Non-Conductive Double-Layer Water Blocking Tape

Non-Conductive Double-Layer Water Blocking Tape

These Tapes are laminated by polyester non-woven fabric layer and super swelling water absorbent powder. Due to the high swelling speed and excellent swelling height, it can easily block water and moisture to protect your cable.

Composition:

  1. Polyester Non-woven Fabric
  2. Polypropylene Super Absorbent Powder
  3. Polyester Non-woven Fabric
