PARALOID™ EXL 3691J is a free-flowing pelletized MBS modifier ideal for a wide variety of engineering resin systems requiring increased thermal stability and good colorability in both weatherable and nonweatherable systems.
PARALOID™ EXL additives enhance the impact strength and ductility for injection molding of engineering resins. PARALOID™ EXL 3691J offers good melt flow modulus, lower-temperature toughness, reduced melt viscosity, effective dispersion, and processability. This grade is compatible with polycarbonate, polyesters, and polycarbonate–ABS blends that need improved impact performance at low temperatures.
