Heat moldable gel and foam composition

摘要

The present invention is directed to a novel heat moldable gel and foam composition and the process for making the gel and foam composition. The gel and foam composition comprises gel infused into cells of a foam. The gel is a blend of gelling agents, such as thermoplastic polymers, resiliency components, such as styrene-butadiene or styrene-isoprene copolymer and softening agents, such as oils. The foam preferably has a hardness less than or equal to a hardness of the gel.

主权项

1. A heat moldable composition comprising:
a solid foam having a plurality of cells, said plurality of cells being at least partially hollow, said foam having a hardness greater than 16 on a Type “OO” scale durometer and less than 45 on a Type “A” scale durometer; a gelling agent for imparting rigidity to said composition, said gelling agent being a thermoplastic polymer; a resiliency component for imparting rubber-like resilient characteristics to said composition, said resiliency component being styrene-butadiene copolymer; a softening agent for controlling flowability of said composition, said softening agent being oil; said gelling agent, said resiliency component and said softening agent being mixed together to form a gel, said gel being arranged inside said plurality of cells of said foam to form the composition; said foam, said gelling agent, said resiliency component and said softening agent being chosen to be of a type, and to be of a quantity, to cause the composition to have a hardness greater than 16 on a Type “OO” scale durometer and less than 45 on a Type “A” scale durometer and to soften to a hardness of less than 2 on a Type “OO” scale durometer at a temperature of 50 degree C.
