Shrink ratio is also one of the performance parameters of cold shrink tube.
Shrink ratio also can be called expansion ratio, it refers to the change of inner diameter of prefabricated silicone tube after the main body is expanded, that is, the ratio of inner diameter after expansion to that before expansion.
The shrink ratio can be expressed by a formula like this:
Shrink ratio= Before shrink ID / After shrink ID % .
The greater the expansion rate of silicone tube, the greater the radial pressure generated after shrinkage, so that the interface electrical performance and waterproof sealing performance is better, the insulation protection will be more safe and durable.
Volsun silicone rubber cold shrink tube has a high shrink ratio 5:1, and the shrink ratio of EPDM cold shrink tube is 3.5:1.
Cold shrink tube widely used for waterproof and sealing protection in telecommunication base station.
