RJH-880 series are a peroxide cross-linking silicone rubber for the insulation of fire-resistant safety cables. When exposed to a flame, it can transform itself into an insulating and ceramic material. It can withstand thermal stress and mechanical impact, maintain circuit integrity in case of fire.
