Achieving Enhanced Flexibility and
Strong Adhesion in Polar Resins
TUFTEC™ M1981 is a maleic anhydride grafted SEBS. It can be used as an impact modifier and compatibilizer for polar resins and engineering plastics such as polyamide (PA). It has the lowest hardness in the series and can further enhance the flexibility of polar resins. It also exhibits excellent compatibility with polypropylene (PP), making it suitable for use as a compatibilizer between PP and polar resins.
