电动门开关用阻燃聚丙烯颗粒

聚丙烯成型特性

1、结晶、吸湿性小、易发生熔体破裂、长期接触热金属易于区分

2，活性好，但缩短范围和缩短值大，容易出现缩孔、凹痕、变形

3、冷却速度快，浇注系统和冷却系统应缓慢冷却，并注意控制成型温度，材料温度低温高压易取向，模具温度低于50度，塑件不光滑，易发生熔合不良，流痕，90度以上易发生翘曲变形

4，塑料壁厚应均匀，防止缺胶、尖角，以防止应力聚集

Fire retardant PP Pellets for electric gate switch

PP molding characteristics

1, crystalline, small moisture absorption, easy to occur melt break, long-term and hot metal touch easy to differentiate.

2, good activity, but shorten the range and shorten the value of large, prone to shrink holes, dents, deformation.

3, fast cooling speed, pouring system and cooling system should be slow cooling, and pay attention to control molding temperature, material temperature low temperature and high pressure easy orientation, mold temperature is less than 50 degrees, plastic parts are not smooth, easy to occur bad fusion, flow marks, more than 90 degrees prone to warping deformation.

4, plastic wall thickness should be uniform, to prevent lack of glue, sharp angle, in order to prevent stress will collect.

is one of the professional fire retardant pp pellets for electric gate switch manufacturers, you can order high quality fire retardant pp pellets for electric gate switch at good price from our factory.
