Description: ENSOLITE IV2 closed cell sponge is a blend of PVC/Nitrile/Neoprene polymers to provide optimum characteristics for gasketing or sealing applications. IV2 is a long accepted material for indoor and outdoor uses requiring a temperature range of -40°F to +200° F.
IV2 is rated as 2B2 under ASTM D1056-07. This is a good rating for oil resistance in ASTM D1056 and allows IV2 to be used where other materials might swell and upset functionality. IV2 is listed as meeting the UL94 V-0, V-1 and HF-1 flammability ratings and the FMVSS-302 rating. These ratings and good chemical resistance allow IV2 ENSOLITE to be used in many industrial, OEM, transportation and automotive applications. It is also listed to UL 50E.
ENSOLITE IV2 closed cell PVC/Nitrile/Neoprene sponge is a soft/medium density material. Other grades are IV1 (soft density), and IV3 (medium density). All ENSOLITE products can be supplied with or without adhesive backing in full rolls up to 54" wide, or slit rolls as narrow as ¼" or we can die cut or waterjet cut parts to your exact specifications.
