Custom manufacturer of thermoplastic elastomers, GLS, introduced the DYNALLOY line for injection molding and blow molding grades based on olefin block copolymers from Dow Chemical.

Here at Kunstoffe 2007, Germany, GLS Corp., a global leader in the development, manufacture and supply of high-performance, custom-formulated thermoplastic elastomers (TPEs), introduced a new family of TPEs based on INFUSE** olefin block copolymers (OBC) from The Dow Chemical Company. The new DYNALLOY* OBC injection-molding and blow-molding grades allow GLS to offer customers a broad array of standard and customized TPE alloys for a wide range of applications. With the new DYNALLOY line, GLS has expanded the existing property and application range of OBC technology with exceptional softness, unique feels, a wider range of flow characteristics in injection molding, and introduced a new blow moldable grade range. DYNALLOY OBCs offer a silky soft touch feel, excellent colorability, isotropic shrinkage, and flow characteristics enabling use in complex molds with long flow paths.

Walter Ripple, vice president of global sales and marketing for GLS Corp., stated, “We are very pleased to be selected by The Dow Chemical Company as a global thermoplastic elastomers compounding partner to help them expand the application range of their newly introduced INFUSE olefin block copolymers. This new class of TPEs are a significant complement to GLS’s portfolio of customizable materials, and offer huge potential for both standalone and overmolding applications. They enable us to offer customers thermoplastic elastomers characteristics that were not previously available.”

The five standard injection-molding grades of DYNALLOY OBC thermoplastic elastomers include opaque and translucent materials and provide hardness levels ranging from 60 Shore A down to a gel-like 5 Shore A. They offer excellent colorability as well as a non-tacky, soft touch feel that avoids dust pick-up. Other performance highlights include improved compression set and creep resistance. In addition, GLS utilized the unique rheology characteristics of OBC to formulate a unique soft feel and flexible blow-molding grade with a 50 Shore A hardness that can be customized for higher or lower softness to meet specific market needs.

In addition to property enhancements, GLS’ new line of DYNALLOY OBCs can be formulated for optimized flow characteristics to fill complex molds with long flow paths, providing a unique isotropic shrinkage characteristic. Most grades are suitable for two-shot and insert overmolding with polypropylene.

Target markets include consumer and office products, hardware, food packaging, and medical for applications such as comfort grips for writing instruments, cosmetic items, prosthetics and overmolding applications with fabric.

The six thermoplastic elastomers grades listed below will be featured at GLS’ booth at Kunstoffe 2007 (Hall 8A / D08). They are commercially available worldwide.
