The free-flowing granules are suited for reducing mixing times when producing particularly high-quality hoses or cable sheathings. The first grades to be available are 500, 600, 700 and 800PXL, with vinyl acetate contents of between 50 and 80%.
LANXESS says their process of reactive extrusion ensures that all Levapren PXL granules have the same crosslinking density. The result is free-flowing EVM granules that are quick and easy to process in an internal mixer or in continuous mixing processes and are claimed to deliver exceptional flow properties.
The rubbers in the Levapren PXL series are also said provide higher green strength than standard and XL grades and are less susceptible to blocking even after long-term storage, keeping the material free-flowing.
