PP为结晶型高聚物，常用的塑料中PP最轻，密度仅为0.91g/cm3（比水小）。通用塑料中，PP的耐热性比较好，其热变形温度为80-100℃，能在沸水中煮。PP有良好的耐应力开裂性，有很高的弯曲疲劳寿命，俗称“百折胶”。PP的综合性能优于PE料。PP产品质轻、韧性好、耐化学性好。

密度小，易焊接和加工，具有优越的耐化性，耐热性及耐冲击性、无毒、无味是目前较符合环保要求之工程塑料之一。

  1.结晶料,吸湿性小,易发生融体破裂,长期与热金属接触易分解.

  2.流动性好,但收缩范围及收缩值大,易发生缩孔.凹痕,变形.

  3.冷却速度快,浇注系统及冷却系统应缓慢散热,并注意控制成型温度.料温低温高压时容易取向,模具温度低于50度时,塑件不光滑,易产生熔接不良,流痕,90度以上易发生翘曲变形

  4.塑料壁厚须均匀,避免缺胶,尖角,以防应力集中.

Wasn't it odd that she didn't know who she was? And wasn't it unreasonable that she hadn't been allowed to have any say in what she would look like? Her looks had just been dumped on her. She could choose her own friends, but she certainly hadn't chosen herself. She had not even chosen to be a human being. My raft was now strong enough to bear any reasonable weight. My next care was what to load it with, and how to preserve what I laid upon it from the surf of the sea; but I was not long considering this. I first laid all the planks or boards upon it that I could get, and having considered well what I
