A polyurethane composition reaction mixture including: (a) at least one organic isocyanate; and (b) at least one butylene oxide-based hydrophobic polyol; a process for making the above polyurethane composition; a polyurethane composite article composition, a process for making the above polyurethane composite article composition; and a process for making a composite article from the above polyurethane composite article composition.

Polyol composition

A reaction system, such as for forming a rigid polyurethane foam, includes a flame retardant polyol that is a brominated reaction product of a cardanol component, a bromine component, and an additive component. The cardanol component includes at least 80 wt % of cardanol, based on the total weight of the cardanol component, and the bromine component including at least 80 wt % of bromine, based on the total weight of the bromine component.

Flame retardant polyol

A surfactant and a method of forming the surfactant having the formula (I) where a is an integer from 1 to 10, b is an integer from 0 to 10, Ris &#x2014;CHor &#x2014;H, n is an integer from 0 to 20, and Ris a moiety selected from the group consisting of (II), (III), (IV), (V), (VI), (VII) or (VIII) where m is an integer from 0 to 4. The surfactant can be used in a method for preparing a rigid polyurethane foam. 

Surfactants for polyurethane foams

A cardanol modified epoxy polyol may be used for forming a polyurethane resin system for use in applications such as coatings and composites formed by filament winding. The polyurethane resin system includes an isocyanate-reactive component that has a first cardanol component and the cardanol-modified epoxy polyol, and includes an isocyanate component that includes at least one polyisocyanate. The cardanol-modified epoxy polyol is a reaction product of an epoxy component and an epoxy-reactive component at a ratio of epoxy groups to epoxy reactive groups from 1:0.95 to 1:5, and the epoxy-reactive component includes a second cardanol component.

Cardanol modified epoxy polyol

This invention relates to rigid isocyanate-based polymer foam and composites thereof comprising a carbon black component comprising at least 50 weight percent of a fluorinated carbon black. Said foam having improved thermal properties, specifically, rigid polyurethane and/or polyisocyanurate foams for use in said insulation applications.
