The plant, representing a total investment of EUR 200 million, will have a capacity of 140,000 metric tons per year and will start up in the first half of 2015.

Apart from tires, performance butadiene rubbers are used for the modification of plastics in the manufacture of High-Impact Polystyrene (HIPS) for injection molding applications.
One of the most common occurrences of nitriles is in Nitrile rubber

While both rubbers help to increase fuel efficiency of a tire by reducing rolling resistance, S-SBR helps improves grip on wet roads, while Nd-PBR is highly resistant to abrasion thus making tires more durable.
“We are now moving from the age of tire design to the age of tire materials, which will make the difference in performance,” said Joachim Grub, Head of the LANXESS’ Performance Butadiene Rubbers (PBR) business unit.

The major use of butadiene rubber is in tires. Approx. 70 percent of the polymer produced goes into side walls and treads. PBD rubber is usually combined with other elastomers like natural rubber and SBR for tread applications. Other applications are golf ball cores, inner tubes of hoses for sandblasting, covers of hoses for pneumatic and water hoses, fuel for solid rocket boosters (in combination with oxidizers), and toughened plastics. About 25 percent of the total polybutadiene volume is used to improve the mechanical properties of plastics, in particular those of high-impact polystyrene (HIPS) and acrylonitrile butadiene styrene (ABS).

We introduce a chemically inspired, all-atom model of hydrogenated nitrile butadiene rubber (HNBR) and assess its performance by computing the mass density and glass-transition temperature as a function of cross-link density in the structure. Our HNBR structures are created by a procedure that mimics the real process used to produce HNBR, that is, saturation of the carbon–carbon double bonds in NBR, either by hydrogenation or by cross-linking. The atomic interactions are described by the all-atom “Optimized Potentials for Liquid Simulations” (OPLS-AA). In this paper, first, we assess the use of OPLS-AA in our models, especially using NBR bulk properties, and second, we evaluate the validity of the proposed model for HNBR by investigating mass density and glass transition as a function of the tunable cross-link density. Experimental densities are reproduced within 3% for both elastomers, and qualitatively correct trends in the glass-transition temperature as a function of monomer composition and cross-link density are obtained.
The major use of SBR is in the production of tires (ca. 75 percent). Car tires often contain up to 50 percent SBR. The styrene-butadiene ratio influences the properties of the tires: a higher styrene content improves the hardeness but makes them less rubbery. Other important applications are shoe soles and heels, hoses, adhesives, floor tiles, gaskets, and chewing gum.
SBR should not be confused with thermoplastic block-copolymers made from the same monomers, the so called styrene-butadiene block copolymers (SBS copolymers).
