P84 polyimide powder - precious like gold

TECAPOWDER P84 polyimides, the top end of high-performance plastics, are useful in various demanding applications in industries such as aerospace, semiconductor, automotive, aircraft, plasma-welding and diamond wheel. No other plastic material keeps more superlatives in its designation than polyimides. TECAPOWDER P84 is based on P84^® by Evonik. BTDA and PMDA monomers reacted with isocyanate to produce fully imidized polyimide resins without the need for post curing.

Since 1984 the production and the development of P84 has been situated in Austria, Lenzing. The Ensinger group is engaged in the development, manufacture and sale components made of engineering and high-performance plastics. Further development of proven production techniques, new applications and international expansion have earned the enterprise a place among the leaders in its field.

Delivery forms

TECAPOWDER P84 HCM grades are used to mould high-performance stock shapes. TECAPOWDER P84 STD can be used in composites.

TECAPOWDER P84 solution grade materials are for dissolving in DMF, DMSO or other polar solvents for use in speciality coatings.

TECAPOWDER P84 HT VPD grades are highly crosslinked which allows its use as a filler in many fluorpolymers. Small mesh sizes allow for good properties and uniform colour in sintered PTFE compounds.

TECAPOWDER P84 HCM blends contain various fillers for high-performance semi-finished parts based on the end use requirements. Graphite grades are excellent for bearing and wear resistance parts. Glass fibre grades are used for high strength and dimensional stability.

Industries

TECAPOWDER P84 for the glass industry

TECAPOWDER P84 parts can be used in the glass industry in applications such as bottle grippers with a higher productivity due to their properties: excellent temperature resistance, low thermal conductivity and a longer lifetime.

P84 for the semiconductor industry

The high electrical insulation and the low ion content of TECAPOWDER P84 HCM parts offer the ideal condition for applications in the semiconductor industry such as in test sockets or in chip and wafer manufacturing.

P84 for mechanical engineering

Various applications in mechanical engineering require demanding mechanical and tribological properties at temperatures above 200 °C (392 °F). For example, TECAPOWDER P84 resin can be used as a matrix material in diamond grinding wheels.

TECAPOWDER P84 for automotive sectors

TECAPOWDER P84 HCM parts can be used in various applications in the automotive sectors as they offer excellent mechanical stability under high continuous temperatures or high pV values in lubricated and unlubricated environments.

P84 for vacuum and cryogenic

Applications in vacuum and cryogenic technology require materials with good mechanical and tribological properties coupled with low outgassing values. Therefore TECAPOWDER P84 is the optimum solution for these fields of application.
