New polyamides for blow moulding

摘要

Akulon Fuel Lock FL40-HP from Netherlands-based DSM Engineering Plastics is a polyamide 6-based material designed for blow moulding into off-road fuel tanks. These are used for engines powering handheld and ground-supported lawn and garden equipment, as well as recreational, professional landscaping and marine applications. Tests on the material are said to yield hydrocarbon permeation rates less than 5% of the maximum value of 2.0g/m~2/day allowed for these applications by Cali-fomian state regulations. This represents a reduction of evaporative emissions from small-engine fuel tanks of more than 99% as compared with high-density polyethylene (HOPE).
