Rubber is a natural polymer of isoprene (polyisoprene), and an elastomer (a stretchy polymer). Polymers are simply chains of molecules that can be linked together. Rubber is one of the few naturally occurring polymers and prized for its high stretch ratio, resilience, and water-proof properties.
Synthetic rubber. A synthetic rubber is an artificial elastomer. They are polymers synthesized from petroleum byproducts. About 32 million metric tons of rubbers are produced annually in the United States, and of that amount two thirds are synthetic. Synthetic rubber, just like natural rubber, has many uses in the automotive industry for tires ...
Vulcanization. Worker placing a tire in a mold before vulcanization. Vulcanization (British English: Vulcanisation) is a range of processes for hardening rubbers. [ 1] The term originally referred exclusively to the treatment of natural rubber with sulfur, which remains the most common practice. It has also grown to include the hardening of ...
vulcanize rubber discovered in 1839, process perfected and patented in 1844. Signature. Charles Goodyear (December 29, 1800 – July 1, 1860) was an American self-taught chemist [ 1][ 2] and manufacturing engineer who developed vulcanized rubber, for which he received patent number 3633 from the United States Patent Office on June 15, 1844.
Rubber technology. Rubber Technology is the subject dealing with the transformation of rubbers or elastomers into useful products, such as automobile tires, rubber mats and, exercise rubber stretching bands. The materials includes latex, natural rubber, synthetic rubber and other polymeric materials, such as thermoplastic elastomers.
EPDM rubber. EPDM rubber ( ethylene propylene diene monomer rubber) [ 1][ 2][ 3] is a type of synthetic rubber that is used in many applications. EPDM is an M-Class rubber under ASTM standard D-1418; the M class comprises elastomers with a saturated polyethylene chain (the M deriving from the more correct term polymethylene).
Silicone rubber. An uncured piece of liquid silicone rubber. Silicone rubber is an elastomer (rubber-like material) composed of silicone —itself a polymer —containing silicon together with carbon, hydrogen, and oxygen. Silicone rubbers are widely used in industry, and there are multiple formulations. Silicone rubbers are often one- or two ...
Sulfur vulcanization is a chemical process for converting natural rubber or related polymers into materials of varying hardness, elasticity, and mechanical durability by heating them with sulfur [1] or sulfur-containing compounds. [2] Sulfur forms cross-linking bridges between sections of polymer chains which affects the mechanical and ...
