Application

Mainly used as a comonomer for synthesizing resins, the resulting copolymers are widely used in industries such as coatings, textiles, leather, adhesives, etc; Used for the synthesis of plastics and resins; Ethyl acrylate is an intermediate in the preparation of carbamate insecticide carbofuran. It can also be used as a raw material for protective coatings, adhesives, and paper impregnation agents. Its polymer can be used as an anti cracking agent for leather, and its copolymer with ethylene is a hot melt adhesive. Its copolymer with 5% chloroethyl vinyl ether is a synthetic rubber with good oil resistance and heat resistance, which can replace nitrile rubber in some cases.

GB 2760-1996 allows the use of edible spices. It is mainly used to prepare essence such as rum, pineapple and assorted fruits.
