The main body of the water blocking tape for optical cables is composed of polyester fiber nonwoven fabric and high water absorbing material, which has the function of water absorption and expansion. Widely used in optical cable products to reduce the infiltration of water and moisture in optical cables and improve their service life.
1. It has characteristic of strong moisture absorption, big expansion rate and quick expansion velocity;
2. Small resistance, can buffer and weaken the electrical field strength effectively;
3. High mechanical strength makes it easy to be wrapped and longitudinal wrapped for kinds of cables;
4. Double sided water proof tape is heat-resistant and can bear hich instant temperature. Cable with this product can keep stable performance;
