 成形特点：

（1）工艺性能：pp为***、无气味的奶白色高结晶体的高聚物，是现阶段全部塑胶中为轻的种类之一，对水非常平稳，在水中14h的吸水性仅为0.01%。相对分子质量约8~15万中间，成形性好。但因缩水率大，原壁产品易凹痕，产品表层光泽度好，便于上色。

（2）物理性能：pp的晶粒大小高，构造整齐，因此具备优质的物理性能，其抗压强度和强度、延展性都比密度高的pe(hdpe)高。突显特性是抗弯折疲惫性（7×10^7）次启闭的折选弯折而无毁坏印痕，干摩擦阻力与涤纶类似，但在油润化下比不上涤纶。

(3) thermalproperties: pp has excellent heat resistance, the melting point is164 ~ 170 °c, and the product can be sterilized above 100 °c. itdoes not deform at 150 °c under the action of external force.embrittlement to-35 °c, in less than-35 °c will produce aging. (4)organic chemical reliability: pp has excellent organic chemicalreliability, except that it can be corroded by sulfuric acid andconcentrated sulfuric acid, it is relatively stable to all kinds ofother chemicals, but low molecular weight aliphatic hydrocarbon andaliphatic hydrocarbon can soften and solubilize pp, and thereliability of organic chemistry increases with the increase ofcrystal size. therefore, pp suitable for russia-china chemicalpipeline and spare parts, corrosion-resistant actual effect isexcellent. (5) electrical properties: the high frequency dielectricstrength of polypropylene is of good because it is almostnon-hygroscopic, so the dielectric strength can not be harmed byenvironmental humidity, has a high polarization index and increaseswith temperature, can be used to make heating electrical en layer products, breakdown field is also very high, canbe used as electrical accessories. resistance to working voltage,resistance to electric isolation, but the electrostaticsensitivity, and copper contact brittle. (6) anti-aging:polypropylene is very sensitive to ultraviolet light, adding activezinc oxide diallyl thiopropionate, carbon black type of similarwhite filler can improve its anti-aging properties.
