Factory best selling Half Blind Box Joint - semi-conductive water blocking tape – Siber Detail:

SIBER 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.

SIBER water blocking tapes are available not only semi-conductive but also non-conductive,PET laminated versions to suit diverse cable applications.
