Vertellus’ (Indianapolis, Indiana / USA; www.vertellus.com) polymers business has introduced three new masterbatches in its “ZeMac” line for enhancing PA compounding processes. The first two, "Extend L65" and "L68" masterbatches, are chain extenders and branching agents that convert low relative viscosity (RV) PA to branched high RV PA with higher mechanical and thermal performance than linear high RV PA. The pair are recommended for use in upgrading recycled or prime polyamide compounds. The third, "Extend P62", is claimed to be currently the only product on the market today that is able to smoothly compatibilise PA and recycled PET.

The company showcased the grades alongside other plastics additives at the recent "K 2016" fair in Düsseldorf / Germany. Vertellus just emerged from Chapter 11 bankruptcy proceedings – see Plasteurope.com of 01.12.2016.
