Ticona Engineering Polymers (Florence, Ky. and Kelsterbach, Germany) has added a new material to its family of inherently flame-resistant liquid crystal polymers (LCP). Vectra T. rex LCP is designed for thermal forming processes and offers high dimensional stability, good high-temperature performance and chemical resistance. The material’s high melt viscosity and melt strength make it well suited for extrusion and thermoforming. Initially, the company is offering a 40 percent mineral-filled grade, Vectra T. rex 541, which provides impact and notched-impact strengths that, the company reports, are significantly higher than those of other mineral-filled grades. Other benefits include a heat deflection temperature (HDT) of 245°C/473°F, 20 percent improvement in impact performance vs. standard 40 percent mineral-filled LCP and melt viscosity up to three times greater than standard 40 percent mineral-filled LCP. Target applications include medical trays and equipment, aircraft interiors (good flame/smoke/toxicity data has been reported) and semiconductor chip carriers.
