Diallyl phthalate has a wide range of applications and can be used as a crosslinking agent and plasticizer for unsaturated resins, an internal plasticizer for PVC resins, and a reinforcing agent for fiber resins It can self polymerize as a plasticizer and also serve as an auxiliary crosslinking agent for synthetic rubber. The main applications include:
Synthesis of acrylic resin:
Diallyl phthalate is used for synthetic resins based on acrylic acid, such as printing pastes, waterproof adhesives, etc. It helps improve the adhesion, water resistance, gloss, fluidity, and viscosity of the resin.
Unsaturated polyester resin:
In the production and use of unsaturated polyester resin, Diallyl phthalate can be used as cross-linking agent, internal plasticizer (reactive plasticizer), dispersant of dyes and catalysts, and anti gel agent of vinyl monomers such as styrene. As a crosslinking agent, it has better electrical properties, heat resistance, and dimensional stability than products obtained using styrene as a crosslinking agent. As a dispersant and anti gelling agent, due to its high stability at room temperature, high boiling point, and low volatility, even with catalysts, it is difficult to cure at room temperature and requires heating for curing. So it can be used to produce pre mixed or pre impregnated unsaturated polyester resin, and can also be used for insulation varnish, hardened wood production, etc.
Internal plasticizers for high polymers:
Diallyl phthalate can be used as an internal plasticizer for high polymers, such as for plasticizing polyvinyl chloride, to improve the heat resistance, light resistance, solvent resistance, and electrical properties of products. It is widely used in sealing agents for automobiles, refrigerators, foam wallpapers, artificial flooring, and other applications.
Self polymerized polymers:
Diallyl phthalate is a self polymerized polymer (prepolymer) with excellent heat resistance, plasticization, toughening, and dispersibility. Widely used in molding materials, decorative laminates, UV curable inks, coatings, etc.
