PU-108 is the two-part rigid foam system, When Part A on mixing with Part B at ambient temperature expands to form a light density, hard, rigid, closed cell foam. PUF is available in a wide range of Free Rise density (10- 400 Kg./m3) and pack core density ( 16-500 kg/m3). The foam prepared from PUF liquid 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.
