CHEMICAL STRUCTURE

INTRODUCTION
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.

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℃.
