TC1500B Series Electrically Insulating Thermal Sheet

TC1500B is a heat cure, low thermal resistance tape. This double-layer low-modules silicone provides low contact resistance and superior adhesion designed to absorb assemble and application shock and vibrations. This unique blend of modulus and strength also reduces application stress due to CTE mismatch.
Features: High performance insulating tape
Applications: Used to bond independent packaged semiconductors and heat sinks
