We deliver rubber insulating mattings that are designed according to the ASTM D178 Standard. This standard is set by the American Society for Testing and Materials. These mattings are considered to be highly electrical resistant. They are non-conductive in nature and are meant to protect and insulate from deadly shocks caused by high voltage equipment. The ASTM D178 Standard endorses a thickness of 3.2 mm to 12.7 mm for these particular mattings. It depends upon the smooth lower surface with the usage/working voltage resistance & anti-skid textured surface on the top. Such safety rubber mattings (Type-1 Grade) are moisture, water & leakage proof that guarantee a long functional (work) life. A Type-2 Grade Insulating Mat contains certain additional properties such as Flame & Ozone resistance. Manufacturer’s Test Certificate is provided along with the supply.
