LAN-XESS Rhenogran WPD-70/SBR Processing Aid

LAN-XESS Rhenogran WPD-70/SBR Processing Aid is a high-performance polymer processing aid designed for styrene-butadiene rubber (SBR) compounds. It enhances dispersion, reduces mixing energy, improves filler incorporation, and boosts extrusion efficiency while maintaining vulcanizate properties. Ideal for tire treads and industrial rubber goods, this masterbatch delivers consistent rheology control and superior process stability in high-shear applications.
