S-FOAM 65 FLEX POLYURETHANE FOAM

S-FOAM 65 Flex Polyurethane Foam is a two-component, flexible polyurethane foam with integral skinning and variable density options. This system does not contain MOCA or toluene diisocyanate and is practically odorless. Skin thickness is controlled by material and mould temperature, and the loading of the mould. Pigments may be added to the “B” side. Common applications are prototypes, prosthetics, medical training devices, movie special effects props and more. This material is frequently moulded behind flexible polyurethanes.

S-FOAM 65 Flex Polyurethane Foam at a ratio of 75/100 pbw produces a firm, quick recovery foam. At 60/100 pbw, the result will be a slightly softer foam. This product is supplied at a 75:100 by weight ratio. For best results using self-skinning foams, we recommend you use rigid mould materials such as TC-1630, instead of a silicone mould. Density is based off of free-rise, unrestricted samples. Typical castings in a closed mould with back pressure will increase density and reduce expansion rate. This will often require up to 1.5 to 2.5 times more foam than theoretical calculated amount of foam for a given volume and mould shape/geometry. Also temperature of liquid foam, relative humidity, and mixing technique (hand stirred vs jiffy mix with a drill) will also affect expansion rate of foam.
