PEL-FAC 9800 is compatible with high polyester polyol formulations and formulations with polyether polyol where it improves foam flowability, compressive strength and k-factors. When used at typical surfactant levels, it will enhance hydrocarbon solubility in pre-blended polyol systems containing other compatibilizing agents. PEL-FAC 9800 may be used at higher levels than typical surfactants to act as a hydrocarbon compatibilizing additive if needed. It is also compatible with commercially available silicone surfactants such as our PEL-SIL line of silicone copolymers. Some of the typical applications for PEL-FAC 9800 include foam core laminate and pour-in-place insulation.
