Low temperature resistant nylon toughener (W1A)

W1A is prepared by grafting maleic anhydride by POE reaction. Because it introduces a strong polar side group (maleic anhydride) into the main chain of POE molecule, maleic anhydride grafted POE can become a polar material A bridge of 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.

As a toughening agent for nylon, W1A has excellent low-temperature performance. The impact strength of PA6+15%W1A at -40°C can be maintained at 35-40% of that at room temperature.

W1A is a commonly used compatibilizer in polymer blends, which can improve the compatibility between two or more polymers that are typically immiscible. However, it is not typically used as a toughening agent.

Toughening agents are typically materials that can improve the impact resistance of a polymer, and are often added to brittle polymers to improve their toughness. Examples of toughening agents include elastomers, core-shell particles, and thermoplastic modifiers.

While it is possible that W1A could have some toughening effect on a specific polymer blend, its primary role is as a compatibilizer.
