“Gist”: Viscoelastic foams produced by dispersing (silicon?) gel particles into the polyol stream.

Why it is interesting: Viscoelastic or “memory foams” are popular in the bedding industry. This case claims to improve upon the current technology by incorporating into the foam matrix 5 to 20% of ‘gel particles’ with a size of 1 to 5mm.  Advantages over curent memory foams mentioned are a lower glass transition temperature and a cool or “fresh” feel to the touch.  The ‘polymeric gels’ are however ill defined in the text and according to claim 6 “said silicone gel is a SEBS rubber”(?).  While being an interesting idea the case has little chance of being granted according to the examiners report.
