Water Blocking cable filling Jelly

Short Description:

Cable jelly is a chemically stable mixture of solid, semi-solid and liquid hydrocarbon. The cable jelly is free from impurities, have a neutral smell and contain no moisture.

In the course of plastic telephone communication cables, people come to realize that due to plastic has a certain moisture permeability, resulting in the cable there are problems in water terms, often resulting cable core is water intrusion, the impact of communication, the inconvenience of production and life.

General Description of Cable Jelly

In addition, pinholes and local damage plastic sheath may result in moisture from entering the cable core, the cable electrical characteristics deteriorate. It further found that the cable jacket damage is not necessarily the place where the transmission characteristics deteriorate, which gives the cable maintenance and troubleshooting a lot of trouble, so in the manufacturing process of the cable, usually three ways to ensure moisture-proof and waterproof cable that is inflated or filled with petroleum jelly using super-absorbent material, which with petroleum jelly at home with a little bit more common. Petroleum jelly filled cables, fiber optic cable all the gap, among waterproof seal plays the role of the optical fiber from the external environment, extending its life, and no maintenance can maintain long-term stability and reliability of fiber optic transmission.

Application of Cable Jelly

In the cable industry, cable jelly is used primarily for the production of phone cables with copper wiring, cable jelly is also classified as petrolatum filling compounds

Packing of cable jelly.

Cable jelly should be packed in steel drums or flexi tank to avoid any leakage during transportation.


● The LF-90 has a very good compatibility with most polymer materials, and it has a very good compatibility with steel and aluminum materials.

● Recommended compatibility testing for all polymer materials in contact with the ointment.

● The LF-90 is designed for a cold filling process, avoids voids due to shrinkage of the ointment.
