What is an example of an elastomer?
Examples of elastomers include natural rubbers, styrene-butadiene block copolymers, polyisoprene, polybutadiene, ethylene propylene rubber, ethylene propylene diene rubber, silicone elastomers, fluoroelastomers, polyurethane elastomers, and nitrile rubbers.
What makes something an elastomer?
elastomer, any rubbery material composed of long chainlike molecules, or polymers, that are capable of recovering their original shape after being stretched to great extents—hence the name elastomer, from “elastic polymer.” Under normal conditions the long molecules making up an elastomeric material are irregularly …
Which elastomer is the example of polymer?
Typical examples are polyisoprene, polybutadiene, and polychloroprene. Nondiene elastomers include, butyl rubber (polyisobutylene), polysiloxanes (silicone rubber), polyurethane (spandex), and fluoro-elastomers.
What are uses of elastomers?
Elastomer are used for rubber tires and tubes for vehicles, motorcycles, bicycles and recreational vehicles, lawn mowers and other yard work vehicles, belts, hoses, gloves, matting, toy balloons, rubber bands, adhesives and pencil erasers.
What are elastomers Write 2 examples?
Polyacrylic rubber and silicone rubber are examples of saturated elastomers. Butyl rubber and natural polyisoprene are examples of unsaturated elastomers.
Is pet an elastomer?
Poly(ethylene terephthalate) (PET) is a low cost, high performance thermoplastics. High-impact strength PET was prepared using polyethylene-octene elastomer (POE) grafted with a toughener, maleic anhydride.
What are elastomers give different examples and their uses?
Following are the examples of elastomers with their applications:
- Natural rubber: These are used in the automotive industry and in the manufacture of medical tubes, balloons, adhesives.
- Polyurethanes: These are used in the textile industry for manufacturing elastic clothing like lycra.
Is silicone A elastomer?
A part from Latex (the natural product), most elastomeric products fall into the category of “Synthetic Elastomer” the use of the word elastomer is used interchangeably with rubber nevertheless, Silicone is more correctly an “elastomer”.
Is Polystyrene an elastomer?
Polystyrene is a vinyl polymer. Structurally, it is a long hydrocarbon chain, with a phenyl group attached to every other carbon atom. Polystyrene is also a component of a type of hard rubber called poly(styrene-butadiene-styrene), or SBS rubber. SBS rubber is a thermoplastic elastomer.
What are elastomers give examples Class 11?
The materials for which strain produced is much larger than the stress applied, with in the limit of elasticity are called elastomers, e.g., rubber, the elastic tissue of aorta, the large vessel carrying blood from heart. etc. Elastomers have no plastic range.
What are the examples of polyethylene terephthalate?
Examples: Soda and water bottles; mouthwash bottles; peanut butter containers; salad dressing and vegetable oil containers; etc. Recycling: Plastic containers with a recycling symbol are collected in your blue recycling container.
How PET is manufactured?
Polyethylene Terephthalate (PET) is basically produced by polymerization of ethylene glycol and terephthalic acid. To be more specific, when the two raw materials of PET- ethylene glycol and terephthalic acid are combined with low vacuum pressure and high temperatures long chains of the polymer are formed.
