A damper material that utilizes the "non-deforming" characteristics and elasticity of high-recovery rubber, which can almost eliminate permanent deformation even with long-term use. Proven in mass-produced vehicles!
Long-term use of sponge rubber, which tends to "flatten out," required regular replacement, but high resilience rubber sponge does not "flatten" even with long-term use. Utilizing the inherent elasticity of sponge rubber along with the characteristic of "not flattening" and a certain load response, it can be used as a "damping material." High resilience rubber sponge has an extremely small permanent deformation strain, making it excellent in shape retention, and it instantly returns to its original shape even after being released from a state of continuous pressure over a long period. - Features - ・Instant recovery from a compressed state ・High shape retention ・Extremely small permanent deformation strain ・Soft sponge suitable for a wide range of applications ・High weather resistance with EPDM (ethylene propylene rubber) ・Operating temperature range -20 to +80°C ・Sulfur-free grade with free sulfur measured below the detection limit ・Flame retardant/oil resistant grade (railway flame retardant compliant) *Custom cutting to required lengths is available, and delivery can include adhesive tape.

Company information
Founded 91 years ago as "Yashima Automobile Parts Trading Company," our company originated from the automotive parts division of Yashima Motor Co., which was the general importer of Chrysler vehicles in 1926. Over the years, we evolved from supplying repair parts to directly providing mass-produced components to automobile manufacturers, in line with the pre-war and post-war trends of domestic automobile production. At the time of our establishment, the Toranomon area was referred to as Japan's Detroit, yet there were almost no domestic vehicles present, and we had been engaged in automotive-related business even before the domestic production of automobiles began. Today, we have transformed and grown into a technical trading company that directly supplies and sells mass-produced parts to major automobile manufacturers and construction machinery manufacturers. We support the development departments of manufacturers with technical proposals and assist the procurement departments with global parts sourcing, providing mass production solutions for a wide range of products, from resin molded products, semiconductors, electronic components, and sensors to inverters and onboard motors that make up electric vehicles. Notably, the next-generation onboard electrification components have significantly increased, with mass production sales reaching an annual scale of 6 billion yen.
