DSM Engineering Supplies companions with Renault on light-weight and decomplexed PHEV gasoline tank


DSM Engineering Supplies has partnered with Renault to create an industry-first light-weight resolution for hybrid automobile gasoline tanks. Through the use of Akulon Gas Lock, DSM’s high-performance low-carbon-footprint PA6 (polyamide 6) materials, the gasoline tanks could be produced with a blow molding monolayer building that considerably reduces weight and price with out compromising security or risking extra emissions.

The gasoline tank is designed and manufactured by DSM Engineering Materials undertaking companions RM Applied sciences and MTS France.


As e-mobility continues to develop, laws and requirements are evolving alongside the {industry}. European Union laws set a most CO2 emission fee of 95 g/km for passenger vehicles, which necessitates a cautious steadiness of supplies and design to maximise gasoline effectivity. Historically, gasoline tanks have been product of metal to stop risky compounds from escaping, however these tanks add vital weight to the automobile. Hybrid automobiles allow using smaller gasoline tanks, making a polymer resolution extra viable, however high-density polyethylene (HDPE) nonetheless requires multilayer constructions with complicated extra options to stop permeation, and stand up to the prolonged intervals of inside strain inherent to Plug-in hybrid automobiles.

Following the profitable growth of the primary automotive gasoline tank in polyamide commercialized on the Alpine A110, DSM Engineering Supplies continued its partnership with RM Applied sciences, MTS France and Renault to create an answer for the Renault CAPTUR E-Tech Plug-in-Hybrid, drawing on its portfolio of high-performance supplies to enhance Renault’s gasoline programs engineering experience.

DSM’s modern Akulon Gas Lock materials allows a light-weight monolayer gasoline tank with the low permeation properties wanted to satisfy laws.

Akulon Gas Lock PA6 grades are designed for injection or blow molding and extrusion, making them extremely versatile for the speedy design innovation of the e-mobility sector. Extraordinarily excessive parison stability allows very slender wall thickness distributions, and strong efficiency at each excessive and low temperatures ensures that security is all the time paramount.

Akulon Gas Lock is providing a drop-in resolution and a second life to the monolayer blow molding machines devoted to the manufacturing of the declining diesel monolayer gasoline tanks.

Working with DSM Engineering Supplies to create our new hybrid automobile gasoline tanks has helped us to take a major step towards offering extra sustainable mobility to our clients in every single place. Hybrid automobiles are certainly a key a part of the transition towards a extra sustainable economic system, and we’re very proud to supply this modern new resolution to the market.
