Combining Excellent Flow with Good Mechanical Strength

Envalior's (formerly DSM Engineering Materials) Arnite® portfolio includes high-performance polyester compounds (PET, PBT and blends) that combine high strength and rigidity with excellent processing characteristics, ideal for a broad range of automotive and E/E applications. Production locations are available in Europe, the US, India, and China.

Why Arnite®

Why Arnite®

Arnite® (PBT, PET, and blends) is a high-performance engineering plastic that combines high strength and rigidity with excellent processing characteristics. As a result, Arnite® A (PET) and Arnite® T (PBT) are well suited for a broad range of automotive, electrical and electronics, and consumer goods applications. A wide portfolio of Arnite® is available, including unreinforced, reinforced, and flame-retardant grades.


Characteristics and Properties

Arnite®'s characteristics and properties include:

  • Excellent dimensional stability
  • High strength and stiffness at ambient conditions
  • Hydrolysis resistant

Markets and Applications

Automotive and Mobility

Automotive and Mobility

Arnite offers good dimensional stability and ESD performance and allows for lightweight solutions, in comparison to metal. Arnite® PBT is ideal for automotive connectors due to its high temperature resistance, high mechanical property levels, and good electrical insulation properties. Typical applications include:

  • Actuator covers
  • Automotive lighting systems (headlights, LEDs, foglamps, bezels and AFL frames)
  • E-Boxes
  • Wire-to-wire connectors
  • Wire-to-board connectors
  • High-voltage connectors
  • High-temperature connectors
  • PBT connectors
  • Radar sensor housings
  • Reflow connectors
  • Vacuum brake boosters
  • Rearview mirrors

Consumer Goods

Consumer Goods

LEDs are setting designers free to create concepts that consume less energy than conventional light sources. Arnite® is a material solution for reflective LED applications that can handle both high-temperature applications and long-term resistance to heat and radiation. Typical applications include:

  • Reading lamps
  • TV screens
  • Street lighting


Envalior’s Arnite® PBT provides a proven solution for precision inhaler valve components due to its dimensional stability, easy processing, low extractables, and low moisture absorption. This helps maintain performance to control dose accuracy.
