Teknor Apex develops new range of bioplastics compounds based on thermoplastic starch blended with conventional polymers including PP, LLDPE, and biodegradable copolyester

LOS ANGELES , November 27, 2009 () – Teknor Apex Co.’s bioplastics division has developed a new range of bio-based compounds, Plastics Additives and Compounding reported Nov. 26.

The Terraloy compounds are made from thermoplastic starch (TPS) blended with conventional polymers including polypropylene (PP), linear low density polyethylene (LLDPE), and biodegradable copolyester.

The Pawtucket, Rhode Island-based company manufactures the compounds from a process developed by Montreal, Quebec-based Cerestech Inc., which converts starch granules from corn, wheat, tapioca, or potatoes into a masterbatch containing TPS and a host polymer.

When mixed with another bioplastic or a biodegradable copolyester, the resulting compound is reportedly fully biodegradable.

The Terraloy range will be offered in ready-to-process compound and masterbatch form.
