Mannhein, Germany – The new product line under the trade name BioAdimide™ of the Rhein Chemie’s Engineering Plastics Division enables the production of renewable, bio-based polymers for durable applications with a lower environmental impact.

BioAdimide™ additives are specially suited to improve the hydrolysis resistance of bio-based polyester, specifically polylactide (PLA), and to expand its range of applications.  Currently, there are two BioAdimide™ grades available.  The BioAdimide™ 100 grade improves the hydrolytic stability up to seven times that of an unstabilized grade, thereby helping to increase the service life of the polymer. In addition to providing hydrolytic stability,  BioAdimide™ 500 XT  acts as a chain extender that can increase the melt viscosity of an extruded PLA 20 – 30 percent compared to an unstabilized grade, allowing for consistent and easier processing.

“By hydrolytically stabilizing PLA, you open up the possibility to make PLA a suitable candidate for durable markets previously out of reach,” says Don Stengel, Group Manager of Rhein Chemie’s Engineering Plastics Division in the US. “By improving the melt viscosity of an extruded PLA, you make it more stable and easier to process in extrusion, blow-molding or filament applications.

The two grades can also be combined, providing both hydrolysis stabilization and improved processing, for an even broader reach of applications.

The BioAdimide™ line comes out of Engineering Plastics’s Global Product Development Group that has been researching plastics additives for more than 25 years, and continues to explore new areas of polymer stabilization development to meet the market’s growing demands.

Rhein Chemie’s Engineering Plastics Division has already introduced its new line of plastic additives at this year’s Bioplastics Compounding & Processing international conference in Miami, Florida, on March 29 and 30.

About Engineering Plastics Division
Additives from the Engineering Plastics Division are used to protect polymers from hydrolysis and the premature aging associated with this process.  The company’s product portfolio also includes catalysts and activators for the manufacture of cast nylon and modifiers that improve the impact resistance of polyamides.  In addition, highly developed catalysts, crosslinking agents and stabilizers from Rhein Chemie are used in the manufacture of flexible and rigid polyurethane foams.
