Jim Harper, product manager at Hexpol TPE, Sandusky, Ohio, (hexpoltpe. com), addressed bio-based TPEs and new opportunities for sustainable products. Hexpol's Dryflex TPEs are biobased, recy- clable materials with up to 90% renew- able content and a hardness range from 20 Shore A to 50 Shore D. They boast good adhesion to PE, PP, ABS, SAN, PET, and PLA. Harper also discussed new opportuni- ties for sustainable products made of the company's Dryflex Green biobased TPEs, which are based on renewable resources such as plant and vegetable crops. The company has developed compounds with over 90% renewable content and the same hardness range as other Dryflex grades and adhesion to a similar range of materials. Harper showed that these biobased TPEs display mechanical and physical proper- ties comparable to conventional TPEs. The latest Hexpol addition is the DW series of compounds from 50 to 90 Shore A, designed for applications that come into contact directly or indirectly with drinking water, including domestic and commercial applications such as shower heads, plumbing seals, and pipe fittings. Designed for both injection molding and extrusion, they bond to PP and PE in over- molding applications and boast no micro- bial growth without the use of biocides. The latest addition to the Dryflex Green portfolio is the DW series for applications that come into contact directly or indirectly with drinking water. © Branson Ultrasonics Corporation 2017.
