Expansion lets compounder add rigid PVC to its offerings

Expansions slated for two of its facilities means thermoplastics compound supplier Teknor Apex Co. will increase its supply capabilities for both rigid and flexible polyvinyl chloride compounds. The company has long offered flexible PVC compounds in the U.S., but rigid PVC compounds are new for the firm there. The company, based in Pawcatuck, RI, plans in August to add a new flexible PVC compounding line with a nominal annual capacity of 13,600 tonnes (30 million lb) to its site at Fountain Inn, SC.

At its facility in Brownsville, TN, the company plans to convert a compounding line that had been dedicated to flexible vinyl into one that can yield either rigid or flexible PVC. The swing line will enable Teknor Apex to accommodate a growing number of customers who use both rigid and flexible vinyl and prefer to be serviced from one facility, according to Louis Cappucci, VP of the compounder's vinyl division.

Added Cappucci, "Flexible compounds with improved melt elasticity are particularly valuable for extrusion processors looking for ways to increase productivity, and rigid compounds represent a promising new product line for Teknor Apex in the U.S."
The company's Singapore Polymer Corp. subsidiary has long produced rigid PVC compounds. Examples of new rigid PVC products developed in the U.S. are gamma-stable medical molding compounds and flame-retardant formulations that can be extruded at very low wall thickness and still meet UL V-0 flame ratings, reports the company.
