Reichhold (Research Triangle Park, N.C.) has introduced DION 31068-00, a new low-styrene, UV-stabilized, resilient terephthalic resin for pultrusion applications. The material is direct injection-capable and was developed as a performance match to UV-stabilized, resilient, isophthalic resin systems, but without the cost and supply issues related to the isophthalic acid shortages. Use of the material reportedly yields a lower total cost for pultruders by enabling them to increase line speeds. In addition, the resin’s styrene level (30 percent or less), is compliant under California Rules 50 and 1162. According to the company, potential applications include window lineals, ladder rails, tool handles, fan shrouds, structural shapes, utility pole cross-arms and lower-end marine sheet piling/seawalls. Currently, the resin is available only in the U.S., Canada and Mexico.
