Thermal gap pad
China [CN] 
This series of products are resilient and with large deformation, suitable for large institutional design tolerances. Single or Double layer structure, The Double layer is reinforced with special ultra-thin fabric to increase resistance and workability of punching, strip type, Malformation designs. Self-adhesive and never recede. No corrosion to the Copper surface, “enviromentally friendly products”.|
