High performance thermoplastic resins and their composites. (wikipedia.org)
Both thermosetting resins and thermoplastic resins may serve as matrix resin, but thermosetting resins are in wider use because they serve easily to impregnate reinforcing fiber. (justia.com)
When heated, a thermoset resin does not melt like a "thermoplastic" resin, but it can significantly reduce in strength near the glass transition temperature range (Tg). (napipelines.com)
Even at typical plastics-processing temperatures, other thermoplastic resins are too high in viscosity to flow among and moisten the fibers used in creating a composite, which typically is 70% glass (or other) fibers. (industryweek.com)
The Dow Isoplast thermoplastic urethane resins used in the Fulcrum technology, however, actually "depolymerize at processing temperatures, dropping to a viscosity below the melt viscosity of any existing thermoplastic polymer, allowing flow and wet-out of the fibers to occur," says Chris Edwards, market development engineer and project leader.
