THE WOODLANDS, TEXAS (June 23, 2006) – Chevron Phillips Chemical Company LP (Chevron Phillips Chemical) has announced a name change for the “Ryton” organization. The new name is “Engineering Polymers,” which reflects the group’s growing portfolio. The name change will encompass the well-known products sold under the Ryton^® polyphenylene sulfide (PPS) and Xtel^® PPS alloys brands.

“With a thirty-plus year history, the Ryton organization has always been the worldwide leader in the PPS market,” said Mike McDonnell, Chevron Phillips Chemical’s Engineering Polymers General Manager.  “We continue to be at the forefront of developing new high-performance engineering resins and alloys. The new Engineering Polymer name more clearly demonstrates our commitment to future growth and development.”

A lightweight alternative to metal, Ryton^® PPS can easily be molded or extruded. Its minimal moisture absorption and low coefficient of linear thermal expansion makes Ryton^® PPS an excellent option when molding complex parts in tight tolerances. Additionally, Ryton^® PPS provides ease of processibility that enables manufacturers to integrate multiple components into one, reducing time and costs. This versatility makes Ryton^® PPS a preferred choice in automotive, electronic, industrial and appliance industries worldwide.

In 2003, Chevron Phillips Chemical introduced Xtel^® PPS alloys. These alloys offer similar resistance and stability as Ryton^® PPS with the added benefit of elasticity. In addition to its flexible traits, Xtel^® PPS' excellent flow in thin walls translates to low flash characteristics and fast cycle times.

The combination of Xtel^® PPS and Ryton^® PPS product offerings provide customers with a broad range of PPS technology. Both Ryton^® PPS and Xtel^® PPS products are backed by Chevron Phillips Chemical’s renowned technical and customer service. To find out more, visit http://www.cpchem.com/.
