绝缘阻水带 WATER BLOCHING TAPE
该产品采用聚酯纤维非织造布与高分子吸水材料复合而成，具有吸水膨胀功能。广泛用于光电缆产品，用于减少光电缆中水及潮气的渗入，提高光缆的工作寿命。
Water blocking tapes have an excellent swelling property.When water enters into a
cable protected by water blocking tape, the super absorbent powder within the tape instantly forms a water blocking gel,that prevents further and more costly damage to the cable.
