Resin Manufacturing

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.

DIEB (Di-Ethylbenzene) is a clear amber liquid with excellent stability. This product is widely used in multiple applications, including lubricating oils, heat transfer fluids, and the manufacturing of synthetic rubber and resins. It is intended for commercial and industrial applications requiring consistent and high-performance characteristics. DiEB serves as a raw material for various uses and has an odor characteristic of aromatic hydrocarbons.

Deltech Divinylbenzene 63% (DVB63) is a reactive monomer primarily composed of divinylbenzene and ethylvinylbenzene isomers. It is commonly used in the synthesis of ion-exchange resins and in the production of unsaturated polyester resins and casting resins, where DVB63 serves as a cross-linking agent, providing rigidity. The appearance of this product is that of a yellowish-clear liquid.

Deltech Divinylbenzene 80% (DVB80) is an extremely reactive monomer. It appears as a clear to slightly hazy amber liquid and has an odor characteristic of aromatic hydrocarbons. Special care is needed with DVB80, as heat-initiated free radical polymerization can easily occur, making the monomer molecule unstable when heated. To prevent premature free radical polymerization, it is treated with tertiary Butyl Catechol (TBC) as an inhibitor. DVB80 is utilized in various fields, including coatings, adhesive tackifiers, functional polymers, molded composites, and insulating varnishes.
