Resonators: Making the complex simpler
Resonators are complex applications that reduce the noise in the engine air system. They need to perform reliably at high temperatures and pressures. That’s why we developed a family of thermoplastics that cover the full operating temperature range while achieving weight reduction and lower system costs.
We offer a wide range of thermoplastics for resonators that can operate at peak temperatures of up to 280°C. Our Akulon® Diablo and Stanyl® Diablo grades in particular provide long-term heat resistance of up to 3000h at 230°C.
One of the most significant advantages of the Diablo family is its weldability, weld line strength and ability to maintain strength (mechanical performance) after aging of the weld line. All this while delivering significant weight reduction – and therefore cost reduction.
Metal replacement and plastic comparison
Our materials offer benefits over both metal and other plastics.
For metal replacement, Stanyl and Stanyl Diablo are 40% lighter– which equates to lower fuel consumption and reduced CO2 emissions (important for the industry as regulations tighten around the world). Furthermore, it can help you achieve reduced systems costs of up to 20% through improved processing and function integration.
When it comes to PPS replacement, we can help you achieve weight reduction of 10% through the design of components that, thanks to Stanyl, have thinner walls. This is due to Stanyl’s superior weight-to-strength ratio as well as its increased toughness, better processing and weldability.
Versus PA and PPA Stanyl and Stanyl Diablo can cope with temperature and time requirements while all other aliphatic and partially aromatic polyamides completely disintegrate at sustained exposure to temperatures above 200°C.
On the other hand if you need a material for long-term heat stability up 200°C you might want to consider the newest addition to the family: Akulon Diablo polyamide 6.
