Polymers and Resins

Polymers and resins comprise of the foundation of the chemicals industry. Both natural and synthetic resins comprise non-crystalline and viscous liquids. On the other hands polymers are made of repeating structural units, which is derived from a specific compound called monomer, which is combined together by chemical bonds.

Natural resins are increasingly being replaced by synthetic resins due to their superior chemical and physical properties. Synthetic resins comprise of a large class of synthetic products that possess properties quite similar to their natural counterparts such as rapid hardening. However, in terms of chemical properties, both resins are entirely different. Acetal, amino, acrylic, epoxy and polyesters among others are some of the major forms of synthetic resins. Resins find wide application in industries such as paints and coatings, plastics, adhesives, inks and various others.

Polymers are compounds with a high molecular weight possessing similar elements combined in a similar proportion through polymerization. Polymers can be either bio-based or synthetic based, which depends upon the source of origin and method of production. Synthetic polymers such as polyethylene (PE), polypropylene (PP), polystryrene (PS), and polyvinyl chloride (PVC) are usually sourced from fossil fuels such as natural gas and crude oil among others, and are produced by chemical processes. Polymers find wide application in industries such as automotive, agriculture, construction, packaging, healthcare and electronics among others. Bioploymers comprise of repetitive monomeric units which are sourced from living organisms and are obtained by chemical enhancements of natural polymers. Bio polymers such as bio polyethylene terephthalate (bio-PET), bio polyethylene (bio-PE) and polylactic acid (PLA) have the potential to be converted into plastics and their growth seems to be promising.
