Chemical invariance

The chemical invariance of polypropylene(Non Woven Polypropylene Company) isvery good. In addition to being attacked by concentrated sulfuric acid andconcentrated nitric acid, it can keep the same for other chemical reagents.However, low molecular weight aliphatic hydrocarbons, aromatic hydrocarbons andchlorinated hydrocarbons can make polypropylene. It softens and swells, and itschemical invariability progresses with the increase of crystallinity.Therefore, polypropylene is suitable for the construction of various chemicalpipes and fittings to prevent erosion.

Electrical performance

It has a high dielectric constant and canbe used to build heated electrical insulation products(Polypropylene Fabric On Sales) as temperature rises.Its breakdown voltage is also very high, and it is used as an electricalaccessory. It has good resistance to voltage and arc resistance, but it hashigh static electricity and is easy to age with copper.

Weather resistance

Polypropylene(polypropylene non woven fabric factory) is very sensitive toultraviolet light, and it can improve its aging resistance by inserting zincoxide, sec-valerate, carbaryl or similar white filler.
