Features of chalco high heat resistant poIyesterimide enameIIed round aluminum wire
Advantages
- Having good paint film toughness and scratch resistance, suitable for automatic wire winding and embedding.
- It has good Thermal shock and excellent softening breakdown performance, and is suitable for high temperature, overload and heavy load motor and electrical products.
- In addition to strong acids, chloride ion salts, and organic compounds, it has good resistance to acids, alkalis, and most organic solvents.
- Direct soldering polyester imide enameled wire does not require removing the paint film and can be directly welded at a welding temperature of 450-500 ℃.
- The polyamide outer composite coating is generally 2-5um, which further improves the elasticity and scratch resistance of the paint film and can also reduce salt water pinholes.
Limitations
- Easy to hydrolyze in aqueous sealing systems (attention should be paid when sealing motors and electrical appliances).
- Incompatible with PVC, Neoprene and other chlorine containing polymer compounds.
- Slightly poor adhesion of paint film.
- In water containing chloride ions, a significant decrease in voltage is generated and the brittleness of the paint film increases.
- Poor conductivity of aluminum wire.
- Excellent electrical insulation properties: Polyesterimide coating provides high electrical insulation properties, so that the coated aluminum round wire can operate safely in high voltage and high electric field environments.
Precautions for purchasing poIyesterimide enameIed round aluminum wire
Application environment: Consider your application environment. If your application requires corrosion resistance or specific high temperature resistance, be sure to select polyesterimide enamelled aluminium round wire that meets the relevant requirements.
Cost effectiveness: Weigh the price/performance ratio. Compare the price and quality of different suppliers or brands and look for products with good performance and reasonable prices.
Customer support: Understand the supplier's customer support and after-sales service. Ensure that suppliers are able to provide technical support, product consultation and after-sales support.
Order quantity: Determine the appropriate order quantity based on your needs. Sometimes you can get better prices and discounts by ordering in bulk.
