产品详细信息

透明聚丙烯FI15-25 PP颗粒

线性碳氢化合物聚合物，很少或没有不饱和度。在许多性质上类似于聚乙烯，尤其是溶液和电气性质。然而，连接到每个交替主链碳原子的甲基的存在可以以多种方式改变性质：

（i）它可以导致链的轻微硬化，增加结晶熔点（Tm）

（ii）它会干扰分子对称性——降低结晶度，从而降低Tm

Product Details

Transparent PolypropyleneMFI15-25 PP Granules

Linear hydrocarbon polymer, little or no unsaturation. Similar to polyethylene in many properties, especially solution and electrical. However, the presence of the methyl group attached to every alternate backbone chain carbon atom can alter the properties in a number of ways:

(i) it can cause a slight stiffening of the chain – increasing the crystalline melting point (Tm);

(ii) it can interfere with the molecular symmetry – depressing crystallinity and hence Tm.
