Explore Xytron™ PPS Plastic

Xytron™ PPS plastic offers extreme chemical resistance, dimensional stability, and is intrinsically flame retardant. It also offers high stiffness up to a glass transition temperature of 90°C, with a continuous use temperature (CUT) between 240-260°C. Xytron™ is well suited for a broad range of Automotive, E&E and Specialized Industrial applications.

Xytron™ PPS Material Portfolio Highlights:

• Hydrolysis resistance: PPS materials fit best for applications that are exposed to higher heat and need to maintain dimensional stability while being subjected to harsh chemicals.

• Food contact and drinking water: PPS plastic has global drinking water approvals, including NSF, KTW, WRAS and ACS; it also complies with FDA requirements for food contact applications. Ideal for use in higher pressure, hot water applications, PPS materials can be used at temperatures up to 95°C.

• High impact: This class of materials enables applications that require high impact resistance or experience frequent temperature changes. These grades are engineered to solve brittleness problems common with standard PPS grades.

Hydrolysis Resistant PPS Material
PPS plastics fit best for applications that are exposed to higher heat and need to maintain dimensional stability while being subjected to harsh chemicals. Typical applications include coolant pump impellers, upper and lower portions of the radiator, and exhaust gas pumping systems.

It is known that PPS plastic and glass are both good at hydrolysis resistance. But the interface of glass and PPS material is the weak point for a glass reinforced PPS compound during the hydrolysis process. Thanks to good bonding technology, DSM G4080HR outperforms competitors’ materials. The retention strength is still around 80% of its initial value after 3,000 hours of aging at 135°C.
