High-flow conductive polypropylene compounds for thin-wall injection moulding, which has become increasingly important for producing complex medical, electronic and biotechnological devices.
RTP has developed 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 high-flow, conductive PP is viable without the need to modify tooling or part design.
The easy-to-mould, conductive PP materials achieve typical melt flows of 20g/10min (2160g at 230C), which compare favourably to existing conductive PP materials (melt flows ranging from one to three).
The materials have been designed to reduce warpage and retain their robust physical properties with a notched Izod impact strength of 133J/m and a no-break unnotched Izod impact strength.
These tough, highly conductive compounds offer a surface resistivity of 10E4ohm/square (maximum) and volume resistivity of less than 25ohm-cm.
Applications include containers, totes, bins, pipette tips and explosives handling products.
