Fiberglass thermal pad

FSK series fiberglass thermal pad is a super soft single side silicon tape enhanced thermal conductive pad. The product has excellent mechanical properties and insulation performance; ultra-low hardness, good resilience and high compression ratio, is applicable to large institutional design of tolerance. Because of its low hardness, it has smaller thermal resistance in the case of low pressure, eliminate the air between the components and circuit boards, and full fill all kinds of rough surface at the same time. By special ultra-thin glass fiber cloth double-layer structure, increase the operability and durability, it will not be broken and deformation when stamping, punching or deformity design.

Product Description

FSK12 has the same highly conformable, low-modulus polymer as the standard Gap Pad 1500.The fiberglass reinforcement allows for easy material handling and enhances puncture, shear and tear resistance. The natural tack on both sides of the material allows for good compliance to mating surfaces of components, further reducing thermal resistance.


• Super soft, high-pressure shrank, high deformation 

• Fiberglass reinforced for puncture, shear and tear resistance

• Easy release construction

• Electrically isolating
