Liquid Polyurethane Foam  is consist of Polyol (Part-A ) and Isocyanate (Part-B).  Mixing   Part A with Part  B at ambient temperature expands to form a light density, hard, rigid,losed cell foam. PUF is available in a wide range of density (10- 450 Kg./ m3). The foam prepared from PUF not only have the best thermal properties but, it is the most versatile and fulfils the performance you need. lt is highly effective in maintaining the thermal integrity of cold storage utility and maintains the temperature of the system.
