Headquartered in Seoul, Hanhua total petrochemical complex, which is comed of 13 independent factories, is located in Dashan, Nandao Province, Zhongqing. The company has 1100 employees, and its president and CEO is son seog won.
在共混改性中必须注意不同聚合物之间的相容性，在相容性较差的两种聚合物共混时，往往需要加入分别和两种聚合物相容性都好的*三组分，称之为相容剂。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先进行抗静电处理。PP在工业领域和生活消费领域的应用必将得到更为迅猛的发展.PP在我国的销量已一个月大约70万吨左右，目前中国是世界上用量的消费国，随着生活的多姿多彩PP产品越来越多，让消费者感受到科学的优越性。

Calcined kaolin is added to improve the electrical insulation of PP, Adding wollastonite needle shape can enhance the surface hardness of PP, increase the surface gloss and material density of PP products by adding precipitated barium sulfate barite powder. Aluminum hydroxide and magnesium hydroxide brucite powder are used as flame retardants to achieve the triple effects of filling, flame retardancy and smoke elimination. Conductive plastics are made by adding carbon black. PP achieves permanent antistatic effect and improves light aging resistance Metal powder is used to make conductive plastics to achieve permanent antistatic effect. Wood powder is added to reduce cost and facilitate resource recycling. Graphite, molybdenum disulfide and polytetrafluoroethylene are added to improve lubricity and reduce friction. For PE, PP and PVC ternary blends, in addition to compatibilizers CPE and EPR, alloy can also be prepared by reactive extrusion technology.

PP products are light in weight, good in toughness and good in chemical resistance. Disadvantages of PP: low dimensional accuracy, lack of rigidity, poor weather resistance, easy to produce copper damage, it has t shrinkage phenomenon, easy to aging, brittle, easy to 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先进行抗静电处理。PP是高结晶塑料，它在熔点的附近时，它的液态和固态的体积相差很大，加上它收缩时的各向异性，因此易引起不均衡收缩即缩水；因此，设计制品时，尽量避免壁厚不均匀；聚丙烯的熔体粘度小，流动性好，流长比流动长度与厚度的比值大，薄壁制品可能也能注满；但同时，它的模具制作时，精度要高，否则会批峰；因它的各向异性，制品经常是变形。收缩率为18‰；溢边值为0.03mm。聚丙烯不吸水，一般不需烘干，有时为了产品质量，也可以用60℃的温度，烘干30分钟至1个小时，以排出原料中的浮水。
