THE WOODLANDS, TEXAS (July 22, 2009) - With low halogen content standards becoming commonplace in the electronics industry, Chevron Phillips Chemical Company LP's (Chevron Phillips Chemical) Engineering Polymers group is introducing several new Ryton® polyphenylene sulfide (PPS) resin grades with chlorine content of less than 900 parts per million.
Ryton® PPS R-4-280 is a 40 percent glass-filled PPS, offering electronics and electrical component manufacturers a strong resin well suited for connectors, bobbins and other hard disc drive (HDD) structural applications. Ryton® PPS R-7-190 is a glass and mineral-filled PPS for applications where dimensional stability, stiffness, and electrical properties are required.
"Our new grades are designed with the electrical, electronics, and computer industry in mind," said Bob Goodman, product manager for Chevron Phillips Chemical's Engineering Polymers group. "We are using the latest technology to produce these resins and are achieving the reduction in chlorine content without sacrificing any of the resin properties, such as excellent flow, that our customers depend on from Ryton® PPS."
Using new polymerization process technology, Chevron Phillips Chemical is able to achieve the desired targets in chlorine content. This process technology allows PPS polymer to be produced in a wide variety of molecular weights, which provides the capability to produce a range of molding compounds from which to choose.
Ryton® PPS offers superb value for electrical and electronic applications. With excellent flow and low shrinkage for precision molding of connectors and sockets, and superior stiffness and mechanical integrity for reliable assembly, Ryton® PPS is one of the most stable material choices for electrical applications. Additionally, all Ryton® PPS compounds have UL94 V-0 flammability ratings without the use of flame retardant additives.
