Superior chemstop terry-lined heavy-duty neoprene gloves feature acrylic terry lining for thermal insulation. Diamond-grip finish on palms for increased wet/dry grip. Neoprene, DuPont's trade name for chloroprene, was the first commercial synthetic rubber created. It has good abrasion, cut and even heat resistance, which makes it a great choice for working in both the food industry (deep fryers) and the petrochemical industry, with heat stability up to 200 degree F. This makes gloves suited to hot/cold liquid applications as well, perfect for steam applications like autoclaves or any situation where intermittent contact up to 400 degree F occurs. (The time to pain at 392 degree F is 16 seconds. Not recommended for use above 500 degree F.) Note: gloves will tolerate brief exposure to flame, but are not recommended for use around open flame. Neoprene resists the effects of aging, sunlight, ozone, oxidation and weather, as well as a broad range of oils and chemicals that attack natural rubber gloves like acids, caustics, oils, grease, and many solvents. Applications include chemical processing, commercial fishing, food processing, general industry, oil refineries, petrochemical, degreasing, refining, plating and galvanizing.
