The advent of 5G networks has had a significant impact on these critical components, particularly the connectors and cables used in the wireless and wired infrastructures. Recently, the united states and the united kingdom have announced an acceleration in 5G network development, which has injected energy into the entire network industry. Today, western economies are trying to compete with the 5G technology that china has focused on, yet achieving this leap on a large scale will depend on the adoption of new cable technology.
The PVC (polyvinyl chloride) cable has insufficient flame resistance due to the incorporation of a large amount of plasticizer and other auxiliary agents, and can generate HCl gas harmful to human bodies during combustion, and the HCl gas also has a strong corrosive effect on metals. Besides generating toxic gases, a large amount of smoke is generated due to incomplete combustion of some gases, and the life and property safety of people are seriously affected. When the cable is laid in the north, the cable needs to have certain cold resistance and certain ultraviolet-proof aging performance to ensure the safe use of the cable. Therefore, the researched and developed PVC cable material with temperature resistance, flame retardance, cold resistance, environmental protection and ultraviolet resistance has important social value.
