• Polyester resin fiberglass systems: sheet molding compounds and bulk molding compounds; filament winding; wet lay-up lamination; repair compounds and protective coatings. • Polyurethanes: insulating foams, mattresses, coatings, adhesives, car parts, print rollers, shoe soles, flooring, synthetic fibers, etc. Polyurethane polymers are formed by combining two bi- or higher functional monomers/oligomers. WebbHigh temperature thermoplastics (as all polymers) comprise two molecular structures: amorphous (randomly ordered) and crystalline (highly ordered). For practical purposes, thermoplastics are either amorphous polymers or semi-crystalline polymers which have both amorphous and crystalline regions.

Webb22 juli 2024 · Thermoplastics, which make up about 75 percent of worldwide plastic production, can be recycled by heating them again until they become liquid, so they can be remolded into a new shape. Thermoset plastics are made by a similar process, but once they are cooled from a liquid into a solid, it is very difficult to return them to a liquid state.
