TLV-TWA 10 ppm (～35 mg/m3) (ACGIHand MSHA), TLV-TWA skin 10 ppm(～35 mg/m3) (OSHA); IDLH 1000 ppm(NIOSH).physico-chemical propertyColorless volatile liquid. It has a pungent smell and a tear-jerking effect. Soluble in ethanol, ether, acetone and benzene, slightly soluble in water.product useOrganic synthesis intermediate, is also the synthesis of polymer monomer. The rubber copolymerized by methyl acrylate has good resistance to high temperature and oil. The spinnability, thermoplasticity and dyeing properties of acrylonitrile can be improved by copolymerization with acrylonitrile. It can be copolymerized with methyl methacrylate vinyl acetate or styrene to produce coating and floor polish with good properties. It is also widely used in pharmaceutical manufacturing, leather processing, paper making, adhesive manufacturing and so on.securityMethyl acrylate has moderate toxicity, has strong irritation and corrosion effect on eyes, skin and mucosa, and can be absorbed through the skin to cause poisoning, rat oral LD50 is 300mg/kg. Rabbit oral LD50 280mg/kg. Symptoms of chronic poisoning include headache, drowsiness, spasm of hands and feet, etc. The maximum allowable concentration in the workplace is 35mg/m3. Ventilation should be enhanced in the operating place. Operators should wear protective equipment such as rubber gloves, face masks and protective clothing. Poisoning should be immediately moved to a well-ventilated place to rest, take glucose and vitamin B, C, etc.

Packed in galvanized iron drums. Should be stored separately, to prevent direct sunlight, storage temperature <21℃, long-term storage and transportation should be added to resist polymer. Pay attention to fire prevention. Store and transport in accordance with flammable provisions.
