Abstract
Embodiments of the present disclosure are directed towards hybrid foam formulations that include: an isocyanate-reactive composition, and a high-functionality crosslinker; an azo type radical initiator; and an isocyanate.
Claims10
An isocyanate-reactive composition comprising:
- a polyol composition having an average hydroxyl functionality from 3.7 to 5.7 based upon total polyols of the polyol composition, an average hydroxyl number from 370 to 550 mg KOH/g based upon total polyols of the polyol composition, and a number average molecular weight from 400 to 750 g/mol based upon total polyols of the polyol composition;
- and
- a high-functionality crosslinker having an average functionality of 3.0 or more, wherein functional groups of the high-functionality crosslinker are selected from acrylate groups, allyl groups, OH groups, NH2 groups, COOH groups, and combinations thereof, wherein from 10 to 99 percent of the functional groups of the high-functionality crosslinker are acrylate groups, allyl groups, or combinations thereof.
A method of forming a foam product, the method comprising:
- combining:
- a polyol composition having an average hydroxyl functionality from 3.7 to 5.7 based upon total polyols of the polyol composition, an average hydroxyl number from 370 to 550 mg KOH/g based upon total polyols of the polyol composition, and a number average molecular weight from 400 to 750 g/mol based upon total polyols of the polyol composition;
- a high-functionality crosslinker having an average functionality of 3.0 or more, wherein functional groups of the high-functionality crosslinker are selected from acrylate groups, allyl groups, OH groups, NH2 groups, COOH groups, and combinations thereof, wherein from 10 to 99 percent of the functional groups of the high-functionality crosslinker are acrylate groups, allyl groups, or combinations thereof,
- an azo type radical initiator;
- and
- an isocyanate to form a hybrid foam formulation;
- and
- curing the hybrid foam formulation to form the foam product.
