ARONKASEI CO., LTD. Elastomer Dept. Product Lineup

Our foam elastomer coating method is a sealing molding technology that applies foam elastomer from a nozzle. It does not require pretreatment or post-treatment processes such as primer treatment or curing, and can accommodate various shapes of workpieces. We provide a comprehensive proposal from material selection to optimal line design.

The E series is a grade that excels in cold resistance, ozone resistance, and flow characteristics. It also has excellent resistance to alkaline inorganic chemicals and can be made lighter compared to cross-linked rubber. With the exception of some grades, it can be integrally molded with polar resins such as PC and PET-G. It achieves a balance of rubber elasticity and high mechanical strength, demonstrating excellent resistance to bending fatigue, oil resistance, and rebound elasticity.
