China Suppliers Factory Enameled Flat Wire with Solvent & Corrosion Resistance for Harsh Environments
Product Information
Designed to withstand harsh chemical environments, this enameled flat wire is fabricated from high-quality oxygen-free copper or electrical aluminum rod, processed through precision drawing and extrusion. It is specially suited for windings in electrical equipment operating in solvent-exposed or corrosive conditions, such as chemical industry reactors, marine electrical devices, and oilfield equipment. Based on insulating paint properties, it is classified into six categories with strong solvent and corrosion resistance:
- ●QQ/QQN (120℃): Polyvinyl Acetal/Self-adhesive Polyvinyl Acetal – good hydrolysis and transformer oil resistance
- ●QZ (130℃): Polyester – basic solvent resistance for general corrosive environments
- ●QZG (155℃): Modified Polyester – enhanced solvent and shock resistance
- ●QZY (180℃): Polyester Imide – excellent chemical solvent and heat shock resistance
- ●Q(ZY/XY) (200℃): Polyester Imide/Polyamide-Imide Composite – superior refrigerant, solvent, and radiation resistance
- ●QXY (220℃): Polyamide Imide – top-tier chemical solvent resistance

Frequently Asked Questions
Q
What types of insulation coatings are available for this enameled flat wire?
The enameled flat wire is available in six insulation categories: QQ/QQN (Polyvinyl Acetal, 120℃), QZ (Polyester, 130℃), QZG (Modified Polyester, 155℃), QZY (Polyester Imide, 180℃), Q(ZY/XY) (Polyester Imide/Polyamide-Imide Composite, 200℃), and QXY (Polyamide Imide, 220℃). Each type offers different levels of thermal and chemical resistance to suit specific application requirements.
Q
What conductor materials are used in the enameled flat wire?
The conductors are made from high-quality oxygen-free copper or electrical-grade aluminum rod. Both materials comply with GB5584 series standards, ensuring reliable and stable conductivity even when used in corrosive or chemically aggressive environments.
Q
What are the typical applications for this enameled flat wire?
