16” CPE Shoe covers are made of Compressed Polyethylene (CPE) Film, commonly called Polylatex, is made from a mixture of 65% Low Density Polyethylene (LDPE) and 35% Light Low-Density Polyethylene (LLDPE). Polylatex film is very lightweight and is a complex hydrocarbon chain. It is practically impervious; hence it is excellent for containing moisture and dirt. It also repels moisture and oil. Polylatex is non-toxic and odorless. Polylatex has excellent resistance to chemical corrosion and its physical properties are not affected by either chemical or solvents. Since it is a form of plastic material, it possesses excellent strength and it can be easily sealed. It is heavily textured for better grip.
