Title:
MECHANICALLY FROTHED GEL ELASTOMERS AND METHODS OF MAKING AND USING THEM
Document Type and Number:
WIPO Patent Application WO/2015/187950
Kind Code:
A3
Abstract:
A method of making frothed gel in which no blowing (gas producing) agents are used, and in which non-aqueous gel precursor polyol and additive systems are frothed using a froth mix head, either prior to, or after addition of the isocyonate, depending on desired speed of reaction and cell structure. Isocyanate may be added after the material leaves the froth mix head, in which case it can be added to the froth using a static mixer. No water, or very little water, is used in the process.
