The characteristics of pp
Non-toxic, tasteless, small density, strength, stiffness, are better than that of low pressure polyethylene, hardness and heat resistance can be used at about 100 ¡æ.Has good performance and high insulation and is not affected by humidity, but low temperature time-varying crisp, wear-resisting, easy to aging.Suitable for making general machinery parts, corrosion parts and insulation parts.Common acid, alkali and other organic solvents almost had no effect on it, it can be used in tableware.
Polypropylene has many excellent features:
1, the relative density is small, only 0.89-0.91, is one of the lightest varieties of plastics.
2, good mechanics performance, in addition to the resistance to impact and other mechanical properties are better than polyethylene, processing performance is good.
3, has higher heat resistance, continuous use temperature can reach 110-110 ¡æ.
4, chemical performance is good, almost no water absorption, and does not react with most chemicals.
5, texture, pure, non-toxic.
6, good electrical insulation.
7, the transparence of polypropylene products better than transparency of high density polyethylene products.
