The invention described relates to formed profiles comprising
microcellular TPE foam compositions, and articles therefrom, wherein the
TPE are thermoplastic vulcanizates. The foamed thermoplastic elastomer
profile comprises a foamable thermoplastic elastomer composition having
a) a cross-linkable hydrocarbon rubber in the presence of b) a
thermoplastic polyolefin resin having a Tm greater than 120.degree. C.
wherein said composition further comprising: a) 25 to 30 wt % of a
partially or fully vulcanized reaction product of said cross-linkable
hydrocarbon rubber with a cross-linking agent, said reaction product
being present as a dispersed phase; b) 7 to 12 wt % of said thermoplastic
resin as a continuous phase; c) 8-22 wt % of an elastomeric thermoplastic
modifier comprising 1) 3-7 wt. % copolymers of propylene with one or more
of ethylene and C.sub.4-C.sub.10 alpha-olefins, said copolymers having a
Tm greater than 20.degree. C. and less than 120.degree. C., and, 2) 5-15
wt. % hydrogenated, triblock styrenic copolymers from styrene and
isoprene; and, optionally, d) 3-12 wt. % solid filler; and/or e) 35-45
wt. % of non-aromatic hydrocarbon oil; wherein said wt. % amounts are
based upon the total weight of the composition, and where the composition
has been prepared by a process comprising dynamically vulcanizing said
composition. The foamed thermoplastic elastomer profiles having smooth
surfaces, improved low water absorption, improved compression set and
compression load deflection.
