Non-toxic, tasteless, small degree, strength, stiffness, hardness and heat resistance are better than low-voltage polyethylene, and can be used at about 100 degrees. It has good electrical properties and high-frequency insulation and is not affected by humidity, but it becomes brittle, wear-resistant and easy to age at low temperatures. It is suitable for making general mechanical parts, corrosion-resistant parts and insulating parts. Common acid and alkali organic solvents have little effect on it and can be used in tableware.
