ISO 14644-7 Access Devices – Glove Materiala) Latex, natural rubber or cis-1,4-polyisoprene• Latex, natural rubber or cis-1,4-polyisoprene is suitable in cases where great flexibility and goodmechanical properties are necessary. However, latex articles are not impermeable to gas, perishin ozone, offer no resistance to flame, hydrocarbons and oxidising salts and poor resistance toesters, acids and bases. The potential of life-threatening allergic reactions should be considered.b) Polychloroprene or 2-chloro-1,3-butadiene• Polychloroprene or 2-chloro-1,3-butadiene is especially recommended when good resistance tooils and greases is needed. This chloroprene is self extinguishing, i.e. when the source of ignitionis removed it no longer continues to burn. Polychloroprene is highly resistant to ozone, ultravioletlight, concentrated acids and bases, and strong oxidising agents. Polychloroprene articles areunsuitable for work with hydrocarbons, halogens and esters.c) Nitrile or copolymer of butadiene and acrylonitrile• Nitrile or copolymer of butadiene and acrylonitrile is recommended when good resistance tosolvents is required. Nitrile articles stand up well to aliphatic hydrocarbons and hydroxylcompounds.d) Polyvinyl chloride• Although plastic, polyvinyl chloride has a certain elasticity and is recommended for its goodelectrical properties and resistance to chemical agents.e) Chlorosulfonated polyethylene• Chlorosulfonated polyethylene offers very good resistance to H2O2, and its white colour allowsgood visual inspection. Other materials are resistant to H2O2, as well.24
