RTP Company has developed new high-flow conductive polypropylene (PP) compounds for thin-wall injection moulding, which has become increasingly important for producing complex medical, electronic and biotechnological devices. Thin-wall parts have a restrictive flow path leading to narrower processing windows, and the need for speciality thermoplastic materials. When existing materials cannot consistently fill thin-walls or difficult geometries, the new high-flow, conductive PP offers a feasible solution without the need to modify tooling or part design. The easy-to-mould, conductive PP materials achieve typical melt flows of 20 g/10 minutes (2160 g at 230C), which compare favourably with existing conductive PP materials (melt flows ranging from 1 to 3).
The materials have been specially designed to minimise warpage and retain their robust physical properties with a notched IZOD impact strength of 2.5 ft-lbs/in (133 J/m) and a ‘no break’ unnotched IZOD impact strength. These tough compounds offer a surface resistivity of 104 ohms/square (maximum) and volume resistivity of less than 25 ohm-cm. Applications include containers, totes, bins, pipette tips and explosives handling products.
