EPDM rubber sealing material "Eptsealer" EH-2200 series

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?** Eptsealer is a foam created through Nitto's unique foaming technology, featuring a semi-continuous and semi-independent foaming structure. In addition to sealing applications that leverage its 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 options. It is used in various fields such as automobiles, housing, and home appliances. Composed mainly of EPDM rubber, it possesses excellent properties among general-purpose rubbers, including heat resistance and chemical resistance (to acids and alkalis). **About the EH-2200 Series** The EH-2200 series 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 raises concerns about metal corrosion. By not using sulfur, it retains the properties 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 that are becoming smaller, without corroding metals, for cushioning, soundproofing, and dustproofing applications. At Nitto Elmaterial, we respond to customer requests by utilizing a network of diverse processing companies to accommodate a wide range of processing needs.

Product HP

basic information

■Features - Excellent resistance to metal corrosion due to sulfur-free formulation. - Can be easily compressed due to low stress during compression, conforming well to the unevenness of the substrate. This effect provides excellent airtightness and soundproofing. - Superior durability, weather resistance, heat resistance, and chemical resistance. - Complies with UL94 HBF standards and has flame retardant (slow burning) properties. - The foam layer is UL-94HBF flame retardant certified. (Scope of application complies with the Yellow Card) ■Standard Size Thickness (mm): 3–20 (with adhesive 3–25) Width (mm): 900 Length: 2
