摘要:
An amine softening additive is useful in softening all-water blown flexible polyurethane foam to achieve low IFD valves while retaining the other commercially necessary properties of the foam. The additives are tertiary amine polyisocyanate catalysts which contain at least one contiguous three carbon chain and should be added to the foam system at about 0.1 to 2.0 parts per hundred of polyol.
摘要:
A process for preparing hydrocarbon blown rigid polyurethane foam using a novel compatibilizing agent. The compatibilizing agent is an alkoxylate adduct of a triglyceride with a hydroxyl value of about 100 or less. The triglyceride adduct has an ethylene oxide content of at least 40% by weight thereof. These adducts may be used alone or in mixture with other compatibilizers. The compatibilizers increase the stability of rigid foam formulation emulsions containing greatly increased hydrocarbon blowing agent levels while showing little or no adverse affect to physical properties of foams prepared therewith.

This invention relates to hindered-hydroxyl functional (meth)acrylate compounds and derivatives thereof and to processes for the preparation thereof. The hindered-hydroxyl functional (meth)acrylate compounds and derivatives thereof are useful alone or in the production of intermediates, and have utility in coatings, adhesives, inks, sealants, reactive surfactants, wet adhesion monomers, as well as in other end uses.
摘要:
Silicone surfactants for use in inert gas blown polyurethane foams comprise low to moderate molecular weight comb-type flame-retardant silicone copolymers possessing no high ethylene oxide content branches. The silicone surfactants yield Dissolved Gas Technology foams having improved consistency as compared to other surfactant compositions.
