Deltech Monomers para-tertiary-Butyl Styrene (TBS)
Chemical Name:
4-tert-Butylstyrene, (1,1-Dimethylethyl)ethylbenzene, 3-tert-butyl-styrene
Chemical Family:
Styrenics
Deltech para-tertiary-butyl Styrene (TBS) is a versatile substitute for styrene monomer, offering improved properties and fewer handling restrictions. It exhibits low volume shrinkage during polymerization, a high affinity for oils, high solvent receptivity, and improved water resistance in copolymers. From an environmental perspective, TBS has a low vapor pressure and high flash point, reducing emissions from storage or handling and minimizing the flammability hazard. Moreover, its low volatility decreases monomer fumes in the workplace, and it is not classified as a listed air toxic, thus avoiding many environmental use requirements.

Deltech Monomers Vinyl Toluene (VT)
Chemical Name:
Vinyltoluene
Chemical Family:
Vinyls, Vinylics & Vinyl Derivatives
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 Monomers para-Methylstyrene (PMS)
Chemical Name:
3-Methylstyrene, p-Methylstyrene
Chemical Family:
Styrenics
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.

Deltech Monomers Divinylbenzene 80% (DVB80)
Chemical Name:
Ethylstyrene, Divinylbenzene
Chemical Family:
Vinyls, Vinylics & Vinyl Derivatives
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.

Deltech Monomers Divinylbenzene 63% (DVB63)
Chemical Name:
Ethylstyrene, Divinylbenzene
Chemical Family:
Vinyls, Vinylics & Vinyl Derivatives
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.
