The PP and PE compound plant of Hanhua Daer Petrochemical Co., Ltd. is located in Dongguan, China; its sales offices are located in Seoul, Busan, Daegu, Guangzhou and Datian; the Asian sales offices are located in Beijing, Shanghai, Shenzhen, Hong Kong, Tokyo and Nagoya.
加煅烧高岭土提高PP电绝缘性,加硅灰石针状有一定增强效果、提高PP表面硬度，加沉淀硫酸钡重晶石粉提高PP制品表面光泽、材料密度，加氢氧化铝、氢氧化镁水镁石粉作为阻燃剂使用，达到填充、阻燃、消烟三重效果，加炭黑制作导电塑料，PP达到*抗静电效果，提高耐光照老化性，加金属粉末制作导电塑料，达到*抗静电效果，加木粉降低成本、有利资源再生利用，加石墨、二硫化钼、聚四氟乙烯提高润滑性、减小摩擦力，对于PE、PP、PVC 三元共混物，除了加人相容剂CPE、EPR 外，还可利用反应挤出技术制备合金。如用马来酸酐或马来酸酯进行接枝反应来增容。在此方法中塑化、接枝反应、共混在螺杆挤出机中进行，能一次完成，要求螺杆挤出机的螺杆长径比在40左右，中间有排气和加料口，螺杆挤出机可以是单螺杆挤出机也可以是双螺杆挤出机。

It is necessary to pay attention to the compatibility of different polymers in blending modification. When two kinds of polymers with poor compatibility are blended, it is often necessary to add the third component with good compatibility, which is called compatibilizer. The dielectric strength of PP is very high and increases with the increase of temperature. These are beneficial to electrical insulation materials in wet and hot environment. On the other hand, the surface resistance of PP is very high, so antistatic treatment must be carried out in some occasions. The application of PP in the field of industry and life consumption will get more rapid development. The sales volume of PP in China has been about 700000 tons a month. At present, China is one of the largest consumption countries in the world. With the colorful life, more and more PP products make consumers feel the superiority of science.

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。

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.
