Abstract
An article is provided that comprises fibers, as is a method of forming the article. The fibers comprise an organopolysiloxane component selected from (i) an organopolysiloxane having the formula (R3SiOi/2)w(R2Siθ2/2)x(RSiθ3/2)y(Siθ4/2)z (I), wherein each R is selected from the group of an inorganic group, an organic group, and combinations thereof, w is from 0 to 0.95, x is from 0 to 0.95, y is from 0 to 1, z is from 0 to 0.9, and w+x+y+z=1, and (ii) a cured product of said organopolysiloxane having the formula (I), and combinations of (i) and (ii), provided that the fibers are free from organic polymers, organic copolymers, and organosiloxane-organic copolymers. The method of forming the article includes the step of forming fibers from a composition. The composition used to form the fibers comprises the organopolysiloxane having the formula (I), provided that the composition is free from organic polymers, all-organic copolymers, and organosiloxane-organic copolymers. The article exhibits excellent hydrophobicity and maximized fire resistance.
