1. Higher thermal resistance, good impregnated property and dielectric properties. It is widely used in flexible laminates (DM, DMD, DMDM), reinforced material of mica tape, substrate of insulating varnish cloth, electrical laminated sheet.

2. 7030 is made by aerodynamic web-forming process. The distribution of its fibre is non-oriented., so the difference of tensile strength in MD and TD is small.

3. 7031 is made by mechanical web-forming process, so the tensile strength in MD is much higher than that in TD.

4. D711 Easy impregnated polyester non-woven fabric.
