click to resize photo TecaTor is a high performance amorphous (non-crystalline) engineering thermoplastic available in sheet, rod or tube forms produced from Torlon® resin by Ensinger. Chemically, Torlon ® is a polyamide-imide (PAI), a reaction product of trimellitic anhydride and aromatic diamines. It is called amide-imide because the polymer chain comprises amide linkages alternative with imide linkages. The combination of aromatic groups and imide linkages are responsible for the polymer's exceptional thermal stability. The amide groups impart flexibility and elongation, which results in an engineering plastic with exceptional toughness.

TECATOR is the highest performing melt processable plastic. It has superior resistance to elevated temperatures. It is capable of performing under severe stress conditions at continuous temperatures to 500°F (260°C). Parts machined from TECATOR stock shapes provide greater compressive strength and higher impact resistance than most advanced engineering plastics. Its extremely low coefficient of linear thermal expansion and high creep resistance deliver excellent dimensional stability over its entire use range. TECATOR is an amorphous material with a Tg (glass transition temperature) of 537°F (280°C).

TECATOR TI5013 (Electrical Grade)
TECATOR TI5013 extruded PAI offers excellent compressive strength and the highest elongation of the TECATOR grades. It also provides electrical insulation and exceptional impact strength. This grade is commonly used for electrical connectors and insulators due to its high dielectric strength.

TECATOR TI5031 (Bearing Grade)
TECATOR TI5013 extruded PAI is primarily used for wear and friction parts. It offers a very low expansion rate, low coefficient of friction and exhibits little or no slip-stick in use. TECATOR TI5013's flexural modulus of 1,000,000 psi is higher than most other advanced engineering plastics. This grade excels in severe service wear applications such as non- lubricated bearings, seals, bearing cages and reciprocating compressor parts.

TECATOR GF30 (XP142T) (Glass-Reinforced Grade)
TECATOR GF30 (XP142T) is 30% glass reinforced, compression molded PAI. It is ideal for higher load structural or electronic applications. It is selected for larger shapes or when the greatest degree of dimensional control is required. Applications include burn-in sockets, gears, valve plates, impellers, rotors, terminal strips, and insulators.
