Both rubber forms (natural and synthetic) are large molecular compounds. Normal rubber comes from a milky colloidal suspension, or latex, found in the sap of some plants. Synthetic rubber is manufactured out of natural monomers by polymerization or polycondensation. Because of manufacturing strategy rubbers are divided in to polymerizing and polycondensating this can affect the more use in the produce of specific products in their manufacturing capacity.

Major manufactured rubber forms: Isoprene, butadiene, butadiene-styrene and butadiene-methylstyrene, carboxylated, butadiene-methylvinylpyridine, butadiene-nitrile, chloroprene, ethylene-propylene, fluor rubbers and others. Original monomers for polymerization are diene hydrocarbons and ethylene derivatives. Major dienes are: isoprene and butadiene, chloropene, piperylene. Ethylene derivatives (isobutylene, acrylic p nitrile, styrene, methylstyrene) are found in synthesis by combined polymerization with diene hydrocarbons. Monomers synthesizing resources are natural gas, fat gas, ethanol, coal, limestone etc. Siloxane, urethane and other rubbers are made by polycondensation. Silicon natural ingredients, esters, dyisocyanates are found in this synthesizing method. Non-saturated rubbers are made by diene hydrocarbons polymerization or by their copolymerization with etylene derivatives. Different kinds have various framework, characterictics, vulcanization properties.

General-purpose are butadiene-styrene, butadiene and isoprene rubbers. General-purpose purposes are tires and the wide selection of technical rubber goods production. Specific rubbers are found in manufacturing of goods with specific houses (heat resistance, fat resistance, gas impermeability). These rubbers are polysulphide, butadiene-methylvinylpyridine, siloxane, butadiene-nitrile, chloroprene, ethylene-propylene and fluorine rubbers.

Vulcanization

Vulcanization identifies a specific recovering process of rubber involving high temperature and the supplement of curatives Rubber seal. It is really a substance method in which plastic molecules are linked to other plastic molecules by nuclear bridges. The combined vulcanization offer in a typical rubber substance comprises sulfur, along with accelerators, activators. Additives, anti-oxidants, plasticizing brokers are used to get required properties. Typical cure representative is sulfur. Plastic and sulfur blend is warmed-up to 130-160 Amount C. This process is referred to as a warm vulcanization. If rubber is vulcanized with sulfur chloride at the space heat, method is referred to as a cold vulcanization. Hot vulcanization is more wide-spread. Some rubber forms can be vulcanized without sulfur at 100 - 200 Amount C. For specific rubbers vulcanization peroxides, material oxides, polysulphides, isocyanides, diamines are utilized as recovering agents.
