Heat-Shrinkable Silicone Rubber Tubing

CB-SRT

Applications

Our heat-shrinkable silicone rubber tubing is specifically designed to insulate, protect, and coat electronic components with special requirements. It is widely used in the electronic, lighting, and medical equipment industries. Its key advantage over other tubing is its ability to withstand temperatures up to 200°C.
