Hytrel® 8238HS NCB010

Supplied byCelanese- Last Updated on May 12, 2026

Hytrel® 8238HS NCB010 by Celanese is a plasticizer-free thermoplastic polyester elastomer grade. It is a light- & heat stabilized grade and contains a non-discoloring- and cube blended stabilizer. Exhibits high modulus, nominal hardness, excellent toughness and resilience.
  • Also exhibits flexibility at low temperatures and good retention of properties at elevated temperatures.
  • It offers good melt stability and enables the recycling of properly handled production waste.
  • Provides high resistance to creep, impact, flex fatigue, industrial chemicals, oils and solvents.
  • It has low fuel permeability and is suitable for processing by injection molding, thermoforming, casting, film and sheet- & other extrusion.
  • Hytrel® 8238HS NCB010 is used in cubing, gears, sprockets, electrical connectors, oil field parts, wire and cable applications.
  • It is also used in automotive, fluid power, consumer goods, appliance and power tool, sporting goods, furniture, industrial and off-road transportation/equipment industry.
