Akulon® Diablo

Akulon Ultraflow is a high-flow grade proven to help manufacturers reduce injection molding cycle times by up to 40%.

Explore Akulon® Diablo

Akulon Diablo is our high heat resistant polyamide 6/66, ideal for metal replacement in under-the-hood applications up to 220°C. We created Akulon Diablo as a material to help customers tackle the ever-challenging temperature range within smaller, hotter turbo engines. As a result, the latest grade – Akulon Diablo HDT2500 – delivers a 3,000 hour continuous use temperature of up to 220°C with a significant improved HDT value.

Akulon Diablo is ideal for metal-to-plastic replacement in components for air intake systems, ranging from charge-air-cooler endcaps and air intake manifolds to air intake ducts, turbo exhaust resonators and engine covers. With its reduced weight, this material reduces both fuel consumption and resultant carbon emissions – good for people, planet and profit.


Featured applications

Hot Charged Air Ducts

Automotive | Engine Air Intake

Stanyl® PA46, Stanyl® Diablo PA46, Akulon® Diablo PA and Arnitel® HT TPC allow for light weight solutions as compared to metal or rubber or alternative plastics (Stanyl® is 10% lighter than PPS); Stanyl® PA46, Stanyl® Diablo PA46, Akulon® Diablo PA and Arnitel® HT TPC allow for cost effective solutions (Stanyl lowers system cost up to 20% versus metal); Stanyl® PA46, Stanyl® Diablo PA46, Akulon® Diablo PA and Arnitel® HT TPC allow for reliable solutions (Stanyl® Diablo is long term resistant up to 230 ˚C, Akulon® Diablo ca be used around 200 ˚C) and Arnitel® HT is ideal as single part solution for flexible hot charge ducts.

Integrated Air Inlet Manifolds (up to 230°C)

Automotive | Engine Air Intake

Stanyl® Diablo and Akulon® Diablo allows for 40% lighter and 20% lower system costs in comparison with metal; Stanyl® Diablo allows for reliable solutions due to its long term heat resistance up to 230°C (in absolute strength values better than PPS) and due to its great welding strength (even better than PA6); Akulon® Diablo positioned to be positioned upto 220 ˚C

Charge Air Cooler Caps

Automotive | Engine Cooling / Thermal management

Stanyl® PA46 allows for light weight solutions (40-50% lighter) and more cost effective solutions than metal; Stanyl® PA46 allows for reliable solutions due to its better creep/fatigue resistance than PPS and PPA and in case of Stanyl® Diablo due to its excellent long term temperature resistance up to 230°C; Akulon® and EcoPaXX® allow for light weight solutions (40-50% lighter) and more cost effective solutions than metal at the cold side.; Xytron™ PPS allows for super high temperatrue resistance for long term.

Setting a new standard in high temperature components

As engine designers are challenged to create smaller, lighter, more powerful systems, DSM is innovating the materials to make it possible. DSM’s Diablo heat resistant technology is making Stanyl PA46 and Akulon PA66 the choice of the world’s leading car brands, by setting the new standard for high temperature components. Let’s talk about creating tomorrow’s engines today.

Chemical and gas resistant automotive plastic

Akulon Diablo can be blow molded or injection molded and is easy to process. In fact at DSM we’re more than a materials provider: We offer extensive application knowledge to support customers with CAE, design and design optimization, so they can meet OEM requirements.

Akulon Diablo has outstanding resistance to chemicals and gases in EGR (exhaust gas recirculation) systems; plus excellent processing properties that create finished parts with high burst pressure weldline strength for injection molded parts and a high quality surface finish.
