Nylon 6-6

Nylon 6,6 is one of the most widely used types of polyamides, which is used in various industries due to its favorable mechanical, thermal and chemical properties.

Structure and properties of nylon 6,6

Nylon 6,6 is a semi-crystalline polymer formed by the reaction of hexamethylene diamine (a diamine) with adipic acid (a diacid). This regular structure gives nylon 6,6 excellent mechanical properties such as tensile strength, abrasion resistance and hardness.

Important properties of nylon 6,6

High strength: Nylon 6,6 has high tensile and compressive strengths, making it suitable for applications that require mechanical strength.
Abrasion resistance: The surface of nylon 6,6 has good resistance to abrasion and friction.
Good chemical resistance: Nylon 6,6 is resistant to many chemicals such as oils, greases and many solvents.
Low moisture absorption: Compared to nylon 6, nylon 6,6 absorbs less moisture, which gives it better dimensional stability.
High processability: Nylon 6,6 can be easily processed in various ways such as injection, extrusion and molding.

Applications of Nylon 6,6

Automotive industry: Production of interior car parts such as seat covers, dashboards and engine parts
Electrical and electronics industry: Production of electrical insulators, connectors and electronic components
Packaging industry: Production of packaging films, bottles and containers
Textile industry: Production of fibers for making fabrics, carpets, ropes and…
Medical industry: Production of medical equipment such as surgical thread, prostheses and parts of medical devices
