Abstract:
Integrally bonded composite polyurethane foams substantially free from coalescence and with no discernable bond or interface layer when viewed at 50X magnification can be formed by wet casting a second foamed polyurethane composition onto a first wet cast foamed polyurethane composition and simultaneously curing the cast foams. In a preferred embodiment, one curable polyurethane composition forms a slow recovery foam and the other curable polyurethane composition forms a resilient foam.
Abstract:
A silicone grip comprising a cured silicone film layer with a Shore A Durometer of less than or equal to about 60 wherein the silicone film layer is formed from a curable silicone composition comprising a catalyst that promotes cure of the silicone composition, a higher molecular weight organopolysiloxane having at least two alkenyl groups per molecule, a lower molecular weight organopolysiloxane having at least two alkenyl groups per molecule, and an organopolysiloxane having at least two silicon-bonded hydrogen atoms per molecule. The cured silicone layer is used in combination with an adhesive to provide a flexible and malleable grip, and/or in combination with a backing layer that can be solid or foamed.
