Please contact HiSiaddi customer service for additional cross-brand and cross-model comparative analysis.

I. Client Profile (Typical Mid-to-High-End Client)

Client: Germany K-tech Modified Plastics Co., Ltd. (referred to as Company K) Industry Position: A mid-to-high-end European modified plastics manufacturer specializing in modified PP/PE materials for automotive interiors, premium home appliance housings and outdoor photovoltaic frames. Its products supply tier-one brands including Volkswagen and Bosch, requiring stringent standards for additive stability, batch consistency and compliance, rejecting low-end generic manufacturers.

Procurement Demand: Bulk purchase of LS-944 light stabilizer for anti-aging treatment of high-end modified plastics, requiring low volatility, migration resistance, superior thermal stability, REACH/RoHS compliance and minimal batch variation. The client previously sourced imported BASF LS-944 but planned to shift to mid-to-high-end Chinese brands due to high costs and long lead times (8–10 weeks). However, limited understanding of China’s LS-944 brand landscape, product disparities and application scenarios stalled its supplier selection process.

Core Pain Points: Four contacted Chinese manufacturers only promoted their own brands, emphasizing strengths while avoiding weaknesses without objective cross-brand comparisons. The client could not horizontally evaluate technical parameters, quality stability and application scenarios, fearing incorrect brand selection would trigger product quality fluctuations and delay deliveries to core end clients, leaving supplier selection deadlocked.

II. Core Client Dilemma: Information Asymmetry & Biased Manufacturer Self-Promotion Impair Decision-Making

1. Blank brand awareness: Company K’s technical team had long collaborated with European and American suppliers, lacking familiarity with mainstream Chinese LS-944 brands (Tiangang, Liansheng, Lianlong, Jadewin, etc.) regarding technical strength, market positioning and product portfolios, unable to distinguish mid-to-high-end brands from low-end generic alternatives.

2. One-sided manufacturer promotion lacking objective cross-brand benchmarks:

· Beijing Tiangang: Prioritized LS-944, highlighting "national high-tech enterprise, 10,000-ton annual capacity, exports to 50 countries" without acknowledging its premium pricing and slow small-batch lead times;

· Suqian Liansheng: Promoted UNITECHEM LS-944, emphasizing "low volatility & high purity" while omitting limited experience supporting high-end modified materials;

· Qingdao Jadewin: Marketed JADEWIN LS-944, highlighting "cost-effectiveness & fast lead times" without disclosing slightly inferior thermal stability;

· Other manufacturers only showcased their own advantages, failing to objectively outline technical highlights and applicable scenarios of competing brands, preventing the client from conducting horizontal comparisons.

1. High selection risk: As a mid-to-high-end client, Company K could not afford losses from additive misselection triggering product yellowing, precipitation or mechanical performance degradation, which would risk losing core clients Volkswagen and Bosch. It urgently required neutral third-party professional analysis and recommendations.

III. HiSiaddi Intervention: Neutral Evaluation & Horizontal Comparison for Targeted Matching Recommendations

Core Advantages: 10 years of deep industry experience, neutral third-party perspective, in-house testing laboratory and technical alignment with 5 leading manufacturers. Unbound to a single brand, we focus on delivering solutions balancing technical compatibility, stable quality and optimal cost.

Step 1: Screen 3–5 mid-to-high-end brands to define evaluation scope Based on market reputation, technical strength, export qualifications and mid-to-high-end client cooperation track records, we shortlisted 5 mainstream mid-to-high-end brands:

1. Beijing Tiangang: Domestic light stabilizer leader, national high-tech enterprise with 10,000-ton Asian production capacity, mid-to-high-end positioning, exporting to 50 European and American countries;

2. Suqian Liansheng: Listed enterprise and core manufacturer of polymeric HALS, mid-to-high-end positioning with standout low volatility and high purity performance;

3. Lianlong: Globally renowned additive manufacturer and domestic leader, mid-to-high-end positioning with rich experience supporting automotive/home appliance modified materials;

4. Qingdao Jadewin: Joint venture with South Korea Songwon, mid-to-high-end cost-effective positioning with fast lead times and flexible small-batch support;

5. Guangzhou L&B: Specialized in high-end additives, mid-to-high-end positioning with excellent migration resistance and low precipitation performance.

