德國(guó) Kerafol Keratherm KL 90 and KL 91

Ceramic filled double-sided adhesive film -with or without fiber glass!

are double sided adhesive films. They have an excellent, permanent adhesive strength with high thermal conductivity as well as very good insulation properties at the same time. Low heattransfer resistance can be achieved by a very reliable adhesive strength on different surfaces.

Mechanical fixation with clips, screws or rivets are not necessary.
Due to the soft surface finish, tolerances can be compensated very well. Light weight, easy handling as well as high elasticity are further advantages.
