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.
The comprehensive properties of PP are better than that of PE. PP products are light in weight, good in toughness and good in chemical resistance. Disadvantages of PP: low dimensional accuracy, insufficient rigidity, poor weather resistance, easy to produce "copper damage", it has the phenomenon of t shrinkage, easy aging, brittle, easy deformation after demoulding. In daily life, the commonly used fresh-kee box is made of PP material. In order to prevent photoaging, it is necessary to add UV absorber into PP, which can transform the UV absorption of 290 ~ 400nm into non destructive long wavelength light. For the PP plastic products buried in the soil or used indoors in the dark, only the main and auxiliary antioxidants can be added, and the ultraviolet absorber is not needed. The shrinkage and crystallinity of PP are lower than that of PE. PP has a certain permeability to oxygen, carbon dioxide and water vapor. Compared with nylon PA and polyester PET, PP is much worse than nylon PA and polyester PET, but it is much worse for high barrier plastics such as PVDC and EVOH. But compared with other non plastic materials, its air tightness is quite good. The air tightness can be greatly improved by adding barrier materials or coating barrier plastics on the surface. PP is a non-polar polymer with good properties
The tensile strength and rigidity of PP are good, but the impact strength is poor, especially at low temperature. In addition, if there is orientation or stress in the molding process, the impact strength will be significantly reduced. Although the impact strength is poor, its mechanical properties can compete with high cost engineering plastics in many fields after filling or strengthening. The surface hardness of PP is lower than that of PE. When the crystallinity is high, the hardness also increases, but it is still lower than PVC, PS, ABS and so on. Among the five general plastics, PP has the best heat resistance. PP plastic products can work at 100 ℃ for a long time. Without external force, PP products will not deform when heated to 150 ℃
PP的综合性能优于PE料。PP产品质轻、韧性好、耐化学性好。PP的缺点:尺寸精度低、刚性不足、耐候性差、易产生“铜害”,它具有后收缩现象,脱模后,易老化、变脆、易变形。日常生活中,常用的保鲜盒就是由PP材料制成。为防止光老化需要在PP中加入紫外线吸收剂,它可将波290~400nm的紫外线吸收激化转化为没有破坏性的较长波长的光线。对于埋在土壤中或在室内避光使用的PP 塑料制品仅加入主辅抗氧剂即可,无须加入紫外线吸收剂。PP的收缩率和结晶度比PE低。PP对氧气、和水蒸汽都有一定的透过性,比起尼龙PA和聚酯PET都有明显差距,对于高阻隔性塑料,如PVDC、EVOH等就差得更多了。但与其它非塑料材料相比其气密性还是相当好的。通过添加阻隔性材料或在表面涂敷阻隔性塑料,可以提高其气密性。PP属于非极性聚合物,具有良好的电绝缘性,且PP吸水性极低,电绝缘性不会受到湿度的影响。PP的介电常数、介质损耗因数都很小,不受频率及温度的影响。PP的介电强度很高,且随温度上升而。这些都是在湿、热环境下对电气绝缘材料有利的。另一方面PP的表面电阻很高,在一些场合使用必须行抗静电处理
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,冲击强度也会显著降低。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。
