Arnite® A: The perfect PET

Arnite A is high-performance polyethylene terephthalate (PET) with an increasingly wide range of applications – from automotive to lighting. Thanks to its excellent mechanical performance, heat resistance and dimensional stability, Arnite A is perfect for metal replacement offering significant weight, carbon – and cost – reductions.

Our Arnite A PET outperforms PBT in both mechanical and heat performance while also offering better dimensional stability. Its toughness makes Arnite the ideal choice for demanding automotive applications like brake booster valve bodies, mirror brackets and lighting frames - where consistent performance over time is essential.

In automotive lighting, we offer special grades of Arnite for low outgassing applications (Arnite XL) as well as grades with extreme dimensional stability and accuracy.

Beyond automotive, Arnite A is increasingly used in electrical applications like low-voltage switchgears, bobbins, and lamp holders. Meanwhile, we offer special extrusion grades for stock shape applications, offering superb processing characteristics and excellent tribological properties; ideal for applications like gears and bushings.


Arnite A is a plastic. Despite being strong like metal, it doesn’t rust or break like metal. The material has a wide range of processing characteristics: It’s easy to mold, has good wear resistance, and very good color stability.

It’s also the more sustainable choice. In automotive applications, where weight reduction equals lower fuel consumption and carbon emissions, Arnite is helping manufacturers hit sustainability targets and avoid fines that can increasingly reach of millions of Euros.

Typical grades:

  • Arnite A06 101 - Unfilled PET mainly for stock shapes
  • Arnite AV2 370 /B - Glass-reinforced PET ideal for brake booster parts

Arnite® T: The ideal PBT

Arnite polybutylene terephthalate (PBT) is an extremely versatile high-performance thermoplastic with a wide range of grades. It’s also halogen-free, which provides a major boost for manufacturers looking for a sustainable solution.

Our Arnite T thermoplastic is incredibly versatile, based on the unique needs of our customers. It’s available in a range of grades including unfilled, glass filled, flame retardant, impact modified and many more. We even offer tailored PBT/PET blends.

The material is resistant to solvents, shrinks very little during forming, is mechanically strong with good dimensional stability, and is heat-resistant up to 150 °C (or 200 °C with glass fiber reinforcement). Arnite T also offers good processing characteristics. It’s easy to mold, has good wear resistance and very good color stability.


What really makes Arnite T stand out is the increasingly creative applications that manufacturers are finding for it. In white goods connectors, the material is halogen-free, based on a flame-retardant system that contains no halogen or red phosphorus. In consumer applications - like perfume bottles - the material is proving popular because it looks and feels like an expensive ceramic.

As for what the future holds, we envisage more consumer-led applications as Arnite T replaces metal (and indeed some plastics like polyamide 66) by providing a lighter, stronger, greener – and less expensive solution

Typical grades
