Crosslinked polyethylene as a high-performance barrier material

Overview

Crosslinked polyethylene (PE) represents a significant advancement in barrier materials due to its unique three-dimensional network structure. Unlike traditional PE, which features a linear chain, crosslinked PE involves chemically bonding the polymer chains through an activated radical process. This innovation results in a material that is exceptionally resistant to gases, liquids, and a wide range of chemicals, including acids, alkalis, and solvents. The crosslinked network effectively minimizes permeability, making it an ideal choice for applications requiring reliable and durable barriers.

Technical specifications

Key features:

• Chemically bonded three-dimensional network structure
• Exceptional resistance to gases and liquids
• High chemical resistance, including acids, alkalis, and solvents
• Enhanced durability and integrity in harsh environments

The crosslinking process creates a robust barrier that prevents molecular movement through the material, offering superior protection against permeants. This makes crosslinked PE suitable for industries such as chemical processing, packaging, and any application where exposure to harsh chemicals is a concern.

Technology readiness level

This technology is currently at Technology Readiness Level 4, indicating that the crosslinked PE has been validated in a laboratory setting. Future steps involve synthesizing the functional crosslinkable PE material, creating films, and testing their barrier performance for targeted applications, followed by optimization.
