Chevron Phillips Chemical Debuts New Low-Chlorine PPS

28 Nov 2008 • by Natalie Aster

In anticipation of low halogen content standards for the electronics industry, Chevron Phillips Chemical Company LP's (Chevron Phillips Chemical) Engineering Polymers group has introduced two new Ryton® polyphenylene sulfide (PPS) resin grades with chlorine content of less than 900 parts per million.

Ryton® R-4-280 is a 40 percent glass-filled PPS, offering electronics and electrical component manufacturers a strong resin well suited for connectors and other hard disc drive (HDD) structural applications. Ryton® R-7-140 is a 65 percent glass and mineral-filled PPS for applications where dimensional stability and electrical properties are very important.

"Our new grades, R-4-280 and R-7-140 are designed with the electrical, electronics, and semiconductor industry in mind," said Jay Blackburn, Business Development 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 without sacrificing any of the resin properties that our customers depend on from Ryton® PPS."

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.

These Ryton® PPS grades will be made widely available with the completion of Chevron Phillips Chemical's new plant in Borger, Texas, scheduled for early 2009. Customers, however, may receive prototype material at this time upon request.
