What are the methods of processing rubber?

Rubber processing consists of four basic steps: (1) mastication, when the elastomer is sheared and the molecules are broken down to give easier flow, (2) mixing, usually carried out immediately after mastication, when additives are incorporated, (3) shaping of the viscous mass, for example, by extrusion or molding, and …

What is rubber processing?

Processing of rubber Methods for processing rubber include mastication and various operations like mixing, calendering, extrusion, all processes being essential to bring crude rubber into a state suitable for shaping the final product.

What is rubber Slideshare?

RUBBER •rubber is an elastic hydrocarbon polymer which is milky, emulsion in the sap of several varieties of plant. • produced from a milky liquid called LATEX. •It is also known as ELASTOMER. Rubber tree(extraction of milk) It can be classified in two parts: 1.natural rubber 2.synthetic rubber.

What is the purpose of rubber technology?

Rubber Technology is a specialized field of science that comprises of the study of transformation of rubbers or elastomers into useful products. It also focuses on the processing of natural rubber or synthetic rubber, processing of latex and so on.

How rubber is cultivated?

Rubber cultivation in plantation is a systematic agriculture in which first seeds have been raised in a nursery. When the rubber seedlings are about 5 cm in diameter buds from high yielding clones are grafted on to the seedlings. This grafted section forms the main part of the tree.

What properties does rubber have?

Some of the material’s key characteristics are high tear and tensile strength, resilience, and resistance to abrasion, friction, extreme temperatures, and water swell. Typical uses include adhesives, flooring and roofing, gloves, insulation, and tires.

How do you manufacture rubber?

The three primary methods of molding rubber are compression molding (used in making tires among other products), transfer molding and injection molding. Vulcanization of the rubber occurs during the molding process rather than as a separate step. Vulcanization completes the rubber-production process.

What is compounding of rubber?

Rubber compounding or formulation refers to the addition of certain chemicals to raw rubber in order to obtain the desired properties. Through formulation long-chain molecules are chemically linked together, forming networks and transforming the material from a viscous liquid to elastic solid.

What is rubber processing and shaping?

Rubber Processing and Shaping• Production of rubber goods consists of two basic steps: 1. Production of the rubber itself  Natural rubber is an agricultural crop  Synthetic rubbers are made from petroleum 2.
