PP Calcium Carbonate Filled Resin Pellets - Cost-Effective·High Rigidity·Dimensional Stability Solution
I. Core Selling Points
✅ Cost Optimization: 30-60% CaCO₃ filling, reduces raw material cost by 15-30% vs. pure PP, no compromise on key performance
✅ Enhanced Rigidity: Flexural modulus ≥2500MPa (30% filling), 50% higher than pure PP, excellent load-bearing for structural parts
✅ Dimensional Stability: Shrinkage rate 0.8-1.2%, low warpage (tolerance ±0.03mm), adapts to large-size injection molding
✅ Processing Friendly: Compatible with existing PP production lines, melt flow rate 8-25g/10min, short molding cycle
✅ Eco & Compliance: Food-contact safe (FDA 21 CFR §177.1520), RoHS/REACH compliant, 100% recyclable, low VOC
✅ Customizable Filling: 20-60% CaCO₃ filling ratio, optional modification (toughness/UV resistance/flame retardancy)
