Products in Butadiene Rubbers (BR): Conveyor Parts

Synthetic cis-butadiene rubber BR-1243 Nd HV is a product of polymerization of butadiene in solution in the presence of rare-earth metal-base catalysts with addition of an antioxidant, which contains at least 97% of 1,4-cisbonds. The polymer contains no nitrosamines or substances that may be a source of nitrosamines.

Synthetic cis-butadiene rubber SIBUR BR-1203 Ti is the polymerization product of butadiene in solution; in the presence of titanium catalyst; 1,4-cis – at least 90%. The polymer is stabilized with non-staining antioxidant and contains no nitrosamines or substances that may be a source of nitrosamines.

Synthetic cis-butadiene rubber SIBUR BR-1245 is a product of polymerization of butadiene in solution in the presence of neodymium catalyst; 1,4-cis — at least 97%; polydispersity — no more 2.5. The polymer is stabilized by non- staining antioxidant and contains no nitrosamines or substances that may be a source of nitrosamines.

Synthetic cis-butadiene rubber SIBUR BR-1243 Nd Grade B (LP) is a product of polymerization of butadiene in solution in the presence of neodymium catalyst; 1,4-cis — at least 97%; polydispersity — no more 2.85. The polymer is stabilized by non- staining antioxidant and contains no nitrosamines or substances that may be a source of nitrosamines.

Synthetic cis-butadiene functionalized rubber SIBUR BR-1243 E-Pro is the polymerization product of butadiene in solution in the presence of neodymium catalyst; 1,4-cis at least 97%; polydispersity not more 2.6. The polymer is stabilized by non-staining antioxidant and contains no nitrosamines or substances that may be a source of nitrosamines. The product is characterized by improved processability.

Milagro Rubber Budene is the second largest volume synthetic rubber produced, next to styrene-butadiene rubber (SBR). High cis BR will usually have cis content >95% which gives rise to better “green strength” and increased cut growth resistance in the cured product.

KRAIBURG CR is a chloroprene rubber is used in applications such as conveyor belts, seals, hoses, air springs, roller coatings, wiper blades, linings, cable sheathings and rubber-coated fabrics.

Milagro Rubber Buna is the second largest volume synthetic rubber produced, next to styrene-butadiene rubber (SBR). High cis BR will usually have cis content >95% which gives rise to better “green strength” and increased cut growth resistance in the cured product.

JSR has developed this grade as the only supplier in the world. Applications are broad. For example, the vibration absorbing materials for automobile, films, tubes, rubber shoe soles, some injection molded products and plastic modifiers.

Polysciences, Inc. Poly(2-chloro-1,3-butadiene) is widely used rubber for applications requiring good solvent resistance.
