WebThe highly filled Lupranol 4002/1 and Lupranol 4003/1 are based on KOH technology and so can be used for the production of HR and HLB foams. The products in the non-reactive polymer polyol series Lupranol 4005/1/SC are blends of Lupranol 4002/1 with Lupranol 2072 (KOH polyol) and so are compatible with standard HR polyols and can be used for ... WebSupel™ Swift HLB SPE is a proprietary and patent pending copolymer having both hydrophilic and lipophilic functional groups. It is for use as a sorbent material in solid phase extractions (SPE) before instrumental analyses.

Efficient foam booster … WebHydrophilic-lipophilic balance. The hydrophilic–lipophilic balance ( HLB) of a surfactant is a measure of its degree of hydrophilicity or lipophilicity, determined by calculating percentages of molecular weights for the hydrophilic and lipohilic portions of the surfactant molecule, as described by Griffin in 1949 [1] [2] and 1954.
