Stanyl PA46 offers significant benefits for overmolded parts

01-Apr-09

PVS-Kunststofftechnik, a German company specializing in overmolded insulation and other precision parts such as cooling fans for the electronic industry, has employed DSM's Stanyl® PA46 for the stator of the latest electric waterpump produced by Pierburg (Germany), the world's first series-production supplier of electric coolant pumps. Replacing powder coating and paper insulation, overmolding is a relatively new technology and is said to provide value trough the possibility of adding 3D geometry and environmental benefits whilst saving processing time and reducing the number of steps in production. Overmolded insulation is a new application area for Stanyl PA46, which is available in standard, HF (HighFlow) & SF (SuperFlow) grades. This is the first time Stanyl PA46 has been used in overmolding application. The material was used due to its elevated temperature resistance, dimensional stability, excellent flow properties, heat dissipation and design freedom. Stanyl TE250F6 PA46 grade, used for the application, is a 30% glass-reinforced, heat-stabilized and flame-retardant formulation. It is typically specified for applications that benefit from its 180+C temperature resistance, good dimensional stability, low creep, high modulus, good in-mold flow, and ability to meet regulatory requirements.
