DSM expands EV thermal management portfolio with new PPS grade.

A  new PPS grade formulated to optimize the performance of electric vehicle (EV)  thermal management systems has been introduced by DSM Engineering Plastics, Troy, Mich.  Xytron G4080HR is a 40% glass-reinforced PPS engineered for heat-aging performance, hydrolysis resistance, dimensional stability, chemical resistance at elevated temperatures and intrinsic flame retardancy.

Because  Xytron G4080HR is specifically formulated for typical EV thermal management system lifecycles, it is said to maintain its strength at continuous operating temperatures exceeding 130 C/266 F for 6,000 to 10,000 hours. In a recent 3,000 hour 135 C/275 F water-glycol fluid test versus a comparable competitor grade, Xytron G4080HR delivered 114% higher tensile strength and 63% higher elongation at break. The unique combination of resistance to heat, moisture and chemicals reportedly make the Xytron family of materials a preferred solution for applications in many industries, including:

  • Automotive: powertrain parts, turbo systems, thermal management, automotive electronics and lighting
  • Electrical and Electronics: connectors, structural parts, e-motors, bobbins, switches and sensors
  • Industrial: water management, compressors, heat pumps, appliances, small engines, aerospace, oil and gas, pneumatics and hydraulics


  • LSR Part III-- Choosing a Mixing/Metering System

    Liquid silicone rubber (LSR ) is a two component reactive chemical with a viscous, paste-like consistency.

  • Commingled Plastic Waste: New Gold Mine for Automotive Processors

    Instead of going to landfills, previously unusable mixed waste like auto shredder residue is yielding a new trove of inexpensive engineering resins for car parts. Sortation technologies derived from the mining industry can pull out usable ABS, PC, acrylic, PP, TPO, and PPO alloys.

  • Radiation Crosslinking Boosts Nylon Properties

    Demand for more robust plastics is creating new opportunities for radiation-crosslinked nylons, including nylon 6 and 66, which can serve as cost-effective alternatives to higher-cost, high-heat thermoplastics. Crosslinked nylons have higher heat resistance than their standard counterparts, along with better physical properties and abrasion resistance. Adapted from a paper presented at SPE ANTEC 2012.
