| Para-Methylstyrene (PMS) monomer is suggested for evaluation as a replacement for styrene monomer. PMS monomer has chemical properties and polymerization behavior similar to both vinyltoluene and styrene monomers. Applications requiring a single methylstyrene isomer should consider Deltech's PMS monomer which contains 95-97% PMS. Use of PMS monomer as a partial or complete replacement for styrene monomer in unsaturated polyester resin applications results in lower resin vapor pressure at any temperature and a higher flashpoint. Lower shrinkage during molding, higher thermal properties and greater tensile strength in glass-filled applications can be expected from polymerized resin products. |
