Full definition
A conveyor belt with covers made from nitrile rubber (NBR), chloroprene (CR/neoprene), or specialized blends designed to resist swelling, softening, and degradation from contact with mineral oils, vegetable oils, greases, and hydrocarbons. Classification per ISO 14890: MOR (moderate oil resistance — for animal fats, vegetable oils), MORV (severe oil resistance — for mineral oils and fuels). Testing: immersion in ASTM Oil No. 1 and No. 3 at elevated temperature, measuring volume swell and tensile loss. Nitrile covers (ACN content 30-40%) offer the best resistance to petroleum-based oils. Neoprene covers are preferred when combined oil and flame resistance is needed. Applications: oilseed processing, recycling centers, metalworking chip conveyors, food processing, steelworks, and ports handling oily cargoes. Also available with FDA-compliant white nitrile covers for food contact. Per DIN 22102 and ISO 14890. Top cover: 2-6 mm. Brands: Continental, Fenner Dunlop, Habasit, Forbo.
