The polypropylene in the plastic clip is non-toxic, odorless, low-density, strength, rigidity, hardness and heat resistance are better than low-pressure polyethylene, and can be used at about 100°C. It has good dielectric properties and high-frequency insulation and is not affected by humidity, but it becomes brittle at low temperatures, not wear-resistant, and easy to age. Suitable for making general mechanical parts, corrosion-resistant parts and insulating parts. Common organic solvents such as acids and alkalis have little effect on it and can be used for food utensils.
Polypropylene in plastic clips has many excellent properties:
