Detailed Product Description

Product name: PP extrusion, plastic fitting

Specific gravity: 0.90.91g/cm3.
Moulding minification: 1.0-2.5%.                                                                          
Moulding temperature: 160--220^oC.                                                                          

Features:                                        

1. Crystalline materials, hygroscopicity small, vulnerable to financial rupture, long-term contact with the thermal decomposition of metal.
2. Good liquidity, But contraction scope and value of contraction, prone to shrinkage. Dent, deformation.                                                                                     
3. cooling speed, Gating system and the cooling system should slow cooling, and attention to the molding temperature control. Liu Wen significantly lower directional orientation. Low-temperature high-pressure particularly obvious, Mold temperature below 50 ° C, plastics not smooth and easy to produce fusion bad, traces, 90 prone to warpage
4. Plastic uniform wall thickness to avoid shortage of plastic, pointed to avoid stress concentration.
