Quality inspection of PP plastic stool
PP plastic generally refers to polypropylene, has good dielectric properties and high frequency insulation, and free from humidity influence, but at low temperature brittle, non wear, easy aging. Suitable for making general mechanical parts, corrosion resistant parts and insulating parts. For this case, you can accurately locate the ingredients and the content of various elements by micro spectral analysis to obtain an exact proportion of the formula. I hope I can help you.
