed long-term supplier. The client independently contacted five leading domestic DBS manufacturers: Zhejiang Huangma, Shandong Yuanli, Jiangsu Hualun, Arkema Keda, and Shandong Langhui for inquiries and sample submission, encountering a widespread industry pain point: each manufacturer’s sales team only promotes its own product advantages, avoids objective elaboration of peer strengths, and refuses horizontal parameter benchmarking without defaming competitors.
1. Huangma only promotes its food-grade DBS, highlighting FDA certification advantages while omitting Yuanli’s integrated raw material supply and low-temperature stability strengths.
2. Yuanli emphasizes its full sebacic acid industrial chain self-sufficiency and cost advantages without explaining Hualun’s PVC formulation compatibility and compound stability characteristics.
3. Hualun focuses on integrated auxiliary agent supply while avoiding introducing Keda’s bio-based raw material and low-precipitation advantages.
4. Keda markets imported-process castor-oil bio-based DBS without disclosing Langhui’s large-scale mass production and batch stability strengths.
5. Langhui highlights large production capacity and controllable delivery cycles without elaborating rectification details of other premium brands. The client received five sets of samples and product brochures but lacked horizontal comparison criteria to distinguish industrial-grade, food-grade, and refined pharmaceutical-grade DBS. Laboratory testing revealed low-temperature precipitation and high-temperature odor in partial samples, halting brand selection for half a month. The client entrusted HiSiaddi with neutral third-party brand evaluation and grade screening, with core mandatory indicators: ester content ≥99.6%, color ≤10 APHA, acid value ≤0.03 mgKOH/g, low migration, suitable for dual food & medical scenarios.
Drawing on its plasticizer technical database, HiSiaddi compiled a horizontal comparison table covering mainstream grades, process routes, compliance certifications, applicable scenarios, and inherent drawbacks of the five brands, analyzing each brand for the German client:
Main Grades: RM-F Food-Grade DBS, RM-M Refined Pharmaceutical-Grade DBS Strengths: Early domestic completion of FDA and EU 10/2011 compliance filings with mature rectification processes and strict control over small-molecule impurities; measured low migration rates in food packaging applications. Weaknesses: High minimum order quantity for refined pharmaceutical grades, obvious price surcharges for bulk orders, inferior low-temperature cold resistance versus bio-based route products.
Main Grades: YL-U Premium Industrial DBS, YL-M High-Purity Refined DBS Strengths: Self-owned sebacic acid production line with full industrial chain integration; no externally sourced miscellaneous raw materials, stable batch color difference, controllable mass-production costs, and consistent bulk delivery cycles. Weaknesses: General premium grades feature limited refining depth with high thermal weight loss; only high-purity grades meet medical standards.
Main Grades: HL-STD General DBS, HL-PVC Special Modified DBS Strengths: Specialized in PVC auxiliary agent matching; DBS exhibits excellent compatibility with calcium-zinc stabilizer systems, resisting blooming during pipe extrusion when compounded with epoxy auxiliary agents. Weaknesses: No bio-based grades; delayed updates to high-end food-grade compliance documentation.
Main Grades: Oleris-B Bio-Based DBS, Oleris-M Pharmaceutical-Grade DBS Strengths: French production processes with castor-oil bio-based sebacic acid synthesis, industry-leading low-temperature toughness, ultra-low heavy metal impurities, performance benchmarking original European raw materials. Weaknesses: Highest product pricing across all brands, high surcharges for small-batch samples, limited domestic warehousing points.
Main Grades: LH-G General-Grade, LH-H High-Purity Refined DBS Strengths: Comprehensive East China warehousing for fast spot turnover, outstanding cost performance for super-large orders, uniform batch consistency via continuous large-scale production lines. Weaknesses: Limited production capacity for high-end pharmaceutical grades with priority allocation to domestic key clients, extended export scheduling cycles.
The client operates two production lines covering food sealing (prioritizing compliance and low migration) and medical auxiliary materials (prioritizing low-temperature performance and low impurities). HiSiaddi eliminated Hualun and Langhui due to insufficient overall matching, finalizing two mid-to-high-end brands (Zhejiang Huangma & Shandong Yuanli) with three applicable grades for segmented procurement:
1. RM-F Food-Specific DBS: Dedicated to food rubber sealing gasket production with full FDA & EU compliance documentation to eliminate raw material migration risks; fixed annual procurement of 60 tons.
2. RM-M Refined Pharmaceutical DBS: Small-batch on-demand procurement for high-end medical composite film R&D and small-lot mass production, 3–5 tons monthly.
1. YL-M High-Purity Refined DBS: Replaces partial imported materials for general low-temperature resistant medical PVC films, leveraging full industrial chain cost advantages for bulk stock; annual procurement of 35 tons. Selection Logic:
2. Eliminate Keda: Optimal bio-based product performance but procurement costs exceed the client’s budget by 28%, failing project pricing limits.
3. Eliminate Hualun & Langhui: Hualun lacks in-depth medical compliance certifications; Langhui faces tight high-end grade production capacity and unstable delivery cycles, unsuitable for long-term framework cooperation.
4. Huangma delivers comprehensive food compliance while Yuanli provides bulk cost advantages and stable batch consistency; dual-brand matching fully covers the client’s two production line requirements.
1. Sample Phase: HiSiaddi coordinated unified sample delivery from both manufacturers. Full physical & chemical, migration, and low-temperature testing were conducted at the client’s German laboratory; all three grades passed inspection with performance deviation <1.5% versus original European imported materials.
2. Trial Order Phase: Initial trial order: 12 tons from Huangma (8 tons RM-F + 4 tons RM-M) and 8 tons YL-M from Yuanli, shipped from Shanghai Port to Hamburg. Full-line continuous production ran for 15 days post delivery, yielding precipitation-free gaskets and crack-resistant low-temperature films with finished product yield equivalent to imported raw materials.
3. Annual Contract Sign-off: Finalize a 95-ton annual framework contract with 60 tons/year from Huangma and 35 tons/year from Yuanli, shipped in 12 monthly batches. Overall procurement costs dropped by 27.5% versus original European imports, with delivery lead time compressed to 30–35 days.
1. The client launched a new low-temperature biodegradable film project the following year, sourcing small volumes of Keda bio-based DBS for high-end new product R&D via HiSiaddi’s brand database.
2. Elaplast entrusted HiSiaddi with permanent trusteeship for brand selection and sample coordination of all low-temperature plasticizers including DBS, ATBC, and epoxidized soybean oil.
3. Huangma and Yuanli optimized exclusive export grades based on test data from the German client, enabling HiSiaddi to develop equivalent high-end plastic manufacturers in Austria and the Netherlands.
1. Industry Pain Points: Domestic DBS manufacturers prioritize sales of their own products without willingness to conduct horizontal peer benchmarking, only highlighting internal product strengths. Overseas mid-to-high-end clients lack familiarity with China’s three-tier DBS grading system (industrial / food / refined pharmaceutical) and risk selecting inappropriate grades and triggering mass production defects if relying solely on unilateral manufacturer introductions.
2. Core Value of HiSiaddi: Conduct neutral third-party horizontal analysis of multi-brand advantages and disadvantages, break free from single-manufacturer sales bias, and accurately match grades aligned with client end-formulation and regulatory requirements to avoid selection risks.
3. Procurement Logic of High-end Clients: European and American mid-to-high-end clients evaluate more than unit price; they value transparent brand grading, precise grade matching, complete compliance documentation, and flexible multi-brand allocation. Neutral brand selection services are the key to securing long-term bulk annual orders. Contact HiSiaddi customer service for more cross-brand model comparison analysis.
