Physiologically inert, associates a good combination of rigidity, toughness and resilience. It has good chemical resistance and can be easily welded. PE-HD is a versatile polyethylene used primarily in the food industry, as well as in the chemical, mechanical and electrical industries. This material can be obtained by extrusion (E) or by pressing (P). The use of pressed polyethylene is suggested in machined parts and in all applications in need of a better dimensional stability. They are easily distinguishable by their surface, in the case of PE-HD / E, it presents the different faces (1 matte and 1 glossy). In the case of PE-HD / P, the faces are the same with rectified appearance.
