W1B is prepared by grafting maleic anhydride by POE reaction. Since it introduces a strong polar side group (maleic anhydride) on the main chain of POE molecule, maleic anhydride grafted POE can become a polar material. A bridge for adhesion and compatibility with non-polar materials. In the application of nylon + glass fiber modification, it can react with the glass fiber after surface treatment to improve the compatibility of nylon and glass fiber, thereby improving the tensile strength and impact strength of nylon. W1A can be used as both a compatibilizer and a toughening agent. As a nylon compatibilizer, it is also suitable for PA/PE and PA/PP alloys, which can improve the toughness of the alloys. W1B is an ultra-low temperature toughening agent. The impact strength of PA6+20%W1B at -40℃ can be maintained at 70-80% of normal temperature impact.

As can be seen from the above figure, the product has a good low temperature toughening effect on nylon between -40 and -50, and the notch impact rejection rate at low temperature is very high.
W1B is ethylene elastomer with functionalized maleic anhydride,which is especially suitable for super-tough or cold-resistant nylon.
1. Be used for PA6 or PA66 compatibilizing or toughening. Increase the impact resistance and processability of nylon,decrease the water absorption,greatly improve the cold-resistance.
2. Be used for the compatibilizer of nylon and polypropylene/polyethylene alloy.
3. Be used for the macromolecular modifier(couling agent)of mineral-filled or grass-flber-filled nylon.
