1mm Durable IXPE Cross Linked PE Foam Low Density Closed Cell Insulation Sheets
1mm IXPE (Irradiated Cross-Linked Polyethylene) Foam represents the pinnacle of thin-gauge foam technology. Unlike standard polyethylene foams (EPE or XPE), IXPE undergoes a high-energy electron beam irradiation process. This molecular cross-linking creates a tight, three-dimensional physical structure that remains incredibly durable even at a thickness of only 1mm. Designed for high-performance sealing, thermal insulation, and vibration damping, this low-density, closed-cell material is the preferred choice for industries where space is limited but performance cannot be compromised. Its smooth, skin-like surface is specifically optimized for Pressure Sensitive Adhesive (PSA) lamination, ensuring a permanent bond in demanding environments.

Frequently Asked Questions
How can I determine the suitable foam density I need?
Our PE foam density ranges between 25 kg/m³ and 330 kg/m³. We can provide the best solution for you according to your application requirements, including density, hardness, and thickness specifications. Free samples are available for your confirmation and testing.
What's the difference between open and closed cell foam?
Insulation foam is categorized as open cell or closed cell based on the structure of the small bubbles (cells) that make up the foam. In closed cell foam, the cells are pressed together, preventing air and moisture from penetrating the material. This structure makes closed cell foam much more rigid and stable than open cell foam.
What applications could XPE and IXPE foam be used for?
XPE and IXPE foam have numerous applications across various industries including: Automotive NVH (Noise, Vibration, and Harshness) control; PE foam tape manufacturing; Building insulation systems; HVAC insulation; Electronic component protection; Sports protective equipment; Flooring underlayment; and many other industrial applications.
