Patent

CA 2305246

The invention relates to microcellular rigid foams with a matrix consisting of cross-linked duromers, especially of polytriazine resins, and with an apparent density of 20 to 95 % of the density of the compact matrix material. The inventive rigid foams are highly stable and highly temperature-resistant and are suitable for use e.g., as material for aircraft lining.

L'invention concerne des mousses dures microcellulaires ayant une matrice en duromères réticulés, notamment en résines polytriazine et dont la masse volumique apparente correspond à 20 à 95 % de la masse volumique du matériau matriciel compact. Ces mousses dures présentent une résistance et une constance thermique élevées et s'utilisent par exemple comme matériaux de revêtement pour avions.
