The global diallyl phthalate resin market was valued at approximately USD 1.2 billion in 2023 and is projected to reach around USD 2.0 billion by 2033, reflecting a compound annual growth rate (CAGR) of about 5.8%, according to Verified Market Reports. Diallyl phthalate (DAP) is a cross-linkable monomer and resin used in high-performance molded parts, electrical components and glass-reinforced composites.

Diallyl phthalate resin serves in electrical and electronic molded parts, in automotive and industrial components, and in glass-reinforced and high-temperature composites. Demand is tied to the expansion of high-performance electronics and electric vehicles, the growth of aerospace and defense applications, and the rising use of DAP in precision-molded connectors and insulators. Asia-Pacific is the fastest-growing region, supported by extensive electronics and automotive industries in China, India and Southeast Asia.

North America and Europe sustain steady demand in premium electrical and aerospace applications. Continued high-performance growth positions diallyl phthalate resin as a steadily advancing cross-linkable monomer.
