Polyethylene is one of the first materials used in thermoplastic powder coatings, and polypropylene is the two most important thermoplastic polymers of the last century. At present, both high density and low density polyethylene are used in the thermoplastic field, usually high density polyethylene is used in the industrial field, and low density is used in the civil field.
Because the molecular chains of polyethylene and polypropylene are carbon-carbon bonds, both have the non-polar characteristics of olefin, so polyethylene and polypropylene powder have good chemical resistance, so it is widely used in the field of corrosion protection, as the protection, storage and transport of chemicals, chemical reagents containers, pipes and oil pipelines
