Abstract
A standard polyurethane doped with a polymeric gel uniformly diffused in the body, where the polyurethane acquires the properties of the gel without any change to its structure in a durable stable manner.
Claims15
A composite material for making an article with polyurethane foam comprising a silicone gel evenly distributed throughout the material in a concentration of between 2% and 50% of the total mass of the article.
(canceled)
A procedure for making an article out of polyurethane foam comprising the steps:
- preparing a polyoil-based component and a silicone gel;
- reducing the silicone gel to granules with dimensions ranging from less than a millimeter to 5 millimeters;
- mixing said silicone gel granules in said polyoil base to form a mixture;
- combining said mixture with an isocyanate component in order to obtain a polyurethane foam mixture.
- delivering the polyurethane foam mixture on a foaming line;
- polymerizing said polyurethane foam mixture until a product obtained from the polymerization of said polyurethane foam mixture can no longer become deformed under its own weight;
- and
- cutting the blocks obtained from the foaming line.
