High temperature


TenCate provides a complete line of high temperature thermoset materials that can operate in temperature extremes of 260-371°C/ 500-700°F. The resins used for these composites consist of cyanate esters, polyimides and BMI’s. These high temperature materials provide both thermal stability and high temperature capabilities. TenCate Advanced Composites, in partnership with PROOF Research’s Performance Polymer Solutions (P2Si) offers a wide range of very high temperature polyimides with service temperatures in excess of 700°F/371°C. TenCate's high temperature materials are used in a variety of applications such as heat shields, missile fins, leading edges of supersonic aircraft and military jet engine components.


High temperature High temperature composites are used primarily in: 
  • Military applications 
  • Hypersonic applications 
  • Missile structures 
  • Launch vehicles 
  • Heat shields 
  • Jet engines ducts and afterburner structure

Featured product

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.
