4. PLASTICIZERS & POLYMERS :-
Plasticizers are additives that soften the materials (usually a plastic or a concrete mix) they are added to. Although the same compounds are often used for both plastics and concretes, the desired effect is slightly different. Polymer is a term used to describe molecules consisting of structural units and a large number of repeating units connected by covalent chemical bonds. The term is derived from the Greek words: polys meaning many, and meros meaning pars. NNS Chemicals (Private) Limited. dealing with following types: |
