How should the flexibilizer be chosen according to the use?

Flexibilizer           is a kind of additive which can reduce the brittleness of composites and improve the impact resistance of composites. It can be divided into two types: active toughening agent and inactive toughening agent. Active toughening agent refers to the active group on its molecular chain that can react with matrix resin. It can form a network structure and increase a part of the flexible chain, thus improving the impact resistance of the composite. The inactive toughening agent is a kind of toughening agent which is well soluble with the matrix resin but does not participate in the chemical reaction.

Selection method:

1, the epoxy adhesive is used for the use of carboxyl liquid NBR, carboxyl liquid NBR, polysulfide rubber, liquid silicone rubber, polyether, polysulfone, polyimide, nano calcium carbonate, nano titanium dioxide, etc.

2. Phenolic resin adhesive can be selected from carboxylic nitrile rubber, liquid nitrile rubber, polyvinyl butyral, polyethersulfone and polyphenylene ether ketone. Water soluble phenolic resin is carboxylic nitrile latex and polyvinyl alcohol as toughening agent.

3. Quick setting acrylic structural adhesives often use acrylic rubber, carboxylic nitrile rubber, chloroprene rubber, chlorinated sulfonated polyethylene, ABS resin, etc.

4, acrylic cyanoacrylate adhesives should be selected with acrylic rubber, ABS, SBS, SEBS and so on.

5, unsaturated polyester resin adhesive should choose liquid nitrile rubber, polyvinyl butyral, polyvinyl acetate and so on.

6. Urea formaldehyde resin adhesive can be selected as polyvinyl acetate emulsion, polyvinyl alcohol and so on.
