Terephthalic resin for pultrusion


Reichhold (Research Triangle Park, N.C.) has introduced DION 31068-00, a new low-styrene, UV stabilized, resiliant terephthalic resin for pultrusion applications. The material 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. The material also was developed to yield a lower total cost for pultruders by allowing them to increase line speeds. In addition, DION 31-68-00 has a styrene level of 30% or less, is compliant under California Rules 50 and 1162 and is direct injection capable. Potential applications claimed by Reichhold include window lineals, ladder rails, tool handles, fan shrouds, structural shapes, utility pole cross-arms and lower end sheet piling/seawalls. This material is available only in the U.S., Canada and Mexico at this time.
