Abstract: Porous infusible polymer (IP) parts are made by incorporating 0.2 to 10 volume percent organic fibers, preferably with short lengths, into the particulate IP, consolidating the mixture under pressure and optionally heating, and then “burning off” the fibers. After the fibers are burned off the resulting part has porosity in which the pores are elongated, usually retaining the shape of the organic fibers. When these parts are exposed to moisture (which they usually absorb) and then suddenly heated they tend not to blister from vaporization of the water. This makes them useful as parts for aircraft (jet) and other engines and other applications where sudden temperature increase may occur.

Abstract: Expanded products, more specifically, rigid or semi-flexible foams of low density from 1.5 to 12 lbs/ft3 or more, with closed cells can be manufactured. The products have a PVC backbone with branches with methacrylate crosslinked with isocyanate through a reaction activated by ultraviolet or microwave radiation. The use of polyfunctional monomers that are sensitive to irradiation yields a higher cross-link density, which improves the physical and mechanical properties such as hardness, resistance to abrasion, ductility, and resistance to friction. The selection of monomers and oligomers allows the manufacturer to determine of the final properties of the foam. The process yields foams with extreme hardness and better shear factors making the foam an ideal product for aerospace and windmill use. These physical properties emerge during the post-curing process, preferably by use of compounds based on methacrylates in dispersion with PVC and isocyanates.
