Flexible Polyurethane Foams for Thinner Car Seats

Gist”: Use of 1,5-pentanediol in flexible foam formulations results in foams with correct comfort properties to allow for thinner car seats.

Why it is interesting: About 2 pphp of 1,5 pentanediol is used together with a  mixture of MDI monomers and a  conventional flexible foam formulation to produce a 55kg/m3 foam with supposedly the correct comfort properties (hardness, hystersis loss, vibration damping  etc.) for a thinner car seat.  While the use of chain extenders is rare in flexible foams, it may very well make sense in somewhat higher-density systems. The first claim of this application however covers much more than flexible foam and will most probably not get granted as such.
