Developed the world’s first electron beam-crosslinked closed cell foam, in our laboratory.
Softlon is closed cell physically cross-linked polyolefin foam products
- SOFTLON is a closed-cell, physically cross-linked polyolefin foam developed and commercialized by Sekisui Chemical Group. Utilizing proprietary electron beam irradiation technology, this process induces cross-linking at the molecularlevel without the use of chemical cross-linking agents, resulting in a cleaner and more environmentally friendly production method.
- The advanced cross-linking technique produces a uniform, superfine cell structure that significantly enhances the material’s mechanical strength, thermal insulation, dimensional stability, and chemical resistance. These properties make SOFTLON ideal for high-performance applications across automotive, electronics, construction, and other industrial sectors.”
