At K 2019, Ascend Performance Materials launched new specialty polyamides Vydyne® XHT, long-chain polyamides (LCPA) and high-temperature polyamides (HTPA) for automotive applications.

Vydyne XHT, is a heat-stabilized polyamide 66 and copolymers which is capable of withstanding prolonged exposure to temperatures up to 230°C. It uses combination of unique polymer chemistries and a multi-stage heat stabilization technology.

XHT products push the boundaries of temperature resistance without sacrificing the processability, durability and mechanical properties.

“Consistent high heat performance is critical in under-the-hood applications to accommodate for various load, torque and speed conditions in engines, said Vikram Gopal, Ascend’s Senior Vice President of Technology.

Applications of Vydyne XHT


The Vydyne XHT portfolio includes four glass-filled grades ideal for use in demanding automotive applications, such as charge air coolers, integrated air intake manifolds, exhaust gas recirculators and resonators.

All XHT grades exhibit excellent flow, are regrindable, allows excess material to be reprocessed which improves production efficiency.

PA610 and PA612 Long-chain Polyamides


Ascend also introduced a new portfolio of PA610 and PA612 long-chain polyamides. Ascend’s LCPA have low moisture absorption, high chemical and UV resistance.


The LCPAs are engineered for a variety of applications, including

  • monofilaments,
  • battery seals,
  • cable ties,
  • automotive cooling,
  • fuel connectors,
  • sporting goods.

“Our customers are driving innovation and meeting increasing demands across the industries they serve, In turn, we are building off our vertical integration and strong position in PA66 to bring the greater reliability, functionality and flexibility to make that innovation possible.” said Phil McDivitt, Ascend’s President and CEO.

The company is also expanding into high-temperature polyamides. Ascend’s new HTPA grades offer higher strength, stiffness, chemical- and temperature-resistance for metal replacement and high-heat automotive applications.
