When two-portion PUs are used, pultruders can dispense with some of the more costly reinforcements, such as fabrics, that otherwise are requisite to ensure that the part achieves the desired strength. PU resins principally provide higher mechanical properties than the standard thermosetting resins typically habituated to in pultrusion, including better shear, transverse tensile and weight values. The part wall thickness also can be reduced, with a corresponding reduction of into a receive cost. Although an injection die, rather than a resin bath, is a requirement and, therefore, hardware costs are higher, Martin contends that the payback is a party that performs better and opens up huge markets for pultruders, including shelving and ladder... s employment in the area of pultruding with two-part polyurethane (PU) resin, in disparity to traditional thermosets.
