  • Applications

    Polymerization of vinyl chloride: emulsions and suspension of peroxides are more and more accepted in the market. Why to use aqueous emulsions or suspensions? Safety reasons, Solvent free: no contamination of the VCM recycle stream, enhancement of PVC purity, easily to use (pumpable) in ‘closed reactor technology’ and easily to dilute with water. Trigonox EHP-W40S can be diluted with water provided agitation is used to prevent possible phase separation. To melt the solid Trigonox EHP-W40S dilution with water is the most elegant way. Short term stability of Trigonox EHP-W40S or the dilution is sufficient enough to allow handling at temperatures up to 5°C for a short time. Trigonox EHP-W40S is used for the suspension polymerization of vinyl chloride in the temperature range 40-65°C. In practice, Trigonox EHP-W40S is often combined with other peroxides to increase reactor efficiency.
