The plastics division of Taihua was originally the second division of chemical industry. In the early stage, it was established to cooperate with the development of upstream and downstream related industries in the sixth light industry plan of Formosa Plastics. At that time, it was responsible for the construction of aromatic hydrocarbon and styrene series plants. Due to the delay in the plant site of the Liuqing project, it was decided that the downstream polystyrene company should build the plant first and introduce its products into the market, so as to facilitate the production of upstream products in the future Pin.
聚丙烯是丙烯加聚反应而成的聚合物,一种有机物。系白色蜡状材料,外观透明而轻。化学式为(C3H6)x,密度为0.89~0.91g/cm3, 易燃,熔点165℃,在155℃左右软化,使用温度范围为-30~140℃ 。在80℃以下能耐酸、碱、盐液及多种的腐蚀,能在高温和氧化作用解

PP力学性能 的拉伸强度和刚性都比较好,但冲击强度较差,特别是低温时耐冲击性差。此外,如果制品成型时存在取向或应力,冲击强度也会**降低。虽然抗冲击强度差,但经过填充或增强等改性后,其机械性能在许多领域可与成本较高的工程塑料相竞争。PP 的表面硬度在五类通用塑料中属低等,仅比PE 好一些。当结晶度较高时,硬度也相应增加一些,但仍不及PVC、PS、ABS 等。热性质在通用塑料中,PP的耐热性是。PP 塑料制品可在100℃下长时间工作,在无外力作用时,PP制品被加热至150℃时也不会变形。

Although PP has higher mechanical strength and modulus than recycled PE, the impact resistance, especially stress cracking resistance, and low temperature performance of recycled PP are poor, like the new PP resin. These properties are determined by the aggregation structure and macromolecular chain structure of PP, so it can be modified by polyethylene. When the blends of recycled PE (LDPE, HDPE) and PP are made, if there are more recycled PP materials, the alloy can be directly prepared. For example, if 10% - 25% HDPE is added into PP, the impact strength of the modified blend is increased by more than 8 times than that of PP at - 20 ℃, and the processing fluidity is increased, so it can be applied to the molding of large containers. In terms of structure, the addition of PE destroys the crystallization of PP, such as the fragmentation of macrospherulites, and also reduces the crystallinity of PP; if EPDM is added into the system, the crystallization of PP is also reduced. About 5% can improve the compatibility of PP and PE, and the impact strength can also be improved by adding a small amount of EPR rubber.

PP化学改性:通过共聚改性、交联改性、接枝改性、添加成核剂等使PP(聚丙烯)高分子组分与大分子结构或晶体构型发生改变而提高其机械性能、耐热性、耐老化性等性能,提升其综合性能、扩大其应用领域
