高刚性聚丙烯塑料材料

聚丙烯塑料原材料简介：

聚丙烯塑料原材料，化学名称：聚丙烯，特点：低密度、强度、刚度、，硬度和耐热性均优于低压聚乙烯，可在100度左右使用。它具有良好的电气性能和高频绝缘性，不受湿度影响，但在低温下会变脆，不耐磨，并且容易老化。适用于制造一般机械零件、耐腐蚀零件和绝缘零件。

成型特点：

1。结晶材料，吸湿性低，易熔化和破裂，长期接触铁水后易分解

2。流动性好，但收缩范围和收缩值大，容易出现缩孔、凹痕和变形

3。冷却速度快，浇注系统和冷却系统应缓慢散热，并注意控制成型温度。材料温度在低温高压下易于定向。当模具温度低于50度时，塑料零件不光滑，容易产生不良的焊接和流痕。90度以上容易发生翘曲变形

4。塑料墙的厚度必须均匀，以避免缺少胶水和尖角，防止应力集中

Product Details

High rigidity PP Plastic Material

Introduction of PP plastic raw materials:

PP plastic raw material, chemical name: polypropylene, features: low density, strength, stiffness, hardness and heat resistance are better than low pressure polyethylene, can be used at about 100 degrees. It has good electrical properties and high-frequency insulation and is not affected by humidity, but becomes brittle at low temperature, not wear-resistant, and easy to age. Suitable for making general mechanical parts, corrosion-resistant parts and insulating parts

Molding characteristics:

1. Crystalline material, with low hygroscopicity, easy to melt and rupture, and easy to decompose after long-term contact with hot metal.

2. The fluidity is good, but the shrinkage range and shrinkage value are large, and shrinkage holes, dents and deformations are prone to occur.

3. The cooling speed is fast, the pouring system and cooling system should slowly dissipate heat, and pay attention to controlling the molding temperature. The material temperature is easy to orient at low temperature and high pressure. When the mold temperature is lower than 50 degrees, the plastic parts are not smooth, and it is easy to produce poor welding and flow marks. Warp deformation is easy to occur above 90 degrees.

4. The thickness of the plastic wall must be uniform to avoid lack of glue and sharp corners to prevent stress concentration.
