Cologne – At K 2019, the international trade show for plastics and rubber taking place in Düsseldorf, LANXESS will be showcasing new masterbatches for manufacturing reinforced rubber parts. The pre-dispersed additives from the Rhenogran product series are easy to handle, dust free, simple to dose, and also exhibit outstanding processing properties.
“The short-fiber aramid pulp in the Rhenogran P91-40 types provide exceptional reinforcement. They improve dimensional stability and extend the service life of the end products that use them,” explained Dr. Benjamin Bechem, head of Global Marketing for Technical Rubber Goods at LANXESS’ Rhein Chemie (RCH) business unit. Aramide fiber masterbatches have previously been available in natural rubber, EPDM, NBR and CR matrices. These can also be used in IR, BR, SBR and HNBR, making them virtual all-rounders. New additives pre-dispersed in silicone rubber (Q) and fluorinated rubber (FKM) are filling in the remaining gaps. “For our next step, we are planning to develop masterbatches of this kind for use beyond rubber as well, such as for thermoplastic polymers,” added Bechem.
