Solvay DURATOOL® 450 BMI Tooling Prepreg
Categories: Polymer; Thermoset; Bismaleimide (BMI)

Material Notes: Description: DURATOOL 450 is a proven, high-performance bismaleimide (BMI) resin/carbon fiber tooling system that is capable of continuous service at 375°F (190°C) and short cycle service at 400°F (204°C). DURATOOL 450 allows high-quality tooling laminates to be produced directly from a high-temperature master models or a variety of intermediate materials. After autoclave processing for the initial cure, the tool laminate can be de-molded and post-cured “free-standing”. DURATOOL 450 is supplied in roll form with a standard roll length of 50 yards (50 meters). Standard material width is 50 inches (1000 – 1250mm). Materials are shipped frozen and in insulated boxes.

Features & Benefits:

  • Proven capable of more than 1000 autoclave cycles at 375°F (190°C) without deterioration
  • Manufactured to ensure uniform resin distribution in fabrics with <1% volatile content
  • Formulated for long term thermal oxidative stability during normal 375°F (190°C) service
  • Exhibits low and predictable shrinkage allowing manufacturing process design to net size tool
  • Closely matches the thermal expansion coefficient of composite parts reducing dimensional inaccuracies and residual stress levels
  • Determined safe to use via extensive toxicological screening (contains no MDA or VCHDs)
Suggested Applications:
  • Ideal for multiple-tool/high-production-rate manufacture of composite components
