brand pulp is a highly fibrillated chopped fibre that is applied as specialty additive to enhance perfomance by helping to provide excellent reinforcement and viscosity control under shear stress. Kevlar® 1F1710 can be used, inter alia, in automotive brake pads, gaskets, and automatic transmission papers.
