Read： 376 Time：26months ago Source：

polypropylene is a non-toxic, tasteless, low degree, strength, rigidity, hardness and heat resistance are better than low-pressure polyethylene, can be used at about 100 degrees. It has good electrical properties and high-frequency insulation and is not affected by humidity, but it is brittle at low temperature, not wear-resistant and easy to age. Suitable for making general mechanical parts, corrosion-resistant parts and insulation parts . Common acid and alkali organic solvents have little effect on it and can be used for tableware.
