摘要： Thermoplastic vulcanizate blends, or a reaction product thereof, that include at least one propylene resin, at least one ethylene/alpha-olefin/non-conjugated diene elastomer, a curing system, and at least one co-agent may be formed into a foamed blend by the addition of a plurality of expandable polymeric microspheres. Methods of forming such foamed blends and resultant articles are also included. Compared to an equivalent non-foamed blend, such foamed blends are characterized by features that may include low thermal conductivity and decreased density in a closed cell structure with accompanying small cell size, good processability, and colorability.
