Yusuf Products is a manufacturing Gas Mantles that are used in high pressure lamps and lanterns for lighting where conventional electricity is not available. Yusuf Products is aslo into chemicals making calcium chloride & PCM. Phase Change Material is used in cell site shelters to maintain temperature.But what if you require this heat at a temperature other than zero Phase Change Materials or PCMs can give out latent heat at a wide range of temperatures from sub-zero to several hundred degrees. This heat-on-demand requirement is satisfied by PCMs which work at specified temperatures. We have developed a wide range of PCMs for different applications and our team of scientists and engineers can arrive at a customized PCM solution for your unique PCM problem.
