Abstract
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.
Claims8
A composite comprising at least one substrate in contact with a rigid isocyanate-based polymer foam made from a reactive formulation comprising a mixture of:
- (A) an A-side comprising
- (i) an organic isocyanate,
- (B) a B-side comprising:
- (ii) an isocyanate-reactive component,
- (iii) a blowing agent,
- and
- (iv) one or more additional component selected from a catalyst, a nucleating agent, a surfactant, a crosslinker, a chain extender, a flame retardant, a filler, a colorant, a pigment, an antistatic agent, reinforcing fibers, an antioxidant, a preservative, an infrared blocking agent, or an acid scavenger,
- and
- (C) from 3 to 7 parts carbon black comprising
- (v) from 50 to 100 percent by weight of a fluorinated carbon black having a fluorine to carbon (F/C) molar ratio of at least 10/90, wherein parts by weight are based on the weight of the B-side component (B) and component (C) may be either wholly in the A-side (A), wholly in the B-side (B), or a portion in the A-side and a portion in the B-side.

A process for producing a composite comprising the steps of:
- (I) contacting at least one substrate with a mixture of a rigid isocyanate based polymer reactive formulation comprising:
- (A) an A-side comprising
- (i) an organic isocyanate,
- (B) a B-side comprising:
- (ii) an isocyanate-reactive component,
- (iii) a blowing agent,
- and
- (iv) one or more additional component selected from a catalyst, a nucleating agent, a surfactant, a crosslinker, a chain extender, a flame retardant, a filler, a colorant, a pigment, an antistatic agent, reinforcing fibers, an antioxidant, a preservative, an infrared blocking agent, or an acid scavenger,
- and
- (C) from 3 to 7 parts carbon black comprising
- (v) from 50 to 100 percent by weight of a fluorinated carbon black having a fluorine to carbon (F/C) molar ratio of at least 10/90, wherein parts by weight are based on the weight of the B-side component (B), and component (C) may be either wholly in the A-side (A), wholly in the B-side (B), or a portion in the A-side and a portion in the B-side,
- and
- (II) subjecting the resulting reactive formulation to conditions sufficient to cure the reactive formulation to form a rigid isocyanate-based polymer foam contacting at least one substrate forming a composite a rigid isocyanate-based polymer foam.
