Uses. Plastics and synthetic rubber are the major uses for styrene. They account for the exponential growth from a few million pounds per year in 1938 to more than 8 billion pounds today. The numerous plastics include polystyrene, styrenated polyesters, acrylonitrile-butadiene-styrene (ABS), styrene-acrylonitrile (SAN), and styrene-butadiene (SB). Styrene-butadiene rubber (SBR) was a landmark chemical achievement when it was comrner-cialized during World War II. The styrene derivatives are found everywhere—in food-grade film, coys, construction pipe, foam, boats, latex paints, tires, luggage, and furniture. 

Several other archery bow manufacturers have installed catalyst-heat systems for making wood-plastics but little is known about their production. A number of pilot plant operations have been installed in the United States but little of this proprietory information is available. Pilot plant quantities of cutlery handles have been produced for market studies, a laminated type of flooring was produced using a styrene-polyester composite cured in a hot press, parquet flooring using the catalyst-heat system is presently being produced for market studies. Many other small volume items, such as, jewelry, bird calls, transformer cores, etc. are finding their way into the market place.

Polysulfone A number of adhesives have been found useful for joining polysufone to itself or to other materials. These include 3M Company s EC 880 solvent-base adhesive, EC 2216 room-temperaturecuring epoxy two-part paste, Bloomingdale Division, American Cyana-mid Company BR-92 modified epoxy with DICY curing agent, or curing agent "Z" (both spreadable pastes), vinyl-phenolics, epoxy-nylons, epoxies, polyimide, rubber-based adhesives, styrene polyesters, resorcinol-formaldehyde, polyurethanes, and cyanoacrylates. The EC 880, EC 2216, and the two BR-92 adhesives are recommended by the polysulfone manufacturer. Union Carbide (16) (17).

OTHER COMMENTS used in the manufacture of plastics and synthetic rubber used as an insulating agent used in the manufacture of styrenated polyester, rubber-modified polystyrene, and copolymer resins used as a monomer for straight polystyrene chemical intermediate for styrenated phenols and styrene oxide used as a synthetic flavoring substance, e.g. for ice cream and candy also used to make paints.. 

Ludopal-Butyl Acrylate Formulation. The Ludopal U150 resin is recommended for wood varnishes. It forms films with elasticity and surface hardness. It contains 34% styrene the butyl acrylate-styrene-polyester ratio is 20 27 53, and the formulation viscosity is 150 mPa s at 25 °C.

The thermal properties of polyesters are of the greatest importance for their end applications. The important features of a polymer, such as bond strength, inter-and intra-molecular forces, resonance stability, crystallinity, structural imperfections and molecular weight, are responsible for their thermal behaviour. Long oil polyester resin and styrenated polyester resin are made flame retardant by the incorporation of bis-pyridine, bis-tribromophenoxo copper complex and polydibromophenylene oxide. 

Casting syrup (casting resin) n. Liquid monomers or partially polymerized polymers, usually containing catalysts or curing agents, capable of polymerizing to the solid state after they have been cast in molds. The materials most generally used as the acrylics, styrenes, polyesters, epoxies, silicones, and nylons.

Conventional SMC is prepared from unsaturated polyester resin and styrene, together with magnesium or calcium oxides or hydroxides. The bases serve to thicken the styrene-polyester solution, probably through ionomer formation.Usually, SMC is used together with fillers such as calcium carbonate and glass fiber reinforcement for high modulus.
