This client is an enterprise specializing in modified PP plastics for automotive applications, including bumpers, dashboards, and door panels. With growing demands for lightweighting and safety, traditional fillers such as calcium carbonate were causing reduced toughness, low-temperature brittleness, and rising customer complaints. A high-performance alternative was urgently required.
- Insufficient toughness: Conventional fillers lowered impact resistance in cold environments, compromising safety of critical auto parts.
- Low processing efficiency: Poor filler dispersion led to weak flowability in injection molding, with a pass rate of only 85%.
- High cost pressure: Heavy use of plasticizers to offset performance gaps drove up production costs.
We provided 1250-mesh modified talc powder with tailored technical support:
- High-purity selection: SiO₂ ≥60% to prevent impurities from accelerating plastic aging.
- Surface modification: Composite coating improved dispersion, eliminated agglomeration, and enhanced compatibility with the PP matrix, boosting mechanical strength.
- Low oil absorption design (≤30 g/100 g): Reduced plasticizer usage by 15%, directly cutting formulation costs.
- Performance upgrade: Impact strength of PP materials improved by 25% at -30 °C, passing low-temperature testing.
- Production efficiency: Injection molding flowability improved, raising pass rate from 85% to 98% and saving over RMB 2 million annually in scrap costs.
- Market success: Customer complaint rate dropped 90%, orders grew 30% year-on-year, and the company secured entry into the supply chain of leading new-energy vehicle brands.
“Traditional fillers had long limited the competitiveness of our products. After switching to JINGHUA’s talc powder, we not only solved the issue of low-temperature brittleness but also reduced overall costs. We have now upgraded our entire PP product line with this solution.”
