LT-320 filling gel for optical cable

This filling gel has good performance at both high and low temperatures ,low acid value and hydrogen escape

    LT-320 filling gel is a kind of water-blocking compound which is made from mineral refined oil and hydrophobic tickening..It has a very good processing property and high-low temperature performance.It will remain soft at -40 and be free from droping flow at high temperature 80 .Its filling processing art is simple ,it can be easily filled at room temperature ,It is especially suitable for optical  cable jacket and cable core .Its viscosity can be set according to the requirement of users. Its properties are as follow:
