What are the applications of rubber?
Uses of RubberRubber moulded products are widely used industrially (and in some household applications) in the form of rubber goods and appliances.Rubber is used in garden hoses and pipes for small scale gardening applications.Most of the tyres and tubes used in automobiles are made up of rubber.More items….
What are disadvantages of synthetic rubber?
Though synthetic rubber has innumerable advantages but it’s disadvantages are no less. ◼It has poor mechanical properties . ◼Its tensile strength is quite weak. ◼Tear strength is also very poor.
What are the two types of rubber?
Different Types of Rubber There are basically two broad categories into which the rubber types can be placed. These are- Natural Rubber and Synthetic Rubber. Sometimes vulcanized rubber is also taken to be a type of rubber.
Is natural rubber a plastic?
Although both are polymers, plastic and rubber differ because: 1. Rubber can be considered elastomers, and that’s why when compared to plastics, they are naturally more elastic. … Synthetic rubber is derived from crude oil, whereas synthetic plastic is made of petroleum and natural gas.
What is the function of natural rubber?
Natural rubber is one of the most important polymers for human society. Natural rubber is an essential raw material used in the creation of more than 40,000 products. It is used in medical devices, surgical gloves, aircraft and car tires, pacifiers, clothes, toys, etc.
Is natural rubber toxic?
Natural rubber wins over plastics with many positive attributes. It is entirely nontoxic and free of petroleum or heavy metals. The material is a renewable resource and is biodegradable. Furthermore, natural rubber does not leach any worrisome byproducts, which has been a major issue with plastics.
What is butyl rubber used for?
Polyisobutylene and butyl rubber are used in the manufacture of adhesives, agricultural chemicals, fiber optic compounds, ball bladders, O-rings, caulks and sealants, cling film, electrical fluids, lubricants (2 stroke engine oil), paper and pulp, personal care products, pigment concentrates, for rubber and polymer …
What is rubber and its type?
Rubber is a natural polymer of Isoprene (2-Methyl -1, 3 – Butadiene). It is a linear, 1, 4 – addition polymer of Isoprene. Natural rubber has elastic properties and it undergoes long range reversible extension even if relatively small force is applied to it. Therefore, it is also known as Elastomer.
What are the advantages of natural rubber?
ADVANTAGES: NATURAL RUBBER exhibits high resilience, good tensile strength, and tear resistance. In addition to excellent wear resistance, NATURAL RUBBER also offers low permanent set characteristics plus good flexing qualities at low temperatures.
What is rubber and its properties?
It has excellent tensile, elongation, tear resistance and resilience. It has good abrasion resistance and excellent low temperature flexibility. Without special additives, it has poor resistance to ozone, oxygen, sunlight and heat. It has poor resistance to solvents and petroleum products.
What are disadvantages of natural rubber?
Get damaged under the action of strong acid, ozone, oils, greases and fats. Not recommended for use in alcohols, esters, or among the aromatic solution. Low temperature properties. Higher raw material prices. Does not apply to hot water being. Cannot be used in power transmission systems.
What do you mean by natural rubber?
Definitions of natural rubber. noun. an elastic material obtained from the latex sap of trees (especially trees of the genera Hevea and Ficus) that can be vulcanized and finished into a variety of products.

What is special about rubber?
Rubber can stretch and shrink. Rubber can contain gases. Rubber can fetch off lightning And/or electricity.
Why natural rubber is elastic in nature?
Natural rubber is made from a runny, milky white liquid called latex that oozes from certain plants when you cut into them. … These chains of molecules can be pulled apart and untangled fairly easily, but they spring straight back together if you release them—and that’s what makes rubber elastic.
Which rubber has properties of natural rubber?
Types of polyisoprene that are used as natural rubbers are classified as elastomers. Currently, rubber is harvested mainly in the form of the latex from the rubber tree (Hevea brasiliensis) or others.
What is natural rubber formula?
Natural rubber consists almost entirely of the cis-1,4 structure and hence is, chemically, cis-1,4 polyisoprene. When the chain units in a polymer consists of the same isomer it is said to be stereoregular.
How is natural rubber processed?
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 are the properties of rubber gloves?
Rubber gloves can be unsupported (rubber only) or supported (rubber coating of textile glove). Its primary purpose is protection of the hands while performing tasks involving chemicals. Rubber gloves can be worn during dishwashing to protect the hands from detergent and allow the use of hotter water.
How is rubber made and how is it useful?
Natural rubber is made by extracting a liquid sap, called latex, from certain types of tree. … Latex is gathered from the trees by making a cut in the bark and collecting the runny sap in cups. This process is called tapping. In order to prevent the sap from solidifying, ammonia is added.
What are the examples of natural rubber?
10 common types of rubberNatural Rubber (NR) Natural rubber (Isoprene) is derived from the latex sap of the Pará rubber tree (hevea brasiliensis). … Styrene-butadiene rubber (SBR) … Butyl (IIR) … Nitrile (NBR) … Neoprene® (CR) … Ethylene Propylene Diene Monomer (EPDM) … Silicone (Q) … Viton® (FKM)More items…•Jan 27, 2020
