Hello This is Ganesh from Chennai, India. We are into the field of production of polyol basic raw material for the production of polyurethane. We develop a large range of polyol with different properties as required by the end users. We do R & D in this field and find the effect of the polyol properties on the foam/polyurethane that we produce. I am very interested in your project. If you are interested , please do contact me. Thanks

Dear Sir or Madam, I gained experiences in ridged PU pouring processing and mixing process from the fridge manufacturer when I was working as a PU process engineer. There three substances in chemical preparing process ; Isocyanate, Plyol, and blowing agent(cyclopentane ) The mixing plant was designed as recirculation system which supplies the mixed-polyol and isocyanate to the vessel in processing area. The ratio of two chemical was controlled by metering system. In the generating PU, pour-head injects substances into the fridge under the high pressure condition then they will be mixed. PU foam expands over the time and it became a ridged foam after about 40 seconds. To maintain and improve foam physical and thermal properties are my main roles. Here are the foam quality indicators : -Density, K-factor, bubble in foam, foam mixing, cure time, I hope that my experience is able to contribute your project. Regards, Kasidit P.
