A foam sealing material that retains the properties of EPDM rubber-based sealants while preventing metal corrosion. Ept is highly compressible and suitable for soundproofing as well.
**What is Eptsealer?** It is a foam created by Nitto's unique foaming technology, featuring a semi-continuous and semi-independent foaming structure. In addition to seal applications that utilize the foaming structure, it can be used for a wide range of purposes such as shock absorption and thermal insulation. We offer a rich lineup that can be differentiated based on applications, including flame retardant, soft, and high-foaming types. It is used in various fields such as automobiles, housing, and home appliances. The main component is EPDM rubber, which possesses excellent properties among general-purpose rubbers, including heat resistance and chemical resistance (acid and alkali). **About the EH-2200 Series** This is a standard sealing material of a semi-independent and semi-continuous type made from foamed EPDM rubber. It is a clean foam that does not contain sulfur, which is commonly used in rubber crosslinking and poses a risk of metal corrosion. By not using sulfur, it retains the characteristics of EPDM while reducing the risk of corrosion to metals (such as copper wires on electronic circuit boards). It can be used in high-sealing electronic devices, which are becoming smaller in recent years, for cushioning, soundproofing, and dustproofing without corroding metals. Nitto Elmaterial responds to customer requests by utilizing a network of diverse processing companies, accommodating a wide range of processing needs.
