Detailed Product Description

Specific gravity: 1.05g/cm3.
Moulding minification: 0.3-0.6%
Moulding temperature: 180--280^oC.
Usage: which is widely used to the end of the window.

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, 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.
