Non-toxic, tasteless, low density, better strength, rigidity, hardness and heat resistance than low-pressure polyethylene, and can be used at about 100 degree. Good electrical performance, high-frequency insulation, not affected by humidity, but fragile, not wear-resistant, easy to age at low temperature. Suitable for making general mechanical parts, corrosion-resistant parts and insulating parts. Common acid-base organic solvents have little effect on it and can be used for tableware.
