5000L SS316L Jacketed Chemical Reactor for Unsaturated Polyester Resin and Gelcoat Production

SS316L Jacketed Chemical Reactor for Unsaturated Polyester Resin Gelcoat and FRP Composite Resin Synthesis

Vison Chemicals manufactures SS316L jacketed chemical reactors for synthesizing unsaturated polyester resin through the polycondensation of diols, dibasic acids and styrene. The reactor controls the esterification, condensation and styrene dilution stages with precise jacket temperature and vacuum control, delivering clear, high-solid UPR resin for gelcoat, FRP composite, artificial marble and polyester putty applications. A corrosion-resistant SS316L vessel with anchor and paddle agitation ensures uniform heat transfer, fast reaction and consistent batch quality for polyester resin producers.

Key Features

• Jacketed SS316L reactor with thermal oil, steam or electric heating holds the polycondensation temperature window for unsaturated polyester resin and gelcoat synthesis
• Reflux condenser and vacuum dehydration system strip water and glycols during polyester resin esterification and condensation
• Anchor, paddle and multi-stage impeller agitation with baffle keeps the viscous polyester resin homogeneous and prevents local overheating
• Double mechanical seal and full-vacuum-to-6-bar design pressure for safe styrene dilution and vacuum operation during UPR resin production
• Corrosion-resistant SS316L wetted surfaces withstand acidic polyester resin reaction media and maleic and phthalic anhydride feedstocks
• Mirror-polished interior and bottom discharge valve allow fast batch changeover and easy cleaning between gelcoat and clear casting resin grades
