Polymer resins

 Polymer resins are a type of polymer, which is a large molecule made up of smaller units called monomers that link together in a chain-like structure. The structure of a polymer can be linear, branched, or a network. 

Here are some details about polymer resins:

Types

There are two main types of resin: thermoplastic and thermosetting. Thermoplastic resins can be repeatedly heated and cooled without damaging their properties. 

Structure

Polymer structures can be classified as homochain or heterochain. Homochain polymers contain only carbon atoms in the main chain, while heterochain polymers may have other atoms. 

Examples

Examples of polymers include proteins, cellulose, nucleic acids, concrete, glass, paper, plastics, and rubbers. 

Uses

Polymer resins are used in many products, including cars, construction, packaging, cosmetics, textiles, and more. 

Curing

To create a solid resin, a catalyst or hardening agent is added to trigger a chemical reaction that causes the monomers to bond together. This process is called curing or hardening.
