hothree HSR-3500 (thermal conductive insulator) is a pure boron nitride filled and has high thermal conductivity, ultra-high voltage resistance,low density and low dielectric properties. The material is ultra-thin, soft, tough flexible, tough, adhesive backed and self-adhesive, it can meet the thermal insulation needs of new energy vehicle batteries and electronic packaging applications.hothree HSR-3500 (Thermally conductive insulating sheet) can be die-cut into various shapes,easy to operate. The thermal conductivity can reach 3.5w/m-k and the standard hardness is 88 shore00.Thickness is 0.25~0.5mm and the standard specification is W200mm*L200mm/sheet.Produced by our own formula, we can customize the color, hardness and thickness according to the requirements.hothree HSR-3500 (thermal conductive silicone gasket) Applications• Automotive electronics• Motor controls• Power semiconductorshothree HSR-3500 (Thermal Conductivity Silicone Sheet) can replace BERGQUIST SP2000,Sil Pad 2000,SIL PAD TSP 3500LAIRD TGARD-K52,LAIRD TGARD 220,DENKA BFG30,BFG45,BGF20,BGF80,DENKA FSL-BS
