Fuel lock enables new solution for rotomoulding monolayer tanks

Paul Boughton

Akulon Fuel Lock, an innovative-polyamide 6 technology developed by DSM, forms the basis of a new solution for rotomoulding monolayer tanks, developed by ICO Polymers, a subsidiary of A Schulman Inc.

The monolayer PA6 solution, named ICORENE 7620 FUEL LOCK, was developed for small engine tanks for off-road vehicles to comply with the latest legislation of the US Environmental Protection Agency (EPA) and the California Air Resources Board (CARB), which was introduced to minimise emissions from fuel evaporation.

ICORENE 7620 FUEL LOCK was launched during the Conference of the Alliance of Roto Moulding Organizations (ARMO), held in Lyon, France. [Page Break]

The new monolayer PA6 solution is based on the successful Akulon Fuel Lock, an innovative polyamide 6 from DSM, originally designed for injection and blow-moulded fuel tanks that are used for engines in hand-held and ground-supported lawn and garden equipment, as well as recreational, professional landscaping and marine applications.

ICORENE 7620 FUEL LOCK eliminates the need for after-treatment procedures such as the environmentally challenging fluorination process. Moreover, this monolayer solution obviates the need for complex multi-layer concepts, delivering improved equipment efficiency and productivity – and therefore lower energy consumption during processing. In use, the monolayer solution ensures a durable barrier performance over the required liability period of five years, and this does not diminish over time.[Page Break]

The easy-to-process toughened polyamide PA6-based monolayer rotomolding (RTM) solution was designed specifically for the production of small engine tanks for off-road vehicles. Its development was made possible by combining ICO Polymers’ expertise in RTM, particle size reduction and processing - and DSM’s leadership in high performance engineering materials.

Besides EPA compliant tanks, ICORENE 7620 FUEL LOCK can be used in any applications that require low fuel permeation, low temperature impact performance and UV stability.
