Cooling Impact-modified

Typical automotive applications include gas cap covers, fan blades, shrouds for cooling systems, gears, fasteners, clips, emission control canisters, oil pans, shields, etc. Toughened polyamides are also used in sports and recreational equipment, lawn and power tool housings and components where impact strength, heat and chemical resistance are the primary criteria for their choice. With an estimated consumption of 25 Mton/y in the USA, impact modified PAs...

Mechanical properties depend not only on the crosslinking method but also on the rate of cooling of the polymer mixture [147, 148]. Polyethylene acts here as an impact strength modifier. The more finely it is dispersed in the bl0 the better arc the resulting mechanical properties [149].
