Title: COMPOSITE MEMORY FOAM AND USES THEREOF

 Number/Link: US2012316254

Applicant/Assignee: ZEDBED INTERNAT INC

Publication date: 13-12-2012

Gist”: Polyurethane memory foam containing polyurethane elastomer particles for improved thermal comfort.

Why it is interesting:  Soy-oil polyols are used to produce both the foam matrix (about 15%) and the PU elastomer (up to 90%).  The particles are about 1mm in size and used in different amounts according to foam density/stiffeness: 2.5% for “pillow grade” and 15% for “mattress grade”. The particles are claimed to improve heat conductivity and therefore comfort.
