Abstract
Filamentous bodies which are longitudinally extended and other film-like constructions are made by combining liquid silicone-containing precursors with air and extruding them. Distinct types or grades of fibers, strands, and other film-like constructions are produced which have a multiplicity of useful applications and indications for use owing to their inherent memory, compactability, tensile strength and density. Processes for making the novel enhanced filamentous bodies and products by the same can be optimized for uses ranging from safe and effective (“leak-free”) prosthetics to cushions, inserts, membranes, in a plurality of fields from consumer electronics to medical devices, and athletic or orthopedic shoe inserts.
Claims5
A composition comprising aerated silicone filaments, said aerated silicone filaments comprising a compound having a first silicone rubber (A) and a second silicone rubber (B), the first silicone rubber comprising dimethyl methylvinyl siloxane and the second silicone rubber comprising dimethyl methylhydrogen siloxane,
- wherein the aerated silicone filaments have elastic memory, and tensile strength, wherein the composition is generated by a process for generating novel silicone constructions, comprising, in combination, the steps of:
- providing predetermined aliquots of two different liquid silicone rubbers A and B;
- combining at least one ratio selected from the group consisting of 30/70, 40/60 and substantially equal measurements of the respective aliquots of the two different liquid silicone rubbers;
- adding air to the combinant silicone mixture;
- mixing the resulting silicone emulsion to create a fluffed emulsion;
- and finishing the process to create a desired end product, and wherein the finishing step further comprises:
- pressing the fluffed emulsion through a pressing machine equipped with at least one of a wire mesh screen assembly and a die plate;
- extruding silicone filaments onto a receiving plate;
- and, drying the silicone filaments inside of a heating chamber.
