Polyimides
Sintered TECASINT semi-finished products and direct formed parts have excellent long-term thermal stability. The wide temperature application range of this non-melting high-temperature polyimide ranges from -270°C to +300°C. Even when heated briefly to 350°C, the materials will not melt or soften. Strength, dimensional stability and creep resistance remain high under mechanical stress even during long-term usage.
The trend towards space and weight saving in modern mechanical and plant engineering applications results in increased thermal and wear resistance expectations in the materials used. The characteristic profile of the TECASINT product line addresses these stringent demands with outstanding success:
- High strength over a wide temperature range from -270°C to + 300°C
- Extremely good long-term thermal stability
- Glass transition temperature up to 400°C
- Good cryogenic properties
- Inherently flame retardant (UL 94 V0)
- Minimal thermal expansion
- Outstanding durability
- Excellent resistance to wear under high surface area pressure, high sliding speeds
- High compression strength pressure and creep resistance
- High radiation resistance
- High purity, low outgassing in vacuum
- Good chemical resistance to acids, fats and solvents
- Excellent electrical insulation properties
- Minimal thermal conductivity
Sintered semi-finished products can be manufactured using various production methods. TECASINT polyimides can be supplied in the form of:
- Semi-finished products (rods, plates, short tubes)
- Parts machined to drawing
- Volume parts using the direct forming process
Precision components made of TECASINT are produced in small production runs using machining processes in accordance with customer drawings. For larger volumes, components can be cost-effectively pressed and sintered using the direct forming process.
