2、pp塑料具有优良的力学性能，其强度和硬度、弹性都比hdpe高。3、pp塑料具有良好的耐热性，耐寒性不如聚乙烯。4、pp聚丙烯的化学稳定性很好，除能被浓硫酸、浓硝酸侵蚀外，对其它各种化学试剂都比较稳定。5、pp聚丙烯的高频绝缘性能优良，由于它几乎不吸水，故绝缘性能不受湿度的影响。

pp plastic pp pp specific gravity 0.9-0.91 g / cm3 shrinkage1.0-2.5% molding temperature 160-220 °c. the composition andstructure of pp is crystalline polymer, and the density of pp isonly 0.91 g / cm3(smaller than water) . in general purposeplastics, pp has the best heat resistance, its thermal deformationtemperature is 80-100 °c, can be boiled in boiling water. pp has agood resistance to stress cracking, has a high bending fatiguelife, commonly known as "100 fold adhesive. ". the comprehensiveproperties of pp are better than those of pe. pp products light,good toughness, good chemical resistance. disadvantages of pp: lowdimensional accuracy, lack of rigidity, poor weather resistance, ithas the phenomenon of post-shrinkage, demoulding, easy aging,brittle, easy deformation.
