Material of the Month: Cross Linked Polyethylene (XLPE)

Lightweight, Versatile, Durable: A High Performance Foam Solution

This blog is the second in a new CGR Products content series titled “Material of the Month.” The series will spotlight some of the unique materials and their applications that CGR works with.

High performance material choices can make all the difference in a project. From sheet rubber to open- and closed-cell foam to adhesive solutions, our Material of the Month series will spotlight some of these unique materials and their applications.

For this post, we’ll be featuring cross linked polyethylene. This flexible, closed-cell foam has low water absorption and excellent thermal insulation properties.

The foam material also makes it highly efficient for conversion into various shapes — including Christmas trees and snowflakes, as pictured in the photo!

What is Cross Linked Polyethylene?

XLPE is a smooth, fine-celled foam with exceptional consistency and gauge control. It presents superior physical and chemical properties, including low vapor transmission and water absorption. XLPE is available in  many grades.

Benefits and Uses

Foam rubber has cushioning properties to lessen impact and smoothly fill voids and gaps between less flexible materials. Closed-cell foams such as  XLPE are especially useful as seals, reducing the flow of gases and other liquids.  XLPE is particularly effective in transportation industry watershields, healthcare devices, and industrial cap seals because of its low water absorption.

Other uses of  XLPE include:

• Instrument panels and door panels for the transportation industry
• Medical tape and transdermal drug delivery
• Industrial tape and specialized packaging
• Appliance and vehicle gaskets
• Construction
• Military and defense
• Sports paddings and new technology

Nontoxic and free of CFC, HCFC, and hydrocarbon blowing agents,  XLPE is available for conversion from both seamless rolls and laminated sheets. Each grade of  XLPE offers its own unique environmental and physical performance perks — consult one of our materials experts to find the best fit for your project.

Custom Fabrication at CGR

Foam materials are an ideal option for many industries and are a highly efficient material for cutting and conversion work at CGR. Our team can hold standard RMA tolerances to create foam rubber gaskets, sealants, and custom parts.

Our precision die cutting services, including both rotary and flatbed die cutting, as well as knife cutting and waterjet cutting, can deliver extremely precise, ready to use foam components.
