Know Everthing About PAI plastic - Polyamide imide

August 01, 2024

Learn about the origins of PAI:

PAI plastics were first developed in 1964 by the Amoco Research Institute in Napervill, Illinois, U.S.A. In 1965, a trial run of insulating paint was made, and in 1971 the product was marketed under the trade name TORLON.

Understand the chemical structure of PAI:

PAI (Polyamide Imide Terylene / TORLON) is usually made by polycondensation of phenyltrimellitic anhydride and diisocyanate in a DMF solution. Due to the stable aromatic heterocyclic structure in its molecule, PAI exhibits heat and low-temperature resistance unmatched by other polymer materials

Learn about the characteristics of PAI:

High temperature resistance:

It exhibits excellent mechanical properties and dimensional stability in high temperature environments. It has the best dimensional stability in the 250°C temperature range, and is able to reach up to 275°C (525°F) while still maintaining

its toughness, high strength and stiffness.

Resistant to abrasion:

Excellent wear resistance in both dry and lubricated environments, which can be further enhanced with the addition of carbon fiber and polymeric lubricants such as PTFE.

High Strength:

High strength, stiffness and impact resistance make it excellent for mechanical and structural applications.

Chemical resistance:

Demonstrates a wide range of chemical resistance to strong acids, alkalis and most organics.

Creep resistance:

Exhibits very high creep resistance and maintains its mechanical properties even at high temperatures.

Low coefficient of linear thermal expansion (CLTE):

The low coefficient of linear thermal expansion (CLTE) allows for minimal dimensional changes during temperature changes, making it suitable for precision component applications.

Self-lubricating:

The self-lubricating properties allow it to operate under inadequate lubrication conditions, reducing friction and wear.

Low Flammability:

Has inherently low flammability, making it suitable for use in applications requiring fire safety.

Radiation Resistance:

Has superior resistance to high energy radiation, making it suitable for use in high radiation environments.

Electrical Insulation:

Possesses high insulating properties, making it suitable for use in electrical components and electronic equipment.

Processability:

Can be molded by injection molding and other processes to form a variety of complex shapes of precision products, high production efficiency.

PAI material has these characteristics support make PAI become the ideal material choice for many demanding applications, especially in the need for high temperature performance and precision machining scenarios are very widely used.

Areas of application for PAI plastic materials

PAI (polyamide-imide) is an engineering plastic with excellent properties and is used in a wide range of applications. The following are examples of some of the areas in which PAI is used:

1.Lighter rod

Customers customized non-standard parts, the specific use is not quite clear, must be the characteristics of PAI material, choose this material.

a. PAI lighter rod with high conductivity and resistance to high temperature and high pressure, in the need for high-voltage discharge applications stand out. For example, in the LED wire soldering machine, PAI lighter rod is used to generate high-pressure discharge, the gold wire, copper wire,

Alloy wire and other media melt off the burning ball, this process is also known as EFO (Electric Field Oxidation) role.

b. PAI material's relative electrical conductivity, tensile strength and Brinell hardness and other characteristics make it in the application of the lighter rod has an advantage. For example, the high electrical conductivity and high tensile strength of PAI material make it stable in the high-voltage discharge process.

Can work stably in the high-voltage discharge process, while its high Brinell hardness provides good abrasion resistance.

c. Industrial applications:

PAI lighter rods are used in high-energy igniters in places such as industrial kilns and boilers. These igniters usually consist of an igniter, a lighter rod, and an ignition cable. The high temperature and high pressure resistance of PAI material makes it

PAI material's resistance to high temperatures and high pressures allows it to perform well in these high-temperature environments....

d. Wire Bonding Ignition: PAI ignition rods are also widely used for wire bonding ignition. All wire bonding lighters are available on the market and are customized for retrofitting. These rods play a key role in the welding process, ensuring a quality weld.

They play a key role in the welding process, ensuring the quality and stability of the weld.

2. Aerospace:

PAI materials have excellent ablation resistance and electromagnetic properties at high temperatures and high frequencies, and can be used as ablation materials, magnetically permeable materials and structural materials for aircraft.

3.Automotive:

PAI materials are also used in the automotive industry, mainly for the manufacture of high-temperature and wear-resistant components, such as seals, pump and valve components, bearings and bushings.

4.Semiconductor and Microelectronics:

PAI materials are used for semiconductor test parts, processing inserts, wafer combs, microelectronic IC test holders and contacts.

5. Mechanical and structural components:

PAI materials are commonly used in the manufacture of mechanical parts such as gears, rollers, bearings, and separating jaws for photocopiers due to their high strength and wear resistance.