Recommended Brand 1: Beijing Tiangang (Top Mid-to-High-End Choice, Most Stable Quality)

· Model HiSiaddi-944LD (Pellet Grade): Purity 99.8%, volatile matter 0.25%, thermal stability 210℃, suitable for automotive interiors and premium home appliances, performance benchmarked against BASF 944 with robust batch consistency, compliant with Volkswagen certification standards;

· Model HiSiaddi-944FD (Powder Grade): Uniform particle size and superior dispersibility, compatible with high-speed extrusion processes to resolve uneven dispersion issues on the client’s high-speed production lines.

Recommended Brand 2: Suqian Liansheng (Mid-to-High Cost-Performance, Outdoor Application Focus)

· UNITECHEM LS-944 Pellets: Volatile matter 0.28%, migration-resistant, transmittance 95%, suitable for photovoltaic frames and outdoor modified PP. Priced 12% lower than Tiangang with 3-week lead times, balancing quality and cost.

Step 4: Full-Link Verification & Technical Endorsement to Eliminate Client Concerns

· Sample testing: Complimentary 5kg samples of 3 models provided, with full-item testing (purity, volatile matter, thermal stability, migration resistance) conducted by SGS per client standards, alongside REACH/RoHS compliance reports;

· Factory site visits: Arranged for Company K’s Technical Director to tour Tiangang and Liansheng manufacturing facilities, inspecting DCS automated production lines, quality control laboratories and batch sample retention records to verify production capacity and quality control protocols;

· Technical benchmark report: Issued a performance comparison report benchmarking the 3 models against BASF 944, clarifying key parameter disparities and applicable scenarios to prove domestic mid-to-high-end grades capable of import substitution.

IV. Cooperation Outcome: Targeted Supplier Selection & Successful Mass Procurement, Establishing Long-Term Stable Partnership

Supplier selection finalized: After reviewing test reports, factory site visits and benchmark data, Company K confirmed Tiangang HiSiaddi-944LD (primary use), HiSiaddi-944FD (backup) and Liansheng LS-944 Pellets (dedicated outdoor line) fully matched its requirements, eliminating all selection concerns.

Mass procurement launched: Trial orders of 500kg per model initiated in Q3 2025. Post successful trial production, stable monthly procurement of 2 tons was secured (1.2 tons Tiangang, 0.8 tons Liansheng), replacing original BASF imports with 25% overall cost reduction and lead times shortened to 3 weeks.

Stable quality post mass production: Finished products passed full testing by Volkswagen and Bosch with no yellowing, precipitation or mechanical performance degradation, delivering superior batch consistency compared to imported grades.

Long-term cooperation deepened: Company K designated HiSiaddi as its exclusive Chinese supplier for LS-944, expanding purchases to light stabilizer 622 and antioxidant 1010, and recommending HiSiaddi to 2 additional German modified plastics peers.

V. Core Value of the Case (Aligned with Mid-to-High-End Client Positioning)

The client is a mid-to-high-end modified plastics enterprise serving automotive and home appliance supply chains, prioritizing quality stability, technical compatibility and compliance rather than low pricing. The core pain point stemmed from information asymmetry regarding Chinese brands and biased manufacturer self-promotion; HiSiaddi broke information barriers via neutral third-party horizontal comparison across 5 major brands, objectively presenting respective strengths and weaknesses. Our recommendation logic prioritized application compatibility over pure low pricing, selecting 2 mid-to-high-end brands and 3 targeted models to match the client’s diverse application scenarios while balancing quality and cost. Our core service strengths include technical empowerment and risk mitigation, eliminating high-end clients’ doubts over domestic product quality through SGS testing, factory site visits and technical benchmarking, ultimately realizing import substitution and long-term cooperative partnerships.
