The Akulon Diablo PA66 GF25 and Akulon Diablo PA66 GF20 grades both leverage exclusive DSM technology to maintain tensile strength despite rigorous heat-aging tests exceeding 200°C for 3,000 hours. The unique formulation allows the material to attain high initial strength and to retain that strength with prolonged exposure to heat.

This inherent strength allows for thinner-walled part design, which can reduce total system mass by up to 40 percent. The material has also been designed to offer robust heat aging performance at both extreme as well as more moderate temperatures. This helps to ensure that the product performs over a wide range of performance conditions in order to cover a broad array of application needs.

“With the addition of Akulon Diablo PA66, DSM is pleased to offer a complete portfolio of advanced material solutions for challenging automotive air management applications,” said Jud Gibson, vice president, Commercial Americas, DSM Engineering Plastics.

DSM’s complete portfolio of blow-moldable material solutions for air management now includes:

Stanyl Diablo PA46-GF25 – Extreme peak and continuous temperature performance capability that meets even stringent turbocharged diesel requirements.

Akulon Diablo PA66-GF25/GF20 – A heat stabilized offering that delivers best-in-class specific strength and property retention performance at both extreme as well as moderate temperature conditions

Akulon Diablo PA6-I-GF15 – Robust processability and performance/cost balance to meet the requirements of positive pressure cold charge and some hot charge air duct applications.

Arnitel HT TPC-ES – Delivers flexibility for rubber replacement.
