Introduction of Toughener

Toughener is a kind of additive which can reduce the brittleness and improve the impact resistance of composites. It can be divided into active toughening agent and inactive toughening agent, the active toughening agent refers to its molecular chain contains active group can react with the matrix resin, it can form a network structure, increase a part of the flexible chain, so as to improve the impact resistance of composite material. Inactive toughening agent is a kind of toughening agent which is compatible with matrix resin but does not participate in chemical reaction. For example, W1A and other products produced by our company belong to the active toughening agent, which has a good effect on nylon toughening.
