image of SOMATAC CR

SOMATAC CR Series are films used in production processes, which have weak adhesion at normal temperature, and gain adhesion by heating.
Various types of products with different adhesion-gaining temperatures and peeling strength are available.


  1. Develops adhesion when heated.
  2. At normal temperatures, peeling strength declines largely as compared with when heated.
  3. As the peeling strength is very weak, it can reduce peeling stress to the objects to be adhered.
  4. Particularly suitable for use as a support material for extremely thin films.
