Polymer Chemistry Department
This department conducts demand driven, basic and applied research in Polymer Science and Technology. The department’s main concerns focus on value addition to Natural Rubber (NR) by the way of optimizing the properties of NR and NR based products. The department provides technological know-how to rubber wood processing and producing different types of adhesives. While providing consultancy services to the industry, the department also undertakes contract projects and provides specific testing services in its fields of expertise. The department has high tech instruments such as DMA, DSC, FTIR for cater to the people in the field of polymer Science. Areas of business that make use of these tests include the rubber, plastic, surface coating, bitumen, wood, tyre, glove and footwear industries.

- Development of environmentally friendly accelerator system for rubber compounds
- Development of environmental friendly preservative system for NR latex.
- Value addition of NR through in-situ reinforced NR /filler composites
Major analytical services and testing facilities
- Material (such as elastomers,plastics,polymer blends,additives, resins, adhesives etc.)identification and characterization using Fourier Transform Infrared Spectrophotometer(FTIR)
- Silicone oil extraction and analysis on glove /Yarn samples using FTIR
- Bloom analysis on rubber products.
- Determination of thermal characteristics such as glass transition temperature (Tg), melting point and crystallization temperatures, degree of crystalinity etc., of polymers using Differential Scanning Calorimeter (DSC).
- Evaluation of viscoelastic properties/ behaviours of polymers in terms of storage modulus, loss modulus and tan delta using Dynamic Mechanical Analyzer (DMA)
Other services offered by the Polymer Chemistry Department
- Develops new formulations for various products such as sealants, emulsions, membranes, surface coatings, adhesives etc.,upon the requests of clients/ industries.
- Provides supervision and laboratory facilitiesfor projects conducted by postgraduate and undergraduate students of state universities.
