Aromatic Polyamide Paper Tubing

Dimension

Inside diameter 2.0-65(mm),Thickness 0.05-1(mm), Length 10-1000(mm)

Color

Natural color, clear, yellow, stripe available

Dielectric Strength

After polishing, it can withstand 18~40KV/mm short time voltage field strength. It is not necessary to do further treatment with vanish or resin. Due to the low dielectric strength of Aromatic polyamide paper product, the electric field is distributed averagely between insulation and cooling dielectric.

Mechanical Tenacity

Excellent intensity, high flexibility, high performance of wear resistance

Thermal Stability

Compliant with UL standard and can work under 220°C stably more than 10 years.

Chemical Compatibility

Resistance to acid and alkali. It is compatible with all varnish, adhesive, transformer liquid, lubricant and coolant. Beside, Aromatic polyamide paper is not easy to be destroyed by insect, epiphyte and mildew.

Low Temperature Performance

In the boiling point(77k)of nitric, the strength of T410insulation paper and Aromatic polyamide paper exceed the strength under room temperature

Humidity Resistance

Although the product is wet more than 95%, its dielectric strength is totally dry in 90%. Consequently, many mechanical characteristics changed

Radiation Resistance

Even though the ionization strength up to 800 Mrad (8MGy), Aromatic polyamide paper won’t be affected. Moreover, it will maintain its mechanical and electrical properties after 8 times radiation.

Non-toxic/fire Endurance

It is no harmful to human and environment. It doesn’t melt in air. It’s fireproof. Its oxygen restriction index is higher than 20.8 in 220°C, so it won’t catch fire. Aromatic polyamide paper products compliant with all restrictions in UL94 V-0 standard.
