Polyimide Materials

ENSINGER has extended its amorphous, nonmelting high-temperature polyimides product line. TECASINT includes several new developments and modifications, as well as proven materials under the brand name SINTIMID. The company introduced semi-finished products and direct-formed parts made of the new material TECASINT 2000, which is characterized by improved toughness. TECASINT has outstanding long-term thermal stability. The broad temperature range of these materials extends from -270° C to 300° C with short-term heating up to 350° C without melting or softening. Material strength, dimensional stability and creep resistance under mechanical load also remain high in continuous use.

TECASINT 2000 is eminently suitable for the direct forming procedure, which allows economical volume production of parts, for example, in automotive industry and mechanical engineering. ENSINGER offers the new product in different tribologically optimized variations for use in sliding friction applications. The basic monomers, TECASINT 1000 and 2000, can be categorized in the “high purity” class which is important for wafer production.

TECASINT 5000 (previously: SINTIMID PAI) is a nonthermoplastic processible high-temperature polyamideimide.

TECASINT 5000 is available as the pure material, glass-fibre reinforced or in different electrostatic dissipating variations, which can achieve surface resistances from 1012 to below 103 Ω. Products of the series TECASINT 8000 (SINTIMID 8000) are proven materials for sliding friction applications. The base material PTFE is reinforced by PI powder in proportions of 7% to 40%. TECASINT 8000, which is available as semi-finished products (plates, rods) and as sliced film sheeting, is suitable for soft counterparts such as aluminium, brass or bronze.

TECASINT is available from stock as plates and rods in different dimensions. ENSINGER also supplies short tubes made of TECASINT 1000, 2000 and 8000 up to a length of 180 mm with a maximum outside diameter of 120 mm.
