This foam is an elastomeric polyurethane that when fully cured forms a tough abrasion resistant rubber foam part. Available now, this product is made with these resins have an integral rubber skin with an excellent cosmetic finish.
FX 300 is formulated to be hand mixed and poured into closed molds. Foams which are classified as "self skinning" or "integral skin foams" form a rubber like outer skin surface as they expand against the walls of a closed mold cavity. The most common use for self skinning foam is in the manufacture of dash panels of automobiles or to cast soft characters for playground themeing. For automotive dash panel applications heavier 8 to 12 pound density foams are more frequently used. Our flexible expanding foam has good impact resistance and durability; we offer a selection of 12 color options (see color pigments and dyes product page on our web site). We recommend using darker colors for applications which are exposed to direct sunlight. Our open cell flexible foams are not recommended for flotation applications as they will absorb water with long term submersion. See our rigid expanding foams product page for closed cell flotation foam. A mold release agent or wax must be used to prevent foams from sticking inside mold cavity, see video demonstration on for more information.
