Abstract
A microcellular urethane composition, comprising a polyol component, an isocyanate component having an isocyanate index ratio of from about 65 to about 145; and up to about 50% by weight of a nano-scale filler dispersed throughout the composition. Methods for producing a reinforced microcellular urethane component are also provided.
Claims22
A reinforced microcellular urethane composition, comprising:
- a polyol component;
- an isocyanate component having an isocyanate index ratio of from about 65 to about 145;
- and
- up to about 50% by weight of a nano-scale filler dispersed throughout the composition.
1 more element
A method for producing a reinforced microcellular urethane component, the method comprising:
- dispersing a nano-scale filler with a polyol component to form a polyol mixture;
- metering the polyol mixture with an isocyanate component in an amount having an isocyanate index ratio of from about 65 and about 145;
- blending the resulting mixture;
- depositing the mixture into a tooling device and forming a reinforced microcellular urethane component.
1 more element
A method for producing a reinforced microcellular urethane component, the method comprising:
- dispersing a nano-scale filler with a polymer mixture, the polymer mixture comprising a polyol component including a blend of polyether polyol and polyester polyol, and an isocyanate component present in an amount having an isocyanate index ratio of from about 65 to about 145;
- blending the resulting mixture;
- depositing the mixture into a tooling device and forming a reinforced microcellular urethane component.
