UMEX Resin Filler Dispersant (Acid-Modified PP)

UMEX is an acid-modified polyolefin resin.
UMEX features a higher degree of modification and lower melt viscosity than other products. Even at low addition levels, it effectively promotes the dispersion of pigments, fillers, wood flour, and other materials in polyolefin resins, making it an excellent dispersant. It also improves adhesion between polyolefin resins and other materials and performs exceptionally well in applications such as hot-melt adhesives and asphalt modifiers.
