Currently there are only two main blowing agents being used by polyurethane industry in most of the article 5 countries including India.
Pentane is highly flammable and needs fire safety measures in transportation, storage and during manufacturing process.

India has large number of small and medium size enterprises, quite often located in crowded areas. It is very important that an option selected should cater the need of SME sector.
HFCs can be used in combination with other blowing agents which can give good balance of foam Performance, cost and energy efficiency.

SMEs are the backbone of Indian economy.
The Polyurethane foam sector, SMEs consists of 91% of the total Foam Industry.
Presently available alternates are mainly HFCs, such as 245FA, 134 A, 365FA and Hydro Carbons(Pentanes)
Hydrocarbons are highly inflammable and it is not feasible to use them in pre blended Polyols which is widely used by SMEs
Indo-US Workshop on HFCs 18-02-2011
The Polyurethane Foam Industry is open for a Dialog with its counterpart US Industry to understand about the low GWP alternative if any, including their economical & Technical viability and the time frame for its availability.
