III. Application: 

Acrylic acid:
used to produce acrylic ester, polyacrylic acid and salt.

Methyl acrylate: used for the second monomer of polyacrylonitrile fiber and adhesion agent.

Ethyl acrylate: Mainly for various adhesion agents in fabric processing and the main raw material for producing acrylic rubber. 

N-butyl acrylate: used for organic intermediate, binding agent, emulsifier and painting.

IV. Packaging: 

Acrylic acid: Generally with 220PPm polymerization inhibitors; the product is stored in a shady, cool and ventilated warehouse and should keep far away from tinder and heat sources; product packaging shall be sealed as required. The temperature in the warehouse should not be higher than 25℃ and lower than 15℃. Due to its corrosiveness, acrylic acid can be stored only in glass containers, stainless steel containers or polyethylene-lined containers; polyethylene-lined containers can be used only for short-term storage. 

Methyl acrylate: Generally with 15PPm polymerization inhibitors; the product is stored in a shady, cool and ventilated warehouse and should keep far away from tinder and heat sources; product packaging should be sealed as required. The temperature in the warehouse should not be higher than 25℃. 

Ethyl acrylate: Generally with 15PPm polymerization inhibitors; the product is stored in a shady, cool and ventilated warehouse and should keep far away from tinder and heat sources; product packaging shall be sealed as required. The temperature in the warehouse shall not be higher than 25℃.

N-butyl acrylate: Generally with 15PPm polymerization inhibitors; product is stored in a shady, cool and ventilated warehouse and should keep far away from tinder and heat sources; product packaging should be sealed as required. The temperature in the warehouse should not be higher than 25℃.

V. Storage and transportation: Three packaging and transportation modes including train tanker, automobile tanker and barrel (200L).
