Some manufacturers use a combination of materials to produce heavy-duty gloves which provide even greater user protection.
Some of the common natural materials used include variations of deerskin and cowhide leather and, for additional insulation, lining material, such as sheepskin. A durable material, leather gloves excellent gripping characteristics, as well as resist moderate heat, sparking, and cuts from sharp or abrasive materials.
Gloves produced from a combination of natural and synthetic rubbers and leather material are effective in preventing shock and burns from electrical contact. Specifically, these rubber gloves may contain leather protectors and cuffs and be lined with insulating wool and thermal materials. These electrical gloves are typically OSHA-compliant and are considered either ozone resistant or non-ozone resistant. Both variants should be electrically tested before use and regularly after use. Some of the typical applications and processes that require these gloves include plant and facility procedures, and power utility maintenance.
