A new range of masterbatches for PVC wire and cable applications are more effective at repelling termites than oils, says developer Clariant

A new range of masterbatches for PVC wire and cable applications are more effective at repelling termites than oils, says developer Clariant.

“Anti-termite masterbatches can be added during the wire-jacketing process simply by dosing them into the stream of natural material at the extruder feedthroat,” says spokesperson Davor Horvat. “It is not necessary to maintain a stock of oil-treated PVC along with the untreated compound, so inventory costs are reduced.”

Oil-based treatments also migrate from the finished product (causing loss of effectiveness), are hazardous and messy to handle, and cannot be introduced directly into the extrusion process, he adds.

The masterbatches are part of the Clariant CESA-antimicro brand and incorporate an EPA-registered pesticide.
