Sponge packing wear prevention measures
Are you experiencing issues with water sealing or airtightness due to the wear of sponge rubber packing? There is almost no wear even after long-term use (10 years)!
This is a sponge rubber made of EPDM with the added feature of high resilience that does not deform easily. When used as airtight seals for equipment handling powders or waterproof seals for liquids, it exhibits extremely low compression deformation even over long periods, preventing the seals from wearing out. For example, it significantly reduces the frequency of seal replacements in areas with poor maintenance accessibility. By incorporating the inherent chemical resistance, cold resistance, ozone resistance, and aging resistance of EPDM, along with the "non-deforming" characteristic of sponge rubber, it eliminates the need for replacements due to wear. Additionally, by further developing this concept, it can also be utilized as a "damping material" by leveraging its consistent load response. - Features - - High weather resistance with EPDM (ethylene propylene rubber) - Operating temperature range: -20 to +80°C - Sulfur-free grade with free sulfur below measurement limits - Flame retardant/oil resistant grade (railway flame retardant compliant) * Custom cutting to required lengths available, with adhesive tape for delivery - Instant recovery from a compressed state - High shape retention - Extremely low permanent deformation - Soft sponge suitable for a wide range of applications
basic information
☆Product lineup tailored to applications - SSF: Standard hardness SSF, hardness 20 - SSF-HARD: For areas requiring particularly high airtightness, 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 under small stress, hardness 2
Price information
Prices vary depending on the quantity. We can offer it at 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 the manufacturing process.

Applications/Examples of results
Examples utilizing the concept of "not losing shape": - Seals for equipment that are difficult to replace after installation in mountainous or remote areas - Seals for parts integrated within equipment that are not easily replaceable - Electrical boxes and distribution boards that lose waterproofing due to deformation (Waterproofing) - Seals for tsunami barrier doors - Seals for bathroom fixtures in residential settings (apron water stops, drainage channels, inspection openings, etc.) - Seals for various industrial equipment (Airtightness) - Odor dispersion prevention - Paper dust dispersion prevention - Airtight seals around doors (Rubber dampers utilizing the elasticity of rubber sponge) - Automotive hood dampers
