Dupont Nomex 410

Description

NOMEX is a heat-resistant, high-strength material made of meta-aramid. It has excellent thermal stability and is stable at a temperature of 250°C. NOMEX needle punched products are mainly used in high temperature filter materials and insulation materials. In addition, NOMEX is non-toxic, flame retardant and has good electrical and mechanical properties. DuPont produces a product called NOMEX paper, which is an aromatic polyamide with a particularly stable molecular structure, which is the source of NOMEX's excellent performance.
DuPont insulating paper NOMEX T410 description: This is the prototype of NOMEX paper. It is widely used in most electrical equipment. Its thickness is 0.05~0.76 mm (2~30 mils). Its specific gravity is 0.7~1.2. Due to the calendering treatment, its Intrinsic dielectric strength, mechanical properties, flexibility and elasticity are high. NOMEX Type 410 can be used with almost all known sheet insulations. . It is available in 12 thicknesses (0.05-0.76mm) (2-30mil) and is used in almost all applications where electrical sheet insulation is known to be required. If necessary, you can contact Zhou Sheng of Guangzhou Guchen Industrial.

he Nomex insulation paper is a three-ply laminate with polyester film between two layers of Nomex® paper.
About the Nomex paper:
Ideally suited for a variety of temperature ranges and applications, laminate insulation products based on Nomex® paper help enhance the performance and reliability of rotating machines.
About the polyester film: It has excellent mechanical properties, dielectric strength, and dimensional stability, as well as low water absorption, and good resistance to most chemicals. These general purpose films are often used for industrial laminates and electric motor and cable insulation.
The NMN laminates made with Nomex® papers are used in UL systems typically up to 180°C. These laminates are broadly used in the production and repair of motors, generators of many sizes and temperature classes. The most important applications for these laminates are slot liners, wedges and phase insulation in Class H motors and generators, as well as in large and specialty Class F motors.
