Prop Foam 4 Flexible Foam - All kit Sizes

  • $37.00


Important! Prop Foam 4 has a new, improved formula for better skinning properties! This new formula has a variable ratio, meaning you can vary the part a to attain different densities and skins. The new formula has a white part B. The new mix ratio is 37A:100B by weight.

Prop Foam 4 is a 37A:100B mix (by weight) polyurethane self-skinning, low density flexible foam that has a free-rise density of 4 lb per cubic foot. Prop Foam 4 flexible foam is excellent for large body props, padding, and back-filling large, flexible props and parts.

Prop Foams work best when cast into warm TinSil or PlatSil silicone molds. Prop Foam 4 is "self skinning," but PT Flex Casting Rubbers such as PT Flex 20 are ideal for sloshing into molds to create skins for foam props.

Prop Foam cures white but can be pigmented with PolyColors. (See urethane additives)
