The history of polyethylene dates back to 1898 when Von Pechmann obtained a polymer with a structure equivalent to polyethylene called polymethylene.

Characteristics of the Materials Used by Roymaplast High Density Polyethylene (PE-HD): In addition to its excellent processability, PE-HD appeals for its high chemical resistance and its firmness and stiffness in the temperature range from - 50ºC to + 80ºC.

Polymeric materials (PLASTICS) Artificial materials derived from organic chemistry. They are made up of long-chain molecules, called monomers or groupers, chemically linked by covalent and ionic bonds.
