For a company that was mothballed by DSM, and then resurrected in 2006, Polyscope is doing well. Or rather more than well, says Director of Sales and Business Development Peter Tackx. "We started in 2006 with nothing, and we've built that into an operation that generates some 40 million euros in sales annually," he said. "What we do, the class of polymers we make, is actually quite unique," he added.
So what does Polyscope do? It's one of only a very few in the world to produce specialized styrene maleic anhydride functionalized copolymers and terpolymers, that serve as compatibilizers in styrenic systems and high-heat promoters for styrenic compounds. "Our products are copolymers, which means that the maleic acid is actually in the polymer, not grafted onto it," explained Tackx. "This means that our products offer a much higher concentration of MA. Systems in which the maleic acid is grafted onto a matrix are used for compatibilizing polyolefins. Our system is suitable for styrenics."
Polyscope has developed a product line called Xeran that is suitable for compatibilizing numerous compounds. The presence of maleic anhydride monomers in the chain makes these products reactive towards polyamides, polyesters and polycarbonates. Hence, the Xeran grades can be used to compatibilize compounds of polycarbonate (PC) and acrylonitrile butadiene styrene (ABS) or acrylonitrile styrene acrylate (ASA), compounds of polyamide (PA) and ABS and compounds of polybutylene terephthalate (PBT) and ABS or ASA. Polyscope even offers a Xeran coupling agent to enhance performance of styrene acrylonitrile (SAN) with glass fibers.
