Definitions

  • Tensile tests measure buildup of force (or stress) as the specimen is stretched at a constant rate. It yields force (and thus strength) values, and the results are close to those of the melt test at the melt temperature of the material.
  • Samples having an average size of 0.6 x 0.5 x 0.1 mm were prepared as in the DMTA test, wherein the first value (0.6) is the gauge length.
  • Tensile strength is measured with a Model 1101 Instron using a 100-pound load cell and a cross-head speed of 20 inches per minute at 165 °C. As measured by this test, compositions comprising SANTOPRENE, EPDM and PP 6823 showed higher elongation and toughness. Samples comprising 20% SS fibers show result comparable to those without (data not shown).

Abstract

L'invention porte sur une mousse élastomère, thermoplastique, micro-cellulaire, de faible densité, comportant des alvéoles fermées. Cette mousse est fabriquée à l'aide d'un fluide supercritique utilisé comme agent gonflant. La chute de pression dans la matrice est comprise entre environ 0,1 et environ 4,8 GPa, et la température de fusion de la composition de résine est comprise entre environ 320 et 360 °C.
