What is Rubber?
Rubber is a polymer made from plants and is categorized as such. a chemical complex made up of several smaller molecules of the same type and big molecules. While some polymers are created in factories and research facilities, others are found in nature. A polymer is a chemical substance made up of several identically sized smaller molecules. While some polymers are created in factories and research facilities, others are found in nature. One of the most vital polymers for human civilization is rubber. More than 40,000 goods are made with rubber, which is a crucial basic resource.
How is Rubber made?
To transform rubber into a product that can be used, both natural and synthetic rubber must go through a number of processes. The ultimate product's intended usage will determine how these stages are modified. First, chemicals are used to stabilize the rubber. Without it, rubber would become brittle in cold weather and sticky in hot weather. The rubber mixture frequently contains a carbon black filler to increase strength and durability.
After carefully mixing the rubber, it is allowed to cool before being moulded. It can be extruded into hollow tubes or molded by being forced through perforations in rollers, a process termed as calendaring.
To finish, rubber goes through a vulcanization heat-treatment process to make it strong and resilient. The rubber is heated in this procedure to strengthen the linkages or cross-links between the rubber molecules and stop them from fast disintegrating (typically with sulphur). Charles Goodyear accidentally discovered this technique when he dropped some rubber onto a hot fire and noticed how the heat made the rubber stiffer and more resilient.
The rubber is vulcanized to eradicate any defects before being molded into the completed product. One of the most important innovations ever made, rubber is currently utilized in many different ways.
As mentioned above, there are so many products made using rubber. A few of them are listed below-

Types of Rubber
Natural rubber is derived from latex, a milky liquid that can be found in latex vessels (ducts) or in the cells of plants that make rubber. Of the roughly 20,000 plant species that produce latex, only 2,500 have been found to contain rubber.
The latex that drips from the bark of various tropical and subtropical trees is used to make natural rubber. Milky white liquid called latex has some solid particles suspended in it. It's used in a variety of products, including toys, apparel, medical equipment, surgical gloves, vehicle and airplane tires, pacifiers, and more.
Silicone is a polymer that contains silicon together with other elements including carbon, hydrogen, and oxygen. Silicone is what makes silicone rubber an elastomer, or rubber-like substance. There are several formulas of silicone rubbers, and they are widely employed in industry. One- or two-part polymers, silicone rubbers may add fillers to enhance characteristics or lower cost.
From 55 to 300 °C (70 to 570 °F), silicone rubber is typically non-reactive, stable, and resistant to harsh conditions without losing its useful qualities. Silicone rubber is used in a wide range of products because of these qualities as well as how simple it is to manufacture and shape. Some examples include voltage line insulators, automotive applications, cooking, baking, and food storage items, apparel such as undergarments, sportswear, and footwear, electronics, medical devices and implants, as well as a variety of apparel and footwear.
A synthetic rubber made from acrylonitrile (ACN) and butadiene, nitrile rubber is also referred to as nitrile butadiene rubber, NBR, Buna-N, and acrylonitrile butadiene rubber. Perbunan, Nipol, Krynac, and Europrene are all trade names. The resistance of this rubber to oil, fuel, and other chemicals makes it exceptional. Fuel and oil handling hoses, seals, grommets, and self-sealing fuel tanks are all made with NBR in the automotive and aerospace industries.
EPDM rubber is a type of synthetic rubber. Due to its exceptional toughness and flexibility, it is utilized in a variety of settings, including cold rooms, non-slip deck and playground coatings, autos (where it is used for cooling system hoses, window and door seals, and more), and many others. Simply said, pure rubber becomes brittle with temperature fluctuations, whereas synthetic rubber (EPDM) maintains suppleness and can withstand temperature variations for decades.
Butyl rubber, also known simply as "butyl," is a synthetic rubber made of an isoprene and butylene copolymer. Rubber made of isobutylene and isoprene is referred to as IIR. The homopolymer of isobutylene, or 2-methyl-1-propene, on which butyl rubber is based is polyisobutylene, also referred to as "PIB" or polyisobutene. By polymerizing around 98% isobutylene and 2% isoprene, butyl rubber is created. Polyisobutylene structurally mimics polypropylene, but has two methyl groups instead of one replaced on every other carbon atom. Colorless to pale yellow viscoelastic polyisobutylene is a substance. The majority of the time, it is tasteless and odourless, yet occasionally it will have a faint aroma.
Fluorosilicone, a type of silicone rubber, provides superior resistance to fuel, oil, and other chemicals while retaining great mechanical properties and high thermal stability. Some of these extra benefits are partially countered by the fact that fluorosilicone is around five times more expensive than silicone.
Families of synthetic rubbers made from styrene and butadiene are referred to as "styrene-butadiene rubber" (SBR) (the version developed by Goodyear is called Neolite). When protected by additives, these materials exhibit good abrasion resistance and good ageing stability. Over 5.4 million tonnes of SBR were processed globally in 2012. Various forms of SBR are used to manufacture about 50% of automotive tyres. The styrene/butadiene ratio affects the polymer's characteristics; rubbers with a high styrene concentration are harder and less bouncy. Despite coming from the same monomers, SBR should not be mistaken with the thermoplastic elastomer known as styrene-butadiene block copolymer.
