Solvay MTM® 70
Categories: Polymer; Thermoset

Material Notes: Description: MTM70 is a toughened, variable cure temperature prepreg matrix formulated for the manufacture of structural components operating at elevated service temperatures. After 135°C (275°F) standard cure cycle. MTMT70 provides excellent mechanical performance for components operating at up to 140°C (284°F). After post-cure to 180°C (356°F), MTMT70 will operate at higher temperatures without significant loss of toughness.

Features & Benefits:

  • 30 days out life at 21°C (70°F)
  • 12 months storage life at -18°C (0°F)
  • Initial cure temperatures between 85°C and 180°C (185°F to 356°F)
  • Tg steps ahead of cure temperature
  • Good mechanical performance with intermediate and high modulus fibers
  • Variable cure temperature capability
  • Excellent retention of mechanical properties at elevated temperatures
Note 1: Cure cycle: 1.5 hrs at 135°C (275°F), 6.2 bar (90 psi)
