Characteristics:
Diallyl phthalate (DAP) is a colorless or light yellow transparent liquid. Each molecule contains two allyloxy groups, it is stable at room temperature, but if under heating and adding some initiator, it will be very reactive, and can be made into many new materials with special usage.
Solubility:
DAP monomer is soluble in most organic solvents, such as ethanol, acetone, ethyl acetate, benzene, toluene and DMSO; slightly soluble in gasoline, ethylene glycol, glycerol and amine; insoluble in water.
Usage:
Process for preparing DAP polymerization solution and DAP resin, also used as cross-linking agent.
DAP has wide application fields. It can be used as cross-linking agent and plasticizer of unsaturated resin, internal plasticizer of PVC resin, reinforcing agent of fiber reinforced resin, it can self polymerized as plastic strengthen agent, also can be as the auxiliary cross-linking agent of synthetic rubber.
Main Usage:
1. Synthesis of acrylic resin, such as waterproof glue.
2. Unsaturated polyester resin, used in the production of insulating varnish.
3. Internal plasticizer for polymer, used in the plasticizer of PVC.
4. self polymerization polymer, used in molding materials.
