Super Set Form: SSF is a high-recovery rubber sponge that brings permanent deformation close to zero. It returns instantly, with extremely small permanent deformation and excellent shape retention. Due to its outstanding high recovery, it is ideal for packing materials in areas requiring high airtightness, contact parts that are opened and closed repeatedly, and gasket materials needed for long-term sealing. - Tsunami countermeasure partition door packing - Bathroom packing for residential equipment (apron water stop, drainage, inspection openings, etc.) - Airtight parts for various industrial equipment

This is a high-recovery rubber sponge that brings the permanent deformation of sponge rubber as close to zero as possible. When released from a state of continuous pressure after long-term use, it instantly returns to its original shape, with extremely small permanent deformation and excellent shape retention. Due to its excellent recovery properties, it is suitable for packing materials in outdoor equipment that require water tightness, as well as gaskets in areas where long-term water tightness is necessary and where parts are repeatedly opened and closed. It is particularly suitable for waterproof packing in remote equipment that cannot be frequently replaced, as well as packing inside devices that are not easy to replace. Additionally, it has been successfully used for applications requiring airtightness, such as odor prevention in portable toilets, prevention of paper dust scattering, and airtightness around doors.

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.

Four Strengths - Functionality equivalent to petroleum-based plastics - A first step towards reducing plastic usage - CO2 emission reduction effect - Low cost [Functionality equivalent to petroleum-based plastics] It has moldability, convenience, strength, and quality comparable to petroleum-derived plastics, offering similar functionality. [A first step towards reducing plastic usage] With a biomass content of 25%, it reduces the use of finite petroleum-derived plastics by 25%, serving as a first step towards environmental measures and reducing plastic usage. [CO2 emission reduction effect] In Japan, waste disposal is primarily through incineration, including plastics. Incineration results in CO2 emissions, which are a significant environmental issue. This cushioning material reduces CO2 emissions during combustion by approximately 25% compared to plastic (PP), as verified by CERI (Chemical Evaluation and Research Institute). The reduction effect is recognized, rather than just theoretical carbon neutrality. [Low cost] In terms of cost, it is about 1.5 times that of plastic (PP), making it cheaper than bioplastics.

Plastic magnets (bond magnets) used in automotive steering and switch areas, which incorporate magnetic sensors, are easier to handle, lightweight, and less affected by rust compared to metal sintered magnets, making them excellent in properties. The base resin materials can be selected according to applications and needs, including nylon-based and PPS, and complex shapes can be molded through insert molding and two-color molding. We can accommodate multipole magnetization and radial magnetization, providing comprehensive proposals for materials, properties, and shapes, and we will mass-produce them in domestic lines with proven mass production results.

As a bio-based and biodegradable resin material, it is developed and patented by a Hong Kong capital company. It has a production capacity of 10,000 tons per year and a material development system located in Zhuhai, Guangdong Province, China, with a track record of 10 years since production began. The plants used as raw materials are non-GMO, ultra-high molecular weight, and have a low MFR, making them safe for applications that come into direct contact with food due to the absence of harmful additives. The bio-based content certified by the U.S. certification body BETA is up to 52%. It is 100% biodegradable and is currently applying for the European standard "EN13432." Biodegradable sheet for thermoforming VS-60-1-B is over 70% biodegradable and complies with China's recommended national standard "GB/T 20197-2006." The plants used as raw materials are non-GMO, and the bio-based content certified by the U.S. certification body BETA is up to 81%. It is safe for applications that come into direct contact with food (RoHS, REACH testing completed). High-quality molding can be achieved with standard plastic processing equipment.

In addition to the protective performance of FRP and epoxy used for resin lining aimed at surface protection of machinery, it enhances explosion resistance, abrasion resistance, impact resistance, and chemical resistance. In harsh environments where various deterioration factors such as severe wear on construction machinery bodies, buckets, and shovels, the vulnerability of hardened tools to cracking, corrosion from chemicals and salt in coastal areas, and thermal effects are compounded, applying a polyurea resin lining to the surface will continue to protect the base part for a long time. According to JIS standards, the paint wear test shows a coating loss of 3mg after testing, demonstrating significantly higher abrasion resistance compared to other lining materials, and it maintains stable strength outdoors for an extended period due to its high weather resistance. By applying polyurea coating to particularly deteriorated parts such as bulldozer buckets, shovel sections, conveyor systems, and agricultural tillage and cutting blades, an extension of the deterioration lifespan is expected. In practical applications on snowplow shovels, it has shown significant effects in abrasion resistance and resistance to calcium chloride, and in high-grade materials with excellent chemical resistance, it has long-term resistance to 50% sulfuric acid, protecting the substrate from corrosion factors (acids, alkalis, etc.).

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
