Maplan, Lanxess cooperate on HNBR moulding systems

ERJ staff report (DS)

Leverkusen, Germany - Lanxess AG and Maplan are working together to get the best from a new grade of HNBR aimed at high speed injection moulding.

The new grade from Lanxess, Therban AT 3400 VP is designed to flow more easily than previous grades of HNBR. Lanxess hopes the cooperation with Maplan will help develop experience in getting the very best from the material, and help customers to improve cycle times and product quality.

At normal processing temperatures, the product has a viscosity of between 100 and 1000 Pascal-seconds. This means it flows 1000 to 10 000 times more easily than existing Therban grades, said Lanxess.

Rudolf Eisenhuber, head of the engineering section at Maplan said the Austrian machine maker approached Lanxess soon after the AT 3400 VP product was launched. He said, "Together we were able to adapt our plant engineering to the properties of the new elastomer within a very short time."

Injection units with a short, permanently tight-fitting cooled nozzle can easily and efficiently make small, thin parts using the Lanxess high-flow grade of HNBR, said the companies.
