PolyImides (PI)

Polyamides are a group of engineering polymers that have found widespread use in advanced industries due to their excellent thermal, chemical, and mechanical properties. These polymers are known as one of the most durable polymer materials due to their very high resistance to heat, friction, and chemicals.

Properties of Polyamides

Excellent thermal resistance: Polyamides can be used at very high temperatures without decomposition and have good resistance to thermal shock.
High chemical resistance: They are resistant to a wide range of chemicals, solvents and corrosive environments.
Excellent mechanical properties: They have high tensile strength, Young’s modulus and creep resistance.
Good electrical insulation: They are very good electrical insulation and are widely used in the electronics industry.
Good dimensional stability: They resist deformation due to heat and humidity.

Types of Polyamides

There are different types of polyamides, each with specific properties and applications. Some of the important types of polyamides are:

Aromatic polyamides: They have very high thermal and chemical properties and are used in the aerospace and electronics industries.
Aliphatic-aromatic polyamides: They are a combination of the properties of aromatic and aliphatic polyamides and are used in various industries.
Cyclic polyamides: have very high thermal and chemical properties and are resistant to solvents.

Applications of polyamides

Polyamides are used in various industries including aerospace, electronics, automotive, energy and medicine. Some of the important applications of polyamides are:

Aerospace industry: production of aircraft parts, satellites and missiles
Electronics industry: production of flexible printed circuits, electrical insulators and electronic components
Automotive industry: production of automotive parts such as brakes and engine parts
Energy industry: production of solar cells and batteries
Medical industry: production of medical implants and surgical equipment
