Reaction to fire of rigid polyurethane foam

Polyurethane rigid insulation reaches a classification from B to E in reaction to fire, depending on a number of factors such as formulation and type of facings. Additional classifications are used as an indication of the smoke production for building materials: s1, s2 and s3 where in the case of s3 there is no restriction on the smoke production.

Fatigue studies of polyurethane sandwich structures

The lowest fatigue properties have been obtained for the polyester/glass-PUF-polyester/glass sandwich panel specimens. Better performance of the epoxy/glass-PUF-epoxy/glass sandwich panels is most likely due to the superior properties of the outer thin skins. Most of the specimens fail within the foam region and not at the skin level.

Open vs. Closed Cell Foam: Understanding Permeability

Aug 24, 2018 · Created using a similar process as closed cell foam, open cell foam is designated to be vapor semi-permeable as the formation of the cells in the material are broken, rather than closed. Similar to the holes inside a sponge, air can permeate the open cells more easily, making open cell foam more porous and absorbent than closed cell foam.
