what is elastomer?what is resin?

Answer 1

"resin" is a generic name for plastic

usually, but not always, it refers to the plastic in its raw, powder form

elastomer is a technical term for a large group of polymers

he term elastomer is often used interchangeably with the term rubber, and is preferred when referring to vulcanisates. Elastomer comes from two terms, elastic (describing the ability of a material to return to its original shape when a load is removed) and mer (from polymer, in which poly means many and mer means parts). Each link of the chain is the "-mer" or basic unit that is usually made of carbon, hydrogen, oxygen and/or silicon. To make the chain, many links or "-mers" are hooked or polymerized together. They are amorphous polymers existing above their glass transition temperature, so that considerable segmental motion is possible. At ambient temperatures rubbers are thus relatively soft (E~3MPa) and deformable. Their primary uses are for seals, adhesives and molded flexible parts.

Elastomers are usually thermosets (requiring vulcanization) but may also be thermoplastic (see thermoplastic elastomer). The long polymer chains cross-link during curing and account for the flexible nature of the material. The molecular structure of elastomers can be imagined as a 'spaghetti and meatball' structure, with the meatballs signifying cross-links.

Answer 2

Resin is a raw material that can be molded to make various products such as energy absorbers (bumper systems). It's in the plastics industry. Check out www.jsp.com for more information.

Answer 3

An elastomer is a polymer with elastic (stretchy) properties.
