CPCs are considered most often for injection molding. However, they also can provide the same benefits to extrusion processors.

WEB EXCLUSIVE: A brand-new purging agent from Sun Plastech Inc., Parsippany, N.J., is designed for purging high-temperature engineering resins such as PEEK, PPS, Ultem PEI, and LCP from injection machines and extruders.

It’s safe to say that the concept of using a commercial purging compound (CPC) has largely been embraced by the plastics processing community.

In our September issue, we incorrectly stated (p. 17) that Asaclean U high-performance purging agent is not suitable for polypropylene.

New purging agents from three companies were exhibited at NPE in Chicago.

An enhanced version of a commercial physical purging agent is said to provide even better cleaning power than the previous version while reducing the amount of residue left behind by 30% or more.

Compounders, molders, and extruders will be treated to a wide range of new additives at NPE 2006.

A dramatic demonstration of the economic value of efficient machine purging-especially in these days of high resin prices-was obtained from a commercial test at a U.S. injection molder.
