FABRIC OVER FOAM GASKETS DTR-WxT XX2xNxxCxx V0-L-ZZZZ

mtc’s triangular profiles have a polyurethan foam core which is covered with a conductive copper-nickel (CuNi) coated fabric. The gaskets are fitted with two non-conductive and one conductive adhesive tape as standard. The standard portfolio includes a large range of sizes. Customized dimensions can be supplied at low cost. The material can also be cut to the required length or modified to individual needs. Fabric over foam gaskets are also available in a halogen free version. Features

Polyurethan foam core; standard hardness value: 45 kg/cm³ Excellent shielding effectiveness Optionally available with adhesive tape with removal aid (WRL) Optionally available with multiple parts on carrier sheet (STP) Large range of standard sizes ; other dimensions on request Also available in a halogeen free version
