What are the properties of polyamide-imide?

Polyamide-imide Material Properties

Is polyamide-imide nylon?

Polyamide vs Polyimide Polyimides are made of imide linkages (-CO-N-OC-). Polyamides are synthesized by the polymerization between diamines and dicarboxylic acid. Polyimides are synthesized by the polymerization between dianhydride and diisocyanate or diamine. Common trade names are Nylon and Kelvar.

Is torlon a thermoplastic?

Torlon® polyamide-imide (PAI) is the highest performing, melt-processable thermoplastic. The amorphous polymer has exceptional resistance to wear, creep and chemicals and performs well under severe service conditions up to 260°C (500°F).

What kind of material is Torlon?

Polyamide-imide
PAI (polyamide-imide) is a melt-processable plastic that has exceptional physical and chemical properties. It performs well under severe stress conditions at continuous temperatures as high as 500° F. Torlon® is an amorphous material with a Tg (glass transition temperature) of 537° F.

What is polyamide imide used for?

Polyamide-imides are used extensively as wire coatings in making magnet wire. They are prepared from isocyanates and TMA (trimellic acid-anhydride) in N-methyl-2-pyrrolidone (NMP). A prominent distributor of polyamide-imides is Solvay Specialty Polymers, which uses the trademark Torlon.

What is vespel used for?

Vespel is mostly used in aerospace, semiconductor, and transportation technology. It combines heat resistance, lubricity, dimensional stability, chemical resistance, and creep resistance, and can be used in hostile and extreme environmental conditions.

Is polyamide a thermoplastic?

Polyamides or Nylon is a major high performance engineering thermoplastics class because of its good balance of properties. Polyamides contain repeating amide linkages i.e. –CO-NH–. It is formed by condensing identical units, copolymers with different units.

What is polyamide-imide used for?

What is vespel material?

Vespel® is a high-performance polyimide-based thermoplastic material with notable characteristics: it withstands wide temperature ranges; it is wear and chemical resistant; it has excellent mechanical and insulation properties; it has natural lubricity; and unlike most polymers, it does not produce significant …

What is imide group?

In organic chemistry, an imide is a functional group consisting of two acyl groups bound to nitrogen. The compounds are structurally related to acid anhydrides, although imides are more resistant to hydrolysis.

Can vespel be injection molded?

To make this “plastic of last resort” more versatile, DuPont has developed new polyimide materials suitable for injection molding. The company will use the materials to make “Vespel TP” custom molded parts in the U.S., Europe, and Asia.

Which is the highest Performance Polyamide-imide thermoplastic?

Torlon® polyamide-imide is recognized as the highest performance thermoplastic that is still melt processible. Torlon can be extruded into shapes and injection molded into custom geometries.

What kind of material is Polyamide imide used for?

Polyamide-imides are either thermosetting or thermoplastic, amorphous polymers that have exceptional mechanical, thermal and chemical resistant properties. Polyamide-imides are used extensively as wire coatings in making magnet wire.

What are the properties of Torlon Polyamide imide?

Torlon® polyamide-imide offers outstanding insulation properties and high dielectric strength. Characteristics include: Contact a Dielectric Manufacturing knowledge expert to discuss the use of Torlon polyamide-imide for fabrication of your thermoplastic parts. Call 800-367-9122 or email [email protected].

What should the mold temperature be for Polyamide imides?

The starting mold temperatures are specified as follows: The mold temperature should be in the range of 325 °F to 425 °F (163 °C to 218 °C). The high temperature and chemical resistance of polyamide-imides make them in principle suitable for membrane based gas separations.
