• 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.
Thermosetting polymer - Wikipedia
Polylactic acid (polylactide) is a compostable thermoplastic aliphatic polyester derived from renewable resources, such as corn starch (in the United States), sugar beet pulp (in Europe), tapioca roots, chips or starch (mostly in Asia), or sugarcane. It is the most common material used for 3D printing with fused … Visa mer A thermoplastic, or thermosoft plastic, is any plastic polymer material that becomes pliable or moldable at a certain elevated temperature and solidifies upon cooling. Most thermoplastics have a high molecular weight. … Visa mer Today’s acrylics industry can be divided into two distinct multibillion-dollar markets: on one hand the polyacrylic acids (PAA) and its ester … Visa mer Nylon belongs to a class of polymers called polyamides.
