Polypropylene is a kind of thermoplastic resin, not to mention a kind of resin material. This kind of material has a wide range of uses. We can find it in all the things we wear. Moreover, the annual consumption of polypropylene material is as high as 55 million tons, and this value will rise every year. Moreover, this kind of material has high plasticity, which is very meaningful for environmental protection and can be used repeatedly, Like our common stationery, rope, woven bags, ton bags, plastic parts and other parts can use polypropylene.
Polypropylene and polyethylene are almost the same, especially in solution. Because of the existence of a methyl side chain, it can improve the mechanical properties and heat resistance, but polypropylene is more easily oxidized and degraded under the action of ultraviolet and heat, and has high heat resistance and chemical stability.
In essence, there is little difference, except that the density is a little lower than that of polyethylene, the other aspects are the same, so the present state is translucent. Polypropylene is a non-toxic, odorless, tasteless, milky white, high crystalline polymer, which is the lightest one among the plastic materials at present. Its stability is very stable, whose absorption rate is very low, and its chemical stability is very good, It is often used as a container for storing chemicals, which is why this material can be used on a large scale.
