Polymers and Associated Materials Cellular polymer resulting from the reaction between an isocyanate component and a polyol component.

Mixture of two resins that create a chemical foaming reaction. Polyurethane foam. Once cast and removed from the mould it is difficult to differentiate from wood or plaster components. Characteristics of the finished product include resistance to rotting, splitting, warping, paint peeling, chipping, and insects.

a foam made by adding water to polyurethane plastics

This family of foams differs from other cellular plastics in that foaming occurs simultaneously with polymer-forming reaction between a diisocyanate and a polyol.

See Urethane Foam.

Man-made spongy material used as the padding of choice over the wooden frames of upholstered seat furniture.

A type of synthetic, flexible foam.

Less rigid than polyethylene foam. Used in case interiors.

A synthetic material used for cushions in upholstered furniture such as sofas and chairs; better upholstered furniture uses high-density polyurethane foam.
