Hybrid eases PEEK flow

US-based Hybrid Plastics has introduced a new version of its POSS Flow nanocomposite masterbatch designed to aid processing of PEEK resins.

PEEK POSS Flow is a pellet-form masterbatch based on Hybrid’s polyhedral oligomeric silsequioxane (POSS) nanomaterial additive technology delivered in a PEEK carrier resin. It is formulated for use at addition levels of between 10 and 20%.

In injection moulding applications, POSS Flow technology is claimed to result in reduced moulding pressures and improved flow. In extrusion, processors are said to see reduced screw torque and higher outputs.

The company claims adding 20% of the additive to high molecular weight PEEK almost doubles the MFI.
