The steel - plastic composite belt consists of a metal layer and a copolymer film on one or both sides of the composite.Different base and coating materials have great influence on the properties of the steel - plastic composite belt.In the communication industry standard revised in 2007, the steel - plastic composite belt has made a new regulation.Base material selection in the past domestic manufacturers in the production of steel-plastic composite belt, the general base belt with chromium plating, tin plating or no coating steel belt.In the new standard, the tin-plated steel strip and its requirements are deleted, and all the chrome-plated steel strip is required as the base band.
