K.K. Nag was founded in 1965 by the late Mr. Kalyan Kumar Nag, on a foundation of innovation and continuous improvement. We have a rich history of product and process innovation and pioneering new plastic processes. 

Prior to starting the Company, Mr Nag and his senior Partner, Mr R.A. Cole, pioneered the use of Expanded Polystyrene (EPS) in India (in fact, the generic name for EPS in India, "Thermocole", is derived from the words "Thermo" for heat and "Cole" for Mr R.A. Cole!). Interestingly, the two pioneers synthesised expandable polystyrene for the first time in India, in Mr. Cole's kitchen in Mumbai!

We pioneered the use of Fibreglass Reinforced Plastic (or FRP) in India. We are amongst the largest and most competent EPS processors in India. We are also involved with the production of Rotational Moulded, Injection Moulded and Blow Moulded plastics. 

We currently pioneer the use of Expanded Polypropylene (EPP) in India. We have an in-house team of design engineers and are constantly developing new designs. We have factories in Pune, Bengaluru and Puducherry and a centralised Tool Room in Pune. 

We are also India distributors for the Breezair range of Ducted Evaporative Air Coolers, an efficient alternative to compressed airconditioning. Breezair is manufactured by Seeley International Pty. Ltd., Australia.
