At the Chinaplas 2014 tradeshow in Shanghai, the polymer and rubber supplier Addivant announced three additions to its Polybond polymer modifier product line. The Polybond 7200 coupling agent offers polyolefin processers superior levels of performance in adhesion and filler coupling, while the Polybond 3249 and 3349 coupling agents use halogen-free flame retardants (HFFR) that allow wire and cable compounders to optimize physical polymer properties.

When used in conjunction with Mg(OH)2 or ATH halogen-free flame retardants, Addivant says its Polybond 3249 and 3349 coupling agents allow wire and cable compounders to focus on physical property optimization while achieving excellent flame retardant dispersion and melt flow stability. Applications include building wire, communications cable and automotive wire and cable applications.

The company says that both new grades offer compounders a choice of performance and, depending on final design requirements, the option to select the Polybond grade that delivers the most synergy in their overall system. The Polybond 3249 and 3349 coupling agents are optimized to offer superior physical property retention and melt flow stability. When combined with Addivant’s portfolio of antioxidants and UV stabilizers, wire and cable producers can also leverage Addivant’s expertise across much of their formulation, contends the company.

Additionally, the company notes that its Polybond 7200 coupling agent is designed to deliver optimum dispersion and physical properties in natural-fiber, reinforced polyolefin applications such as injection-molded automotive parts, profile extrusion and laminated packaging. Recent customer trials have confirmed the effectiveness of the coupling agent, with processors achieving the highest level of performance in adhesion and filler coupling. Addivant says the Polybond 7200 polymer modifier is now seeing strong adoption in many markets around the world.

Addivant contends that its Polybond polymer modifiers offer a wide range of benefits to polyolefin customers, in many applications, including: increased efficiency of natural-fiber fillers; improved strength and impact performance in glass-filled applications; enhanced adhesion properties in polypropylene film applications; and more uniform dispersion of fillers and increased adhesion in many composite structures.

“Addivant’s polymer modifier business is continuing to focus on the needs of the polymer market and our customers, as seen in our new capacity investments, extensive recruitment to support our accelerating growth and innovation and in new product development across all our business units,” says Adam Watson, Addivant's business development manager for polymer modifiers. "These three Polybond coupling agents represent the beginning of a planned series of new product launches in our polymer additives business."
