Available formats: Bars, Tubes, and Plates

features

The PE 500 known as PE HMW, offers good resistance to wear and abrasion, along with a good combination of stiffness, toughness and strength, as well as being easily welded just like its other versions such as PE 300. Its main utility is in the food industry, in addition to all kinds of mechanical applications, in the chemical industry and in the electrical industry.

 

Polyethylene (PE) is chemically the simplest polymer and is represented by its repetitive unit (CH2-CH2) n. It is one of the most common plastics due to its low price and simplicity in its manufacture, which generates an annual production of approximately 80 million tons worldwide. It is chemically inert and is obtained from the polymerization of ethylene, from which its name derives.

 

This polymer can be produced by different polymerization reactions, such as: Free radical polymerization, anionic polymerization, ion coordination polymerization or cationic polymerization. Each of these reaction mechanisms produces a different type of polyethylene.

Applications

PE 500 or PE HMW is often used for chain guides, wear bands, gears and wear plates in silos, where the desire is low friction.

 

PE 500 offers greater wear resistance and impact resistance compared to PE 300. It is extremely strong, has excellent resistance to chemicals and low temperatures and has very low moisture absorption.

 

It is used in applications such as tampons, cutting boards, replacement or replacement of parts and protective strips.

The data shown in this table have been determined in our laboratories and should only be considered as a useful reference; They did not commit for us in the different forms of application. As a result of our technological experience and our best knowledge, the data offers an initial evaluation of the polymer. This data cannot be applied to finished parts as obtained under specific conditions and is only an average value. Values should be considered a useful reference and are given without compromise.
