Principal Use
Ethylene glycol dimethacrylate is mainly used in plastic and rubber industries as ethylene- acrylic copolymer, ABS, acrylic acid sheet material, tubing, fiberglass enganced polyester, PVC, ion exchange resin. The polymer containing it has increasing rigidity, heat-resistant, weathering resistance, solvent resistance and improving frictional ability, in addition, ethylene glycol dimethacrylate can be also used as dentistry material, latex copolymer, paper making, rubber modification, adhesive, printing ink, and crosslinking agent of optical polymer.
Packaging
Plastic drums or stainless steel tank,200kg net weight.
Transportation and Storage
Avoid shine rain and high temperature in transportation.Store the products in cool, shady and ventilated conditions, keep far away from fire.6 months from date of delivery at a maximum storage temperature of 30℃.
General hints
Can burn in fire! Polymerization may be initiated by contamination with peroxides, azo compounds, heavy metal ions, tert. Amines, S compounds. Polymerization is also induced by light. Atomospheric oxygen saturation in the monomer is necessary for stability. Storage temperatures should not exceed 35℃.please weare goggles and anti-poison respirator, Avoid contact with skin, eyes and mouth cavity.
