The insulating rubber sheet is made of hydroxyl methacrylate silica gel as the base glue, adding various fillers (hardener, high temperature resistant agent, modified materials, etc.) through the production process of rubber mixing, thin pass, filtering, sulfur addition, die pressing, extrusion, bonding, etc. The insulating rubber sheet has the following characteristics:
(1) High and low temperature resistance: it can be used for a long time at 200 ℃, but it still has ductility at - 60 ℃;
(2) Insulation performance: the dielectric property of the insulation pad is very good, especially the dielectric property at high temperature greatly exceeds that of ordinary organic chemical vulcanized rubber, and the volume resistivity is almost not affected by temperature in the range of 20-200 ℃.
(3) It has the properties of weather resistance, reactive oxygen species resistance and ultraviolet radiation resistance, and has no cracking in outdoor application for a long time. It is generally believed that the insulation pad can be used outdoors for more than 20 years.
(4) High quality high temperature shrinkage * deformation.
(5) Excellent production and processing performance, easy molding and other advantages, according to the extrusion warm air vulcanized rubber molding, mold addition molding, extension molding and other ways to make a variety of products.
Because of its comprehensive performance and excellent safety engineering practical effect, insulating rubber sheet has been widely used in Airlines, aerospace, nuclear energy, household appliances, electronic devices, instrument panels, vehicles, mechanical equipment, metallurgical industry, chemical plants, medical services and daily life.
