free flame-retardant. See the specification, page 6. The
partially adhesive coated expanded polymeric foam substrate also
has particular proportions of a plurality of expanded polymeric
microspheres. See the specification, pages 3, 4, 6 and 10. The
expanded polymeric microspheres are defined as “a polymer shell
and a core material in the form of a gas, liquid, or combination
thereof.” See the specification, page 9. “Examples of suitable
commercially available expandable polymeric microspheres include
those available from Pierce Stevens (Baffalo, N.Y.)... [and]
Akzo-Novel... The amount of expandable microspheres is selected
based upon the desired properties of the foam article.” See the
specification, page 10. According to page 6 of the
specification, “[t]he fire retardant materials suitable for
inclusion herein include any of a variety of such substances, but
preferably comprise materials that are non-halogenated and
antimony-free.” “Although fire retardant materials are normally
excluded from the formulation for the adhesive, small amounts of
fire retardant may also be included within the adhesive at
concentrations that are effective to impart fire retardant
properties...” See the specification, page 17. Various
