Low density microcellular polyurethane foams suitable for athletic shoe midsoles and other applications are prepared by diol chain extension of 12 to 16% free NCO isocyanate-terminated prepolymers prepared by reacting an excess of di- or polyisocyanate with one or more high molecular wei
6391935 Viscoelastic polyurethane foams May 21, 2002
Viscoelastic foams and a process for making them are disclosed. The foams are produced with a unique isocyanate-reactive mixture that includes a low equivalent weight polyol and from about 15 to about 70 wt. % of a polyester or polyoxyalkylene monol having a number average equivalent
6264775 Face-up coating of carpet backs with polyurethane July 24, 2001
Tufted carpeting can be manufactured employing polyurethane adhesives and cured face up without dripping, when one or more drip-reducing process steps of adding a non-Newtonian thickener to the adhesive or forming a viscosified or cured film on the outer surface of the adhesive are p
6218444 Dispersion polyols for hypersoft polyurethane foam April 17, 2001
Dispersion polyols which are liquid-liquid dispersions containing a first having a substantially Polyoxypropylene internal block having an equivalent weight in excess of about 700 Da and a high oxyethylene-content external block, and a second polyol which is a substantially polyoxyet
6211330 Process of making an epoxide polymer using highly active double metal cyanide catalysts April 3, 2001
Improved double metal cyanide (DMC) catalysts are disclosed. The catalysts comprise a DMC compound, an organic complexing agent, from about 0.1 to about 10 wt. % of an organophosphine oxide, and optionally, a polyether. Compared with other DMC catalysts prepared in the absence of the
6171678 Polyurethane carpet backings with improved tuft bind January 9, 2001
Improvements in tuft bind and/or elongation of tufted carpet may be achieved by selecting, as components of a tuft bind adhesive, one or more of: i) a polyol component comprising a low or ultra-low unsaturation polyoxypropylene polyol optionally containing up to 30 weight percent oxy
6143802 Process for the preparation of polyol polymer dispersions November 7, 2000
Polymer polyols and polymer-modified polyols having substantially no transition metal content in the polyol continuous phase may be prepared from encapsulative double metal cyanide complex-catalyzed polyoxyalkylene polyether base polyols without substantial removal of double metal cyanid
6127443 Energy management polyurethane rigid foams with high recovery October 3, 2000
Energy absorbing rigid polyurethane foams have both high energy absorbing efficiency as well as exceptional recovery after deformation, allowing their use in visible energy absorbing structures, particularly in the transportation vehicle industry. The foams are prepared by reaction of on
