Are you having problems with water sealing using caulking (sealing)? By replacing caulking with a durable rubber packing, you can achieve quantitative water sealing!
Is there a decrease in water-stopping functionality due to a shortage of craftsmen or lack of experience in caulking, leading to water-stopping complaints? We propose the possibility of achieving caulking-free solutions by converting part of the on-site caulking to rubber packing. Additionally, by using sponge rubber that incorporates a high resilience feature of "not deforming," we can significantly reduce the frequency of caulking reapplication. The EPDM, which is the raw material for rubber sponge, possesses excellent chemical resistance, cold resistance, ozone resistance, and aging resistance. By adding the characteristic of "not deforming" to the inherent elasticity of sponge rubber, it eliminates the need for replacement due to deformation. Furthermore, by developing this concept, it can also be utilized as a "damper material" by leveraging a certain load response. - Features - - High weather resistance due to 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) * Can be cut to the required length and delivered with adhesive tape - Instantly restores from a compressed state - High shape retention - Extremely low permanent deformation strain - Soft sponge suitable for a wide range of applications

basic information
It is possible to deliver rubber sponge manufactured by extrusion molding with double-sided tape attached. - SSF: Standard hardness SSF, hardness 20 - SSF-HARD: For areas where particularly high airtightness is required, hardness 30 - SSF-PO: For areas where issues arise due to free sulfur, hardness 15 - SSF-CR: For areas requiring flame retardancy and oil resistance, hardness 20 - SSF-SOFT: For areas that require water sealing with small stress, hardness 2
Price information
Prices vary based on quantity. We can offer a cost difference of about 10-20% compared to standard EPDM. *Basically, the materials are the same, and the "non-sagging" function is achieved through differences in manufacturing methods.

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.
