The characteristic of the PP melt-brown fabric

Polypropylene (PP melt blown fabric), a plastic, is a linear polymer with high density, no side chain and high crystallization, which has excellent comprehensive properties. Common products: basin, barrel, furniture, film, woven bag, bottle cap, automobile bumper, etc.

PP plastic (PP melt blown fabric), chemical name: polypropylene, English Name: polypropylene (hereinafter referred to as PP) specific gravity: 0.9-0.91 g / cubic centimeter, molding shrinkage: 1.0-2.5%, molding temperature: 160-220 ℃, PP is a crystalline polymer, and the comprehensive properties of PP are better than PE. PP products have light weight, good toughness and good chemical resistance. Disadvantages of PP: low dimensional accuracy, insufficient rigidity and poor weather resistance. It has post shrinkage phenomenon. After demoulding, it is easy to age, become brittle and deform（PP melt blown fabric).
