High temperature


Operating in temperature extremes of 260-371°C/ 500-700°F, TenCate's line of cyanate esters, polyimides and BMI’s are up to the test.  Offering thermal stability and long term high-temperature performance, these unique materials replace titanium and other nickel alloy metals in heat shields, missile fins, hypersonic aircraft and military jet engines. In partnership with PROOF Research’s Performance Polymer Solutions (P2Si), TenCate prepregs P2Si's polyimide resins on a variety of carbon and ceramic reinforcements.       


High temperatureTenCate's high temperature advanced composites are valued in: 
  • Military applications 
  • Hypersonic applications 
  • Missile structures 
  • Launch vehicles 
  • Heat shields 
  • Jet engines ducts and afterburner structure

TenCate TC420 
TenCate's TC420 is a flow-controlled, high-temperature cyanate ester resin, toughened to resist microcracking. TC420 is specifically formulated for the production of large out-of-autoclave structure and can act as a self-adhesive system within the structure.  TC420 is available in a variety of formats, including fabric and unitape prepregs.  Additionally, TC420 is offered with a compatible film adhesive, syntactic paste and expanding foam. This resin system is easy to process and yields low void laminates through a flexible cure cycle under vacuum-bag-only pressures.  TC420 is also well suited for processing in an autoclave.
