Bound Rubber - an overview | ScienceDirect Topics
Bound rubber is a very specific measurement done on green mixes; it consists of determining the part of rubber that cannot be extracted by a good solvent (Dannenberg, 1986). A small part of rubber, previously weighted, is put in toluene and submitted to extraction at a room temperature.

Synthetic Rubber - an overview | ScienceDirect Topics
Synthetic rubber (cis-1,4-polyisoprene) can be obtained via radical chain polymerization of the monomer (isoprene). It was the isolation of this chemical during the pyrolysis of natural rubber that provided the key to identifying the building block. The evolution of the catalysts occurs for 70 years when Ziegler-type catalyst was used (1955).

Rubber Formulation - an overview | ScienceDirect Topics
Peter G. Pape, in Handbook of Adhesives and Surface Preparation, 2011. 15.7.3.2 Wire and Cable Applications. Mineral-filled rubber formulations were developed for wire and cable applications in the 1960s where exceptional electrical resistance was needed to prevent electrical breakdown under high, humid- stress conditions. Carbon black is a conductive filler so the resulting rubber has poor ...

Butadiene Rubber - an overview | ScienceDirect Topics
In Handbook of Antiblocking, Release, and Slip Additives (Third Edition), 2014. 10.7 RESIDUES ON MOLDS. Interfacial layers were formed on the surfaces of molds used with nitrile butadiene rubber compounds. 33 These layers help to reduce adhesion to the mold and thus more easily remove the molded part. Stearic acid is the major component of this layer which was measured to be 6 nm thick on the ...

Nitrile Rubber - an overview | ScienceDirect Topics
Nitrile rubber, which is also called Buna-N or NBR, is an unsaturated synthetic copolymer. It is commonly used to make hoses, seals, gloves, and many other industrial products. The mechanical response of nitrile rubber can be tested in many different ways. The example shown here used uniaxial compression at different strain rates and strain cycles.

Synthetic Rubber - an overview | ScienceDirect Topics
The different types of synthetic rubber include neoprene, Buna rubbers, and butyl rubbers, and they are usually developed with specific properties for specialist applications. Styrene-butadiene rubber and butadiene rubber (both Buna rubbers) are commonly used for tire manufacture. Butyl rubber, since it is gas-impermeable, is usually used for inner tubes.

Silicone Rubber - an overview | ScienceDirect Topics
Silicone rubber is a semiorganic synthetic. Its structure consists of a chain of silicon and oxygen atoms rather than carbon and hydrogen atoms, as in the case with other types of rubber. The molecular structure of silicone rubber results in a very flexible—but weak—chain. Silicones are very stable at low and high temperatures.
