In addition to the sintering process used to produce stock shapes, finished components can be cost-effectively produced in larger quantities using the direct forming process. PI plastics are used everywhere where very high or cryogenic temperature resistance is required. Even above 260 °C, dimensional stability, strength and creep resistance remain high. For wear and friction applications Polyimides are the ideal material due to the ability to work under unlubricated conditions, low wear rates and high pV-rates. Thus lifetimes are extended and maintenance costs reduced. Polyimide applications can therefore be found in a wide range of industries.For aerospace and semicon industry the high purity and low outgassing are additional benefits of Polyimide plastics. POLYIMIDES HAVE EXCEPTIONAL PROPERTIES FOR HIGH PERFORMANCE APPLICATIONS Long-term thermal stability 300 °C (short-term up to 400 °C) High heat resistance up to 470 °C (HDT/A) Good cryogenic properties down to -270 °C High strength, modulus and stiffness also at high temperatures over 260 °C Excellent wear resistance under high surface pressure and high sliding speeds Excellent thermal and electrical insulation Minimal thermal conductivity High purity, low outgassing in vacuum conditions in accordance with ESA regulation ECSS-Q-70-02 Good machinability Good chemical resistance to acids, fats and solvents Inherently flame retardant (UL 94 V0) TECASINT PRODUCT FAMILIES The materials belonging to the polyimide group are characterised by an unusually complex property profile with a large number of excellent individual characteristics and so take up a position at the tip of the material pyramid. Ensinger offers rods, plastes and tubes as well as customized direct formed parts. Polyimides (PI) are produced by polycondensation. They are non melting due to the high amount of ring-shaped, mostly aromatic chain links and high molecular weights. The manufacturing of semi-finished products or direct-forming parts is therefore done exclusively by sintering techniques.

They can be used to implement applications involving the most extreme conditions, and are used for applications in the automotive industry requiring mechanical stability under high continuous temperatures or high pV values in lubricated and unlubricated environments. Use of the direct forming method allows the economical manufacture of serial parts complying with the narrowest of tolerances.

DETAILS DIRECT FORMED POLYIMIDE PARTS FOR HIGH VOLUME PRECISION PARTS Direct forming is a cost effective manufacturing method for producing high volume precision parts. Direct formed Polyimide parts are typically used for applications in the automotive industry or for large quantity production, when machining shapes is too expensive. Fast running presses (mechanical or hydraulic) compact the powder in the mould cavity. The mouldings are then sintered for some hours at high tem­per­a­tures with the exclu­sion of oxygen. The direct forming technique in­volves practically no material waste. In most cases, reworking is also not required. DETAILS MACHINED PARTS Alongside the manufacture of stock shapes and direct forming parts, the TECASINT materials can be machined with ease. Complex, tight tolerance components can be produced on standard milling machines and turning lathes. For optimal results, specific plastic cutters should be used. TECASINT can be machined in a dry state or with coolant if necessary. DETAILS CASE STUDY: TECASINT GOES TO MERCURY THERMAL SPACER made of TECASINT With Bepi Colombo to Mercury Ensingers TECASINT material is part of Europe's first mission to Mercury with BepiColombo. The spacecraft for the mission are dependent on the function of the thermal control system (TCS), which keeps all the spacecraft's component systems within an acceptable temperature range during every phase of the mission. One part of the TCS is a thermal spacer, which functions as a barrier to high temperatures and radiation. This thermal spacer is a ring shaped plate made of TECASINT.
