To offer a drop-in solution to overcome the PA66 shortage, we developed an alternative material: The Akulon® IG series is a portfolio of material grades made by combining the strength of PA6 and PA46 – two materials that are fully independent of the Adiponitrile/hexamethyldiamine supply.
Automakers look to new solutions to meet Bharat Stage VI emission requirements
Legislation in India is placing tighter limits on emissions from automobiles. In 2020, automakers will need to meet strict emission standards that are equivalent to standards in the United States, Japan and the European Union. Consumers in the market for a new car will soon be driving vehicles with advanced technologies that meet these emission requirements.
According to a World Health Organization report released in 2016, India is home to half of the 20 most polluted cities in the world. The catalyst for the emission standards is to decrease air pollution; thus, improving the environment and people’s health.
In 2020, the country is moving from Bharat Stage IV (BSIV) to Bharat Stage VI (BSVI). Bharat Stages are auto emission norms based on the European emission standards adopted in 2000. Bharat Stages place a limit on pollutants released, which is controlled by modifications made in vehicle systems to control pollutants.
Global automakers and Indian automotive companies have been working on solutions to meet the emission requirements. According to the article, “How India’s auto industry is racing to meet 2020 Bharat Stage VI deadline,” Indian companies need to develop solutions from the ground up with help from global technology firms while regional divisions of global automotive companies will work with parent companies.
Increasing engine responsiveness
One of the latest developments is turbo-charged engines, which make it possible to deliver higher engine performance while meeting the new emission standards by integrating the charge air cooler (CAC) into the air intake manifold (AIM); thus, creating a more effective way to cool the air. This increases the temperature in the AIM (up to 230°C), as well as the mechanical requirements for the materials used.
When integrating the CAC into the AIM, the length of pipe previously needed to reach the air-to-air cooler in the front of the car is decreased, which increases engine responsiveness. Thanks to this development, automobile manufacturers can meet India’s emission standards while producing higher performing engines.
DSM offers materials for air intake manifolds that have either an integrated liquid-cooled CAC or an air-to-air CAC. The portfolio of thermoplastic products includes Akulon® polyamide 6, Akulon Diablo® polyamide 66, and Stanyl® and Stanyl Diablo® polyamide 46.
Diablo technology, invented and patented by DSM, is engineered specifically for elevated continuous-use temperatures of 180-230°C. The new Stanyl Diablo HDT2700 has an improved HDT. The melting point in combination with the Heat Deflection Temperature (HDT) gives a good impression of the peak temperature resistance under loads.
Stanyl Diablo HDT2700 and OCD2100 exhibit excellent mechanical strength to provide best-in-class weld strength and ensure part integrity under pressure pulsation loads. It maintains high stiffness even when exposed to continuous-use temperatures up to 230°C and tested up to 3,000 hours.
The new Akulon Diablo HDT2500 withstands a 220°C continuous-use temperature and has HDT of 245°C. When looking at long-term heat aging, the grade has a stable performance up to 220°C tested up to 3,000 hours. Akulon Diablo fills the gap between Akulon PA6 and Stanyl Diablo by combining long-term heat aging performance and mechanical properties at 180-200°C.

How to survive the structural PA66 shortage
Under current market conditions, the supply chain for polyamide 66 (PA66) is under pressure. With the surge in demand for developing lightweight vehicles and pushing the connectivity revolution forward, supply is too concentrated to reliably meet global demand.
