Nylon 66 (loosely written nylon 6-6, nylon 6/6, nylon 6,6, or nylon 6:6) is a type of polyamide or nylon. It, and nylon 6, are the two most common for textile and plastic industries. Nylon 66 is made of two monomers each containing 6 carbon atoms, hexamethylenediamine and adipic acid, which give nylon 66 its name. [1]

Jul 30, 2021 · Nylon 6 is a cast material that has a slightly lower continuous service temperature rating than Nylon 6/6 but can endure a higher combination of load and speed in bearing applications (commonly displayed by a PV rating).

Nylon 6 has about 20% greater moisture absorption than Nylon 6/6. So Nylon 6 is on the higher end of the property change, while Nylon 6/6 is on the lower end of the property change. See below for a comparison of properties for unfilled and 33% glass reinforced Nylon 6 and Nylon 6/6.

Designed for extreme wear resistance, this Kevlar-filled nylon 6/6 material lasts up to 20 times longer than unfilled nylon. Also known as Hydlar Z, it is often used for parts that are continuously exposed to wear and abrasion, such as wear strips and bushings.

Sep 5, 2013 · Nylon 66 is superior in many applications to nylon 6—the other large volume nylon—due to its outstanding dimensional stability, higher melting point, and more compact molecular structure (see below figure). Nylon 66 exhibits only about half the shrinkage of nylon 6 in steam, for instance.

Jan 15, 2020 · Nylon 6.6 offers low creep, good stretch recovery, and higher abrasion resistance than Nylon 6 and most other materials you’ll find in the marketplace. In fact, its abrasion and heat resistance are the defining properties that make it a superior choice for industrial applications.

Sep 11, 2023 · Nylon 6/6 is similar to Nylon 6 but features a few key distinguishing features: Chemical resistance. Compared to Nylon 6, Nylon 6/6 is more resistant to acids, making it a better option for applications exposed to harsh chemicals. Higher service temperature range.

Feb 21, 2025 · Nylon 6 vs nylon 6/6: Learn how these two polyamides compare in strength, durability, water absorption, and industrial applications.

Extruded nylon type 6/6 is characterized as having an excellent combination of physical properties including a high melting point, resistance to repeated impacts, low coefficient of friction, and a resistance to abrasion.

Jan 7, 2024 · Ever wondered about the intricate structure of nylon 6-6? Understanding the molecular composition and crystal structure of this polymer can offer valuable insights into its properties and applications.
