Is The Silicone Rubber Heat Shrinkable Tube The Softest Heat Shrinkable Tube?

Silicone rubber heat shrinkable tubing is designed and developed for the insulation and protection of electronic components. When the heat shrinkable sleeve is heated, the inner diameter of the sleeve is quickly shrunk by half, and the protected electronic components are tightly wrapped in the sleeve without being affected by the external environment. The biggest advantage of this unlike other bushings is that the temperature resistance reaches 200 °C. Applications are generally used in medical devices, household appliances, aerospace, military, automotive manufacturing, electronic components, transformers, motors, etc.

Silicone rubber heat shrinkable tube use method:

In the production process, the heat-shrinkable tube is heated to a high-elastic state, a load is applied to expand it, and it is rapidly cooled to maintain the expansion state, so that it enters the glass state, and this state is fixed. When heated, it will return to a high-elastic state, but when the load is gone, it will retract.

Which heat shrinkable tube is the softest?

In terms of materials, the silicone rubber heat shrinkable tube is the softest at the same thickness. But silicone rubber heat-shrink tubing is difficult to make thin, PVC heat-shrink tubing can be very thin, but PVC is hard. PE heat shrink tubing can't be as thin as PVC, but relatively soft.
