In the communications, power, and industrial sectors, the joints of various equipment and lines often endure harsh environments such as extreme temperatures, humidity, and corrosion. Traditional sealing methods, such as heat shrink tubing, require heating tools and are difficult to adapt to joints of varying sizes, often resulting in poor sealing or even failure. Volsun silicone rubber cold shrink tubing, with its "specialized silicone rubber + high-efficiency cold shrink design," perfectly solves these problems, becoming the "protection expert" for sealing joints in extreme environments.

High and low temperature resistance, adaptable to various extreme environments

Volsun silicone rubber cold shrink tubing uses a special formula that maintains stable performance in extreme temperatures ranging from -60°C to 200°C. It resists brittleness even in the extreme cold of northern regions and ageing in high-temperature industrial environments. It also offers excellent weather resistance, resisting corrosion from UV rays and salt spray, maintaining long-lasting moisture and water resistance even in humid coastal areas.

High shrinkage ratio, tool-free, and easy installation

Volsun silicone rubber cold shrink tubing boasts a high shrinkage ratio of 4-5 times, adapting to connectors with diameters ranging from 6.0 to 72.0 mm, providing a tight fit without cutting. More importantly, it requires no heat or hot melt adhesive; simply pull the support to automatically shrink, enabling a convenient, "pull-and-seal" installation. This significantly improves installation efficiency and reduces costs, making it particularly suitable for complex environments such as high-altitude and outdoor installations.

Strong resilience, long-lasting seal, and secure connections

Volsun silicone rubber cold shrink tubing offers excellent mechanical strength and is tear and puncture-resistant, effectively resisting mechanical damage during construction and maintenance. Its strong resilience provides sustained radial pressure, ensuring long-term use without loosening, preventing the intrusion of moisture, dust, and other impurities, ensuring the safety and reliability of connections.

Multiple applications, precise protection

Volsun silicone rubber cold shrink tubing is widely used in communications engineering, power cables, cable television, industrial equipment, and other fields, providing precise protection for various connectors. For example, in communication projects, it can be used for sealing optical cable joints and base station cables. It is UV-resistant and tool-free to install, greatly shortening the construction period. In power cables, it can be used for insulation protection of intermediate cable joints. It is resistant to low temperatures and pull-resistant, ensuring power supply safety.
