It is mainly used in polyethylene film. It is used to treat amylum, talcum powder, calcium carbonate. The products treated by NDZ-131 can obtain excellent thermal stability, foam free when blowing film, improved dispersion, good mechanical performance, reduced melting viscosity of composite material, improved processing, reduced mechanical abrasion and higher productivity. It can be applied to various rubber products to improve tearing resistance, maximum elongation. It can be used in paint to increase filler dosage and reduce viscosity, simultaneously give coat the performances of abrasive resistance and anticorrosion. Magnetic power treated by NDZ-131 can improve dispersion on substrate and adhesion on polymers.
