Styrene-Butadiene (SBR) Rubber: Uses, Structure & Material
Styrene Butadiene Rubber Vs Natural Rubber While most of the properties of SBR are comparable with NR, but in some respects like heat build-up, tack and gum tensile strength make it inferior to natural rubber. Other disadvantages include: Low elongation at break; Low hot tear strength; Hysteresis, resilience

SBR - Styrene Butadiene Rubber Properties. Styrene butadiene rubber (SBR) is one of the cheaper synthetic general purpose elastomers that is sometimes used as a substitute for natural rubber (NR). It can be produced by free-radical solution polymerization or by emulsion polymerization either warm at 30 to 60°C (hot rubber) or cold at temperatures near 0°C (cold rubber). Emulsion SBR (ESBR) continues to lose ground to solution SBR (SSBR) which is better suited for high-performance tires.

Styrene-butadiene
The styrene/butadiene ratio influences the properties of the polymer: with high styrene content, the rubbers are harder and less rubbery. SBR is not to be confused with a thermoplastic elastomer made from the same monomers, styrene-butadiene block copolymer .

Styrene-butadiene rubber (SBR), a general-purpose synthetic rubber, produced from a copolymer of styrene and butadiene. Exceeding all other synthetic rubbers in consumption, SBR is used in great quantities in automobile and truck tires, generally as an abrasion-resistant replacement for natural rubber (produced from polyisoprene).

Butadiene Rubber - an overview | ScienceDirect Topics
Thermoplastic elastomers, based on blends of polyolefins with diene rubbers, such as butadiene rubber, natural rubber (NR), NBR, and SBR, have fairly good initial tensile properties, and their thermal stability is somewhat better than that of standard thermoset rubber materials [16,30,31].

Natural rubber/styrene-butadiene rubber blends prepared by
Blends of natural rubber (NR) and styrene-butadiene rubber (SBR) were prepared by solution mixing and vulcanized with sulfur and accelerator in a Semi-EV system at 433 K and 443 K in order to study the vulcanization kinetic and the influence of vulcanization temperature on final structure of the blends.

The Difference between Styrene-Butadiene Rubber
Styrene-Butadiene Latex is the most common type of styrene-butadiene emulsion polymer and it’s also important to note that it’s not just different from Styrene-Butadiene Rubber, it’s also different from natural latex. Natural latex is a white sap that comes from hevea brasiliensis trees, which are more commonly called rubber trees. This sap can be refined and compounded, and this makes it readily processed and optimizes its physical properties.

Polybutadiene
Polybutadiene is a synthetic rubber. Polybutadiene rubber is a polymer formed from the polymerization of the monomer 1,3-butadiene. Polybutadiene has a high resistance to wear and is used especially in the manufacture of tires, which consumes about 70% of the production. Another 25% is used as an additive to improve the toughness of plastics such as polystyrene and acrylonitrile butadiene styrene. Polybutadiene rubber accounted for about a quarter of total global consumption of synthetic rubbers

Difference Between Natural Rubber and Synthetic Rubber
Main Difference – Natural Rubber vs Synthetic Rubber. Natural and synthetic rubbers are two types of polymers with excellent properties that are widely in many industrial and household applications. Each rubber type has its own chemical and physical properties depending on the nature of the monomer and chemical structure of the rubber.
