Rubber Rubber is the name of a material which can stretch and shrink. It is a polymer. It can be either produced from natural sources (eg. natural rubber) or can be synthesised on a industrial scale. Lots of things are made from rubber, like gloves, tires, plugs, and masks and a few things can be made only from rubber. Natural rubber (latex rubber) is made from the white sap of some trees. There is a lot of it in the Hevea brasiliensis (Euphorbiaceae). Nowadays, synthetic rubber is made by a chemical process.

Difference Between Rubber and Plastic Synthetic means that the rubber is made from crude oil, which also happens to be another nonrenewable resource. Nevertheless, the other type (natural rubber) can be harnessed from trees (i.e. rubber tree), in which a substance (latex) is then extracted. 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. 2. Synthetic rubber is derived from crude oil, whereas synthetic plastic is made of petroleum and natural gas.

- Latex-pros and cons. Latex rubber is made from a milky liquid (not the sap) that comes from a rubber tree. This form of latex is called NR which stands for Natural Rubber. It can also be made synthetically from a chemical called SBR (Styrene Butadiene).

butyl rubber synthetic rubber: see rubberrubber, any solid substance that upon vulcanization becomes elastic; the term includes natural rubber (caoutchouc) and synthetic rubber. The term elastomer is sometimes used to designate synthetic rubber only and is sometimes extended to include caoutchouc as well.

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.eroxide curing is widely used for curing silicone rubber. The curing process leaves behind byproducts, which can be an issue in food contact and medical applications. However, these products are usually treated in a postcure oven which greatly reduces the peroxide breakdown product content.

- 1 Introduction. The substances known as rubber|natural rubber, gutta-percha, and various synthetic. compounds|are amorphous solids composed of long polymers.1 They vary somewhat. in chemical composition, melting point, and so on; however, they have the same elastic. properties, and for our purposes the distinctions between various kinds of rubber.

- Natural rubber is made from the milky sap of plants. Many species of plant have sap that contains rubber, but the vast majority of commercially produced rubber comes from the rubber tree, a tropical tree native to the Amazon Basin in South America. Its scientific name is Hevea brasiliensis, and it belongs to the spurge family (Euphorbiaceae).

Silicone It is made by curing or vulcanizing natural rubber. Silicon is injected into the long hydrocarbon chains of natural rubber under high heat and pressure. The result is silicone rubber. Silicone rubber is a silicon polymer with rubberized qualities. It was first produced under the chemical name of polydimethlysiloxane.Silicone rubber is heat resistant so can be used to make cookware including oven mitts, tongs, pot holders and pan handles.Silicone rubber also possesses non-stick qualities, so it can be formed into flexible cookware such as muffin and cake pans.ll silicone is inert, it does not react with other elements or compounds. There are (as yet) no known health hazards of silicone. Silicone is not biodegradable, but it can be recycled easily – where facilities exist. Silicone comes in two grades, food and medical grade silicone.

O-Ring Material Selection Guide Rubber refers to elastomeric compounds that consist of various monomer units forming polymers that are heat cured (vulcanized). Polymers are long molecular chains and are derived from the Greek poly (many) and meros (parts).

What are erasers made of? Currently voted the best answer. Typical erasers are made of rubber, but more expensive or specialized erasers can also contain vinyl, plastic, or gum-like materials.. http://en.wikipedia.org/wiki/Eraser. More and more of today's erasers are made from something other than rubber! While some of the pink erasers you find on pencils are made from synthetic rubber blended with pumice (a grit that enhances its ability to erase), an increasing number of erasers are made from vinyl. Vinyl is a type of durable, flexible plastic..

- Step 1: The rubber is formulated. Combining the latex (except in latex-free applications) plus other additives achieves specific qualities for the end compound. Compounds vary according to the desired properties for the rubber bands. Step 2: The rubber compound is processed through a machine called an extruder to form it into tube shape. It's very similar to the way that manicotti noodles or other hollow pastas are made...only the end result is a lot chewier!

How Rubber Works ­Rubber is a specific type of polymer called an elastomer: a large molecule that can be stretched to at least twice its original length and returned to its original shape. Early forms of rubber had many gluelike properties­, especially in hot weather. In cold temperatures, rubber became hard and brittle.

What is gum made up of? Up until WWII, chewing gum was made of a substance called chicle mixed with flavorings. Chicle is a latex sap that comes from the sapodilla tree (native to Central America).In other words, chicle is a form of rubber. Just like rubber bands don't dissolve when you chew them, neither does chicle.Chicle is a good bit softer than rubber bands and happens to soften more when it gets warm in your mouth.hicle is a latex sap that comes from the sapodilla tree (native to Central America).

- What is latex and Where does it come from? Latex is rubber and rubber is latex. Latex is a mixture of organic compounds produced by some plants in special cells called caticifers. The composition of latex differs from plant to plant. Most natural rubber comes from a single species of tree, Hevea brasiliensis. Though native to South America, H. brasiliensis is planted in large plantations in southeast Asia, including Malaysia.

Synthetic rubber The chemical synthesis of isoprene accelerated the reduced need for natural rubber, and the peacetime quantity of synthetic rubber exceeded the production of natural rubber by the early 1960s. Synthetic rubber is used a great deal in printing on textiles, in which case it is called rubber paste. In most cases titanium dioxide is used with copolymerization and volatile matter in producing such synthetic rubber for textile use. Moreover, this kind of preparation can be considered to be the pigment preparation based on titanium dioxide.

What Is A Polymer Polymers are both man made and are naturally occurring. For example, rubber is a natural polymeric material that is extremely useful and has been used by man for thousands of years. Rubber has excellent elastic properties, and this is a result of the molecular polymer chain created by mother nature.

- The fact that rubber can be made either soft or hard greatly increases the range of things we can use it for. Soft and stretchy latex is used in all kinds of everyday things, from pencil erasers, birthday balloons, and condoms to protective gloves, adhesives (such as sticky white PVA), and paints.

- More than 98 percent of natural crude rubber is a hydrocarbon polymer, a chainlike molecule consisting of many units linked together. The structures and chemistry of individual hydrocarbons depend in large part on the types of chemical bonds that link together the atoms of their constituent molecules. Nineteenth-century chemists classified hydrocarbons as either aliphatic or aromatic on the basis of their sources and properties.

- Natural rubber, also called India rubber or caoutchouc, as initially produced, consists of polymers of the organic compound isoprene, with minor impurities of other organic compounds plus water. Malaysia is one of the leading producers of rubber. Forms of polyisoprene that are used as natural rubbers are classified as elastomers. Natural rubber is used by many manufacturing companies for the production of rubber products. Currently, rubber is harvested mainly in the form of the latex from the para rubber tree or others. The latex is a sticky, milky colloid drawn off by making incisions into the bark and collecting the fluid in vessels in a process called tapping.
