- Stepped Rigidity & Strength Enhancement: Material stiffness, hardness, and flexural capability increase noticeably with higher mineral content (10%–50%)
- Superior Dimensional Stability: Substantially reduces injection molding shrinkage and internal stress, effectively preventing warpage and sink marks in thick-walled or large-surface parts
- Enhanced Heat Resistance: Elevates Heat Deflection Temperature (HDT), suitable for long-term elevated temperature or load environments
- High-Density Vibration Damping: The 50% high-fill grade exhibits high-density characteristics, offering exceptional vibration damping and supreme flatness
- Favorable Processability & Cost-Efficiency: Balances injection flowability with cost efficiency—a modified solution combining structural strength and appearance
- Customizable Colors: Professional color-matching specialists available to discuss and customize any color requirement
This series features composite polypropylene modified with 10% to 50% fine minerals (Mineral Filled, such as talc/calcium carbonate; PP-MF Series). The addition of fine minerals markedly boosts stiffness, hardness, and thermal performance while significantly reducing molding shrinkage, attaining high dimensional accuracy and warping prevention.
We provide complete filling ratios of 10%, 20%, 25%, 30%, and 50%:
10% ~ 25%: Balances stiffness and impact toughness with good injection flowability; ideal for appliance housings, auto interior trim, furniture fittings, and everyday items.
30% ~ 50%: Offers ultra-high rigidity, high heat resistance, and exceptionally low shrinkage; ideal for auto engine compartment surrounding parts, HVAC blower housings, appliance bases, speaker enclosures, and heavy-duty industrial crates.
