Waterproof paste for optical cables is a thixotropic paste like chemical waterproof material designed specifically for optical cables, communication cables, and power cables. It is compounded by advanced technology. Its core function is that when the outer sheath of the cable is damaged and water enters, it can quickly expand when encountering water, forming a gel shaped barrier, effectively preventing the further penetration and spread of water along the longitudinal and radial direction of the cable, thus protecting the optical fiber and electrical conductor from water vapor erosion, ensuring the stability of signal transmission and the service life of the cable.

(1) Main features of the product

1、 Excellent water blocking performance: the contained super absorbent resin can quickly absorb and expand hundreds of times after encountering water, forming a dense gel, blocking the water channel, and has high water blocking efficiency.

2、 Good chemical stability: It is non corrosive to optical fibers, grease, and metal materials (such as copper and aluminum) in optical cables, and has excellent compatibility.

3、 Good thixotropy and paste stability: does not drip at high temperatures, does not solidify at low temperatures, the paste is soft and easy to fill. Under the action of shear force, the viscosity decreases, making it easier for construction; Quickly restore to a paste like state after standing still to prevent sedimentation and separation.

4、 Wide temperature applicability: With excellent high and low temperature performance, it can maintain stable performance in a wide temperature range of -40 ℃ to+70 ℃ and adapt to various harsh environments.

5、 Electrical insulation: The body has a high volume resistivity and good electrical insulation performance.

6、 Environmental Protection and Safety: Non toxic, odorless, non corrosive, and friendly to human health and the environment.
