均聚物聚丙烯原料TD20 TD40冰箱抽屉颗粒

聚丙烯等级可用

目前有三种类型的聚丙烯可用。每一种都适合特定的规格和成本（尽管经常有一些重叠）

均聚物-一种可用于各种不同应用的通用级

嵌段共聚物——含有5-15%的乙烯，在-20℃以下的温度下，抗冲击性大大提高。通过添加冲击改性剂（传统上是在共混过程中添加弹性体），可以进一步增强其韧性

无规共聚物-包含沿着聚丙烯长链分子随机排列的共单体单元（不同于离散嵌段）。选择通常含有1-7%乙烯的此类聚合物，其中熔点较低、更灵活和透明度增强是有利的

根据应用和选择的加工方法，可提供不同的PP等级

PP Grades Available

Three types of polypropylene are currently available. Each suits particular specifications and costing (although there is often some overlap).

Homopolymers- A General Purpose Grade that can be used in a variety of different applications.

Block copolymers- incorporating 5-15% ethylene, have much improved impact resistance extending to temperatures below -20oC. Their toughness can be further enhanced by the addition of impact modifiers, traditionally elastomers in a blending process.

Random copolymers- incorporate co-monomer units arranged randomly (as distinct from discrete blocks) along the polypropylene long chain molecule. Such polymers typically containing 1-7% ethylene are selected where a lower melting point, more flexibility and enhanced clarity are advantageous.

Different PP grades are available dependent on the application and chosen processing method.
