Product Specification: Modified Polypropylene CP-212 (Beige)
1. Product Positioning
CP-212 is a high-performance Modified Copolymer Polypropylene specifically engineered for home appliances, electronics, and industrial structural components. Featuring a classic Beige (Off-white) finish, this grade is formulated to provide an optimal balance of mechanical strength, heat resistance, and aesthetic consistency. It is an ideal choice for manufacturers seeking a durable, cost-effective material with high surface quality.
2. Key Features and Benefits
Excellent Impact-Stiffness Balance: The copolymer-based matrix ensures high impact resistance—even at lower temperatures—while maintaining the necessary rigidity for structural integrity.
Thermal Stability: CP-212 offers an elevated Heat Deflection Temperature (HDT), allowing it to withstand the operational heat generated by internal electronic components without deforming.
Long-term Color Stability: Enhanced with specialized anti-yellowing agents and UV stabilizers, the "Beige" hue remains consistent over time, resisting discoloration caused by indoor lighting or thermal aging.
Superior Processability: Optimized Melt Flow Rate (MFR) allows for easy injection molding of complex shapes and large parts, resulting in shorter cycle times and lower production costs.
Dimensional Precision: Low mold shrinkage ensures that molded parts remain true to their design, facilitating seamless assembly and tight tolerances.

5. Processing Guidelines
Drying: Although PP has low moisture absorption, pre-drying at 80°C for 1–2 hours is recommended to ensure a high-gloss, defect-free surface.
Melt Temperature: Recommended range is 200°C - 230°C. Avoid overheating to prevent oxidative shifts in the beige pigment.
Mold Temperature: 40°C - 60°C. Higher mold temperatures can improve surface finish and reduce weld lines.
Injection Pressure: Use moderate pressure with adequate holding time to prevent sink marks on thicker sections.
