CAS RN: 25013-15-4
Physical and chemical properties: Appearance: colorless liquid
Flash point: 53℃
Boiling point: 170-172 ℃
Density (20 oC): 0.897-0.899 g/cm³
Characteristics: flammable, reactive with oxidants, peroxides and strong acids.
Applications: VT is a mixture of m-methylstyrene and p-methylstyrene. Compared with styrene monomer (SM), it has lower toxicity, volatility and odor, higher stability and flash point. It can be used as a replacement of SM for the manufacture of unsaturated polyester resin, modified alkyd resin, vinyl resin and so on. These resins are widely used in impregnating insulation paint, coating and composite industries.
