2.Electrical insulation

It’s highly electrical insulated. Its dielectric strength can be over 10kv/mm being untreated with insulating varnish or resin. Because of its excellent thermal stability, it still remains good electrical properties during continuous operation at high temperature. As the dielectric constant is very low, it distributes the electric field evenly. And its low dissipation factor can make running dissipation less, so it is of environmental friendly insulating material.

 

Dielectric performance: thickness 0.08mm at normal temperature.

3	Dissipation factor	%	0.7	ASTM D257
4	Dielectric constant		1.7	ASTM D257

3. Good mechanical properties

It is sheet material made of aramid fiber of high density, smooth surface, good toughness, high tensile strength and tear strength.

4. Chemical stability

 

Its molecules are of big linear molecules composed of aryl residues connected by aramid bridge. In its crystal, hydrogen bonds array in two planes into three-dimensional structure. Strong hydrogen bonds ensure its stable structure and excellent properties of resistance to some chemicals such as most of the inorganic acid, most of other chemical reagent and organic solvent.
