Crosslinked materials.

Plastic tubing and molded parts are processed by the company to create a permanently crosslinked molecular structure that is said to exhibit outstanding performance reliability. long wear, and temperature and chemical resistant characteristics for use in automotive under-the-hood applications. The company treats tubing and molded components and assemblies using an environmentally responsible high energy process that permanently alters the polymeric matrix by converting the material to a crosslinked PE, known as PEX. During the processing, high-energy electrons penetrate the product to form three-dimensional molecular links that are said to deliver a wide variety of commercially desirable properties. Automotive design engineers can use this crosslinking process on HDPE tubing and molded parts to provide in-service temperatures as high as 120[degrees]C. In comparison, untreated HDPE tubing normally withstands in-service temperatures of about 60[degrees]C. In addition to improving performance temperatures, the process is also said to provide increased thermal stability under load, according to the company. (E-Beam Services)
