聚碳酸酯PC价格

比重：1.18-1.20 g/cm3

成型收缩率：0.5-0.8%

成型温度：230-320°C

干燥条件：110-120°C持续8小时

<。无色透明，着色好。良好的电气绝缘性、耐腐蚀性和耐磨性，但自润滑性较差，有应力开裂倾向，高温易水解，与其他树脂混溶

适用于制造仪器小型零件、绝缘透明零件和耐冲击零件

可成形性。非晶态材料，热稳定性好，成型温度范围宽，流动性差。吸湿性小，但对水敏感，必须干燥

成型收缩率小，容易发生熔融开裂和应力集中，因此成型条件应严格控制，塑料件必须进行退火处理

2。熔融温度高，粘度高，塑料件200克以上，适宜使用加热型延伸喷嘴

3。冷却速度快。模具浇注系统应厚而短，冷料井应设置，浇口应大，模具应加热

4材料温度过低会导致材料不足，塑料零件无光泽，材料温度过高容易溢出边缘，塑料零件起泡。当模具温度较低时，收缩率和伸长率具有较高的冲击强度，而圆顶、压缩和拉伸强度较低。当模具温度超过120度时，塑料零件冷却缓慢，容易变形并粘在模具上

Product Details

Polycarbonate PC Price

Specific gravity :1.18-1.20 g/cm3

Molding shrinkage rate :0.5-0.8%

Molding temperature: 230-320°C

Drying conditions: 110-120°C for 8 hours

Material properties: high impact strength, good dimensional stability. Colorless and transparent, good coloring. Good electrical insulation, corrosion resistance and wear resistance, but self lubricity

Poor, stress cracking tendency, high temperature easy hydrolysis, miscibility with other resins.

Suitable for making instrument small parts, insulating transparent parts and impact resistant parts.

formability

1. Amorphous material, good thermal stability, wide molding temperature range, poor liquidity. Small moisture absorption, but sensitive to water, must be dried.

Molding shrinkage rate is small, easy to occur melting cracking and stress concentration, so the forming conditions should be strictly controlled, plastic parts must be annealed.

2. High melting temperature, high viscosity, more than 200g plastic parts, appropriate to use heating type of extension nozzle.

3. Fast cooling speed. The mold gating system should be thick and short, and the cold material well should be set, the sprue should be large, and the mold should be heated.

4 material temperature is too low will cause the lack of material, plastic parts without luster, material temperature is too high easy overflow edge, plastic parts bubble. When the mold temperature is low, the shrinkage and elongation have high impact strength, and the dome, compression and tensile strength are low. When mold temperature exceeds 120 degrees, plastic parts cool slowly and are easy to deform and stick to the mold
