ABSTRACT:
A novel, flexible composition is disclosed which contains reinforcement encased in intimate contact with a melt blended mixture of low durometer polymer gel. The reinforced polymer has unique properties obtained from the combination of reinforcement and elastomeric gel. Density, thermal conductivity, flexibility, elongation and strength are some of the properties which may be tailored by modifying the reinforcement and polymers. The combination of reinforcement with thermoplastic and oil create a gel and allows for deformation and impact resistance not obtainable with standard elastomers including vinyl, rubber or silicon. The addition of reinforcement makes it possible to tailor the gels properties while still maintaining many of its unique attributes. Particulate reinforced parts can be formed into a desired shape and take on some of the properties of the reinforcement. They can be deformed during use, but because these elastomeric gels have a high elastic memory, they return to their original shape. In addition, fiber reinforcement can be used to block deformation in specific directions. These and other properties make this system ideal for many applications including weights, shock absorbers, medical devices, seals, etc.
