Abstract
Fluoropolymer-free isocyanate-reactive compositions that include a polyether polyol, particles dispersed in the polyether polyol, and water. The particles dispersed in the polyether polyol include polymeric particles, and polymer-ceramic composite particles. Polyurethane foams produced using such isocyanate-reactive compositions. Also described are targets that include a cover and a foam core enclosed by the cover. The foam core does not include any fluoropolymer and includes polymeric particles and polymer-ceramic particles.
Claims20
An isocyanate-reactive composition comprising:
- (a) a polyether polyol having a functionality of 2 to 8, an OH number of 20 to 400 mg KOH/g, and a (poly)oxyethylene content of 0 to 50% by weight, based on total weight of the polyether polyol (a);
- (b) particles dispersed in the polyether polyol, the particles comprising:
- (i) polymeric particles, and
- (ii) polymer-ceramic composite particles;
- and
- (c) water,
- with the proviso that the isocyanate-reactive composition does not include any fluoropolymer.
4 more elements
A target comprising:
- (a) a cover having target markings formed thereon;
- and
- (b) a foam core that is enclosed by the cover,
- wherein the foam core comprises:
- (i) polymeric particles;
- and
- (ii) polymer-ceramic composite particles, and
- with the proviso that the foam core does not include any fluoropolymer.
