7. Technical Options Under Trial in Some Countries Note: These alternatives are not yet technically proven and their environmental benignness and economical viability is yet to be established.
28. SITUATION AFTER CFC PHASE OUT CFC Phase out was started in 90âs, change over decision by Indian Foam Industries was relatively simple, as selection had to be made from three alternative blowing agents which were well established in developed country and could easily be adopted by Indian Foam Sector. These were:- 14
34. Integral skinIt is the Rigids, Integral skin & some flexible slab stock foam applications where HCFCâs are being used. In this sector phase out program requires a careful approach 17
35.
36. Partial production can be changed to alternate blowing agent where HCFC 141b can be phased out stepwise over a period of time.
37. Use reduced HCFC 141b systems where mixture of HCFC 141b with other alternate blowing agents may be used, which can allow cut down of HCFC 141b phase wise and this solution can be adopted for SMEs.The right approach for phase out of HCFC 141b from Indian foam sector can be as above
38.
39. Energy should be most important factor particularly for rigid foams which are mainly used for insulation applications. 19 Safety and Energy Concerns

41. Another barrier that HCFC using enterprises possesses manufacturing equipments that are far from the end of product life.
