interface and electrical insulator between

electronic components and heat sinks.

In the thickness range of 10 to 40 mil,

tack on both sides, allowing for excellent

compliance to the adjacent surfaces of

components.The 40 mil material

thickness is supplied with lower tack on

one side, allowing for burn-in processes

and easy rework.
