Double-sided adhesive film with long-lasting adhesion

KERATHERM® Adhesive Films are double-sided, thermally conductive, electrically isolating adhesive films.

Ceramic filled double-sided adhesive film – with or without fiber glass fabric KL 90 and KL 91 – are double-sided adhesive films. They have excellent, permanent adhesive strength with very high thermal conductivity and outstanding insulation properties. Low heat transfer resistance can be achieved by very reliable adhesive strength on different surfaces. There is no need for mechanical fastening with clips, screws or rivets. Tolerances can be compensated very effectively thanks to the soft surface finish. Other advantages include light weight, easy handling and high elasticity.
