Has good dielectric properties
Apr 28, 2018

Non-toxic, odorless, low density, strength, stiffness, hardness, heat resistance are better than low-pressure polyethylene, can be used around 100 °C. Has good dielectric properties and high frequency insulation and is not affected by humidity, but becomes brittle at low temperatures, not wear and aging. 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 as food utensils.

Polypropylene has many excellent features:

1, the relative density is small, only 0.89-0.91, is one of the lightest varieties of plastic.

2, good mechanical properties, in addition to impact resistance, other mechanical properties are better than polyethylene, molding process performance is good.

3, with high heat resistance, continuous use temperature up to 110-120 °C.

4, good chemical properties, almost no water absorption, and most chemical products do not react.

5, pure texture, non-toxic.

6, good electrical insulation.

7. The transparency of polypropylene products is better than that of high-density polyethylene products.
