The unfilled grade TECASINT 5111 natural is based on the high-performance plastic polyimide, which is characterised by its very good thermal stability with low thermal expansion. Polyimides are non-melting polymers with a service temperature of 300 °C, which is considerably higher than that of PEEK or PPS. In addition, TECASINT 5111 natural has a high creep resistance. These properties makes PI plastic ideal for applications where high temperature resistance is required, such as in the aerospace industry. TECASINT 5111 natural has good chemical resistance, especially to light acids and many organic solvents. In combination with the very good electrical insulating properties of the PI material, TECASINT 5111 natural is also perfectly suited for applications in the semiconductor industry, electrical engineering or mechanical engineering. Moreover, the polyimide material has good mechanical properties, good wear resistance and is also resistant to high-energy radiation.

Starting with the base polymer TECASINT 2011, the plastic TECASINT 2061 with 15 % graphite and 10 % PTFE has been developed.

TECASINT 8061 has been made from PTFE with a modification of 40 % PI. Compared with TECASINT 8001 it has a lower creep tendency under load, along with outstanding sliding and friction properties. The material is ideally suited to soft mating materials e.g. stainless steel, brass, aluminium or bronze.

TECASINT 5501 ESD light-brown is an electrically modified polyimide based on the further development of TECASINT 5111. By modifying it with special additives, the PI plastic has a static dissipative effect and thus achieves a surface resistance of 10 E6-10 E8 Ohm. The ESD material is therefore ideally suited for applications where electrostatic dissipation is to be ensured. Like all polyimide resins, TECASINT 5501 ESD light-brown is highly resistant to thermal and mechanical stress. The glass transition temperature is 329 °C and the short-term service temperature is 300 °C. In addition, the PI material is characterised by its high creep resistance. The PI Polyimide also offers a very low thermal expansion of 2.6 10-5 K-1, a high surface hardness and very good stiffness values. This makes TECASINT 5501 ESD light-brown suitable for applications in the semiconductor industry, electronics industry, cryogenics or in nuclear and vacuum technology.

TECASINT 1011 is an unfilled polyimide natural grade. This material particularly stands out in the TECASINT 1000 product family for very high strength and elongation. It is characterised by properties such as a very high modulus of elasticity, high rigidity, high degree of hardness and low thermal and electrical conductivity.
