Products in Monomers & Oligomers: Thermal Stability

STEPAN® MWA-570 HS is a diethylene glycol-phthalic anhydride-based modified polyester polyol that exhibits hydrolysis resistance and good thermal stability. It exhibits a good hardness/flexibility balance, clarity, and low color. It is used in metalworking formulations for improved lubrication properties and is a great option as a chlorinated paraffin replacement, either alone or with the addition of phosphate esters. It also shows improved lubrication by showing a reduced average scar when compared to the current industry standard.

Neol® Neopentyl Glycol Flakes is a colorless solid at room temperature (approx. 20°C) with a sweet odor. It is a bifunctional alcohol used in the synthesis of the following products: Resins, such as polyurethanes and polyesters Polyols, such as polyesters, polycarbonates and polycaprolactones Plasticizers

Deltech Vinyl Toluene (VT) is a mixture of methylstyrene isomers, with approximately 55% meta and 45% para isomer distribution. This reactive monomer readily polymerizes to form a high-clarity, colorless polymer with excellent electrical and physical properties. In many applications, VT demonstrates superior properties compared to styrene monomer.

Deltech para-Methylstyrene (PMS) is recommended for evaluation as a replacement for vinyltoluene and styrene monomers. It shares similar chemical properties and polymerization behavior with both vinyltoluene and styrene. When used as a partial or complete replacement for styrene monomer in unsaturated polyester resin applications, polymerized resin products exhibit lower vapor pressure at any temperature and a higher flashpoint. Additionally, PMS offers advantages such as lower shrinkage during molding, improved thermal properties, and greater tensile strength in glass-filled applications.

Neol® Neopentyl Glycol Sol. 90% is a colorless aqueous slurry with a mildly sweet odor. It is a bifunctional alcohol used in the synthesis of the following products: Resins, such as polyurethanes and polyesters Polyols, such as polyesters, polycarbonates and polycaprolactones Plasticizers
