SCONA 20097: A polypropylene homopolymer grafted with high-purity maleic anhydride. Improved compatibility with the high-polarity polymer EVOH.

SCONA 20097: It is a polypropylene homopolymer grafted with high-purity maleic anhydride. Due to its very low viscosity, it has excellent wetting properties. By blending it, the polarity of polypropylene is increased, improving compatibility with high-polarity polymers such as EVOH. Additionally, it serves as an excellent coupling agent for short and long fiber glass-reinforced polyolefins, enhancing their physical, mechanical, and thermal properties. Furthermore, SCONA 20097 can be used as a coupling agent in natural fiber-reinforced and wood fiber-reinforced composites. This additive has excellent mechanical strength and offers good cost-effectiveness. It also has a very weak odor and low VOC content. PRIEX 20097 is a pellet with good flowability, making it safe and easy to handle.
