Plastic Profiles out of Polyethylen – PE

Polyethylene belongs to the semi-crystalline plastics and the family of polyolefins. PE is the most commonly used type of plastic. It combines many advantageous characteristics such as high chemical resistance, good electrical insulation properties and good sliding properties. A special feature is that polyethylene is resistant to water and can be used for applications in connection with food. In addition, it should be emphasized that polyethylene is lightweight and can be processed at comparatively low temperatures. This lowers energy consumption in processing and is good for the environment. Furthermore, it can also be recycled very easily.

PE differentiates many different plastic variants, but is generally plasticizer-free and physiologically harmless. The main distinction is between LDPE and HDPE.

LDPE (low density polyethylene) is a very soft and flexible material. It has high impact strength and good chemical resistance. It is also softer and the yield strength is higher than that of HD-PE. Because of these characteristics, plastic profiles and pipes are used for thin and very thin wall applications. LLDPE (linear low density polyethylene) is closely related to low density polyethylene.

HDPE (high density polyethylene) stands out because of its high toughness and good chemical resistance. Due to its high tensile strength and stability, HDPE can be used especially for plastic profiles, pipes and hoses.

PE-80 and PE-100 are mainly used for heating pipes and drinking water pipes.

Binder + Wöhrle processes polyethylene both in the field of plastic extrusion and plastic injection molding. B + W has many different types in use and produces in the diameter range of 0.5 – 50 mm customized plastic pipes, hoses -profiles, -sheathings, ¬connections and much more.
