Non-weft tape

This type of non-weft tape is woven by the glass fiber without any alkali and then, processed in the heat resin. And it is well known by its own mechanical strength and rigid structure and can be against any tension from every binding layer.

This tape will be widely used in many industries, such as chemistry, electricity, machinery, etc. Because of its good performance. For example, it can be coiled around the outer and inner cases of high voltage coil and other high voltage appliance to avoid any heavy shake and noise from transformers. In chemistry industry, for the binding material of electric industry instead of any type of anti-magnetic alloy wire as the binding material around armature, hollow screw of transformer, fixed iron core, mutual inductance insulator.
