New Patent for HallGreen Modifiers from HallStar

May 8, 2012

 

The HallStar Company was awarded U.S. Patent Number 8,158,731, titled “Biopolymer Compositions Having Improved Flexibility,” from the U.S. Patent and Trademark Office (PTO) on April 17, 2012. The patent applies to novel, bio-based polymeric additives, which are derived from renewable feedstocks and provide unique benefits to biopolymer processors.

 

Of particular note, HALLGREEN R-8010 is a new, bio-based polymeric succinate that improves the flexibility and pliability of biopolymers including polylactic acid (PLA), starch-based polymers, polyhydroxyalkanoate (PHA), and polyhydoxybutyrate (PHB); while maintaining long-term compatibility.

 

"Brittleness can be a real problem with biopolymer products," said Robert Hu, HallStar Vice President, R&D. "HALLGREEN R-8010 enhances the flexibility and pliability of compounds and end products, and it provides tangible benefits at customers’ manufacturing facilities by increasing throughput and reducing energy consumption."

 

Test results show that performance benefits can be seen at concentrations as low as 10 percent. When used at 30% loading levels, HALLGREEN R-8010 provides performance benefits that include:

•Tenfold increase in elongation percentage at break

•Five-percent reduction in tensile strength

•Five-percent reduction in tensile at break

 

In addition, HALLGREEN R-8010 increases the melt flow index, which can increase throughput and reduce melt temperature and energy consumption in customers' manufacturing facilities.

 

“The HALLGREEN line has become the go-to modifiers for customers that need environmentally friendly esters,” said John Paro, HallStar Chairman, President, & CEO. “As industry continues to develop and improve sustainable products, we expect the reliance on our high-performance renewable ester plasticizers will continue to grow.”
