A unique material that permits the passage of air and water vapor yet is impervious to water and dust. An internal pressure regulator <TEMISH>, featuring a fluoroplastic porous membrane with innumerable micropores, is used for the waterproofing/air ventilation of vehicle lights. This unique material also demonstrates high water repellency and heat/chemical/weather resistance. <EPT SEALER>, a multi-purpose sealant, is used to fill various types of gaps in order to insulate against heat, water, sound, or vibration. Highly functional sealing properties have been developed by blending EPDM rubber foam, which offer the best durability and weather resistance among general rubber material, with Nitto Denko’s unique adhesive technology. Superior resistance to heat and chemicals allows stable and consistent performance over long periods of time. A wide range of types are available depending on usage, from flame retardant to soft or high-compression. The superior performance of <EPT SEALER> is recognized by various domestic and international industries, and is used in automotive, housing, and home appliance areas.
