Treatment enables PE products to withstand heat to 350°F.

Press Release Summary:

Post-molded crosslinking process enables polyethylene (PE) products to maintain form and strength at temperatures over 350°F. Electron-beam-processed, crosslinked materials can be used in utility services subjected to high temperatures and stress fatigue situations as crosslinking process reduces stress-crack and wear-resistance failures. PE products can be treated after forming by injection molding, rotomolding, or other processes.

Original Press Release:

Low-Cost, Treated Polyethylene Withstands 350°F - Opening New Markets for Temperature-Resistant Plastics

Cranbury, NJ: Standard, low-cost polyethylene (PE) products are upgraded by E-BEAM Services, Inc., in a post-molded crosslinking process (PEX) that is consistent with the performance expectations of more expensive, thermal-set products.

In comparison to standard PE products, which will lose most of their strength and characteristic form at a temperature of about 190°F., the electron beam-processed, crosslinked materials maintain both form and strength at temperatures over 350° F. In addition, the crosslinking process reduces the stress-crack and wear-resistance failures that are problems characteristic of some plastics.

Crosslinked polyethylene products are used in utility services that are subjected to high temperatures and stress fatigue situations. In addition, e-beam crosslinking of polyethylene and ultra high molecular weight (UHMW) materials can improve product wear resistance by several factors.

Standard PE products, attractive for their low cost and low melt points can be formed by injection molding, rotomolding, or other processes and then treated by E-BEAM Services, Inc. to form the post-molded crosslinked product.
