T-501A is spray blend polyols, it reacts with Polymeric MDI ,PAPI to produce foam which has excellent performances, which are as follows,

  1) fine and uniformity cells
  2) low thermal conductivity
  3) perfect  resistance
  4) good low temperature dimentional stability.
It applies to all kinds of thermal insulation engineering which uses the spray technology, such as cold rooms, pots, large-scale pipelines and construction metope etc.
