New Products: Solvay adds to Ryton line

Rubber & Plastics News Staff

BOLLATE, Italy—Solvay has launched its first batch of Ryton polyphenylene sulphide extrusion grades that complement its Ryton PPS injection molding materials for use together in demanding automotive cooling line assembly applications.

The new extrusion series is available globally in three grades—Ryton XE3500BL, Ryton XE4500BL and Ryton XE5500BL. Solvay said the stiffness of these grades varies to fulfill requirements of flexible tubes with different wall thicknesses and diameters or for post-extrusion thermoforming.

According to the firm, flexible coolant lines made using Solvay's new extrusion polymer technology exhibit high melt strength, chemical resistance and thermal stability with enhanced tensile elongation and impact strength.

Solvay said its injection molding grades include Ryton XE5430BL (30 percent glass filled) and Ryton R-4-270BL (40 percent glass filled). These materials have exhibited a proven fit in many existing connector and bracketry fittings to enable automotive OEMs to design fully harmonized and integrated coolant line assemblies for engines and transmissions.
