Chevron Phillips Chemical has introduced a new polyphenylene sulfide (PPS) for applications needing an extra measure of mechanical strength, toughness and weld line integrity. Ryton® R-4-260 PPS, a 40 percent glass-filled grade, exhibits 50 percent less micro-flash than current high-elongation PPS compounds. It has a tensile strength above 25,000 psi and a flexural strength of 34,000 psi. Applications include desktop and laptop hard disk drive connectors, and other electronic hard drive connectors used in the consumer electronics digital video recorder (DVR) and gaming markets.
