RUBLS-SILIC
VOLSUN
The Mastic-Enhanced Silicone Cold Shrink Tube features a built-in mastic layer at one or both ends, offering superior waterproof sealing for telecom connectors and other electrical joints. Made from high-quality silicone rubber, it provides exceptional resistance to UV rays, salt spray, ozone aging, and moisture. With an IP68 waterproof rating and a wide temperature range of -60°C to 200°C, this cold shrink tube ensures reliable, long-lasting protection in harsh environments, all with easy, tool-free installation.
● Mastic Layer for Enhanced Waterproofing: Built-in mastic at one or both ends ensures a superior, long-lasting waterproof seal, providing reliable protection for telecom connectors and electrical joints
● Shrink Ratio up to 4:1: Suitable for a wide range of cable diameters, ensuring compatibility with various sizes.
● Exceptional Moisture and Water Resistance: The mastic-enhanced tube offers excellent long-term resistance to moisture and water, keeping electrical connections safe and dry.
● Superior Weather Resistance: Designed to withstand extreme environmental conditions, including UV radiation, ozone aging, and salt mist corrosion, ensuring stable performance even with prolonged exposure to the sun.
● Easy Installation: The tube’s pre-expanded design allows for tool-free installation, saving time while providing a secure, tight seal.
Properties | Typical Data | Test method |
Shore Hardness | 40±5 | ASTM D 2240 |
Tensile Strength | ≥9.0MPa | ASTM D 421 |
Elongation at Break | ＞800% | ASTM D 421 |
Tear Strength | ≥35kN/m | ASTM D 624 |
Breakdown Strength | ≥20 | ASTM D 149 |
Volume Resistivity | ≥1×1015 | ASTM D 257 |
The Mastic-Enhanced Silicone Cold Shrink Tube starts as a pre-expanded tube placed on a removable core. The sleeve made of silicone rubber surrounds the cable or connector, while the mastic layer is positioned at one or both ends of the tube. This mastic layer provides enhanced waterproof sealing once the tube is applied. The D in the diagram represents the diameter of the tube before it shrinks. The installation involves pulling the tube over the cable or connector, with the tube contracting tightly around it.
Once the core is removed, the tube shrinks and tightly grips the cable or connector, creating a secure seal. The mastic ensures a waterproof, moisture-resistant connection, ideal for telecom and other electrical connectors. The L indicates the length of the tube after it has fully contracted, providing an effective and reliable seal. The design of the cold shrink tube, with its built-in mastic, enhances durability and long-term protection against environmental factors.

Remark：Special sizes & packing are available on request.
Measure the size of the cable connector: Confirm the outer diameter of the connector and ensure that the inner diameter of the cold shrink tubing is slightly larger than the outer diameter of the connector so that it can be fully covered.
Determine environmental requirements: Consider the temperature range, chemical corrosion and UV exposure of the installation environment.
Choose the appropriate voltage level: Ensure that the rated voltage of the cold shrink tubing is higher than the rated voltage of the cable.
Consider physical properties: Select the appropriate shrink ratio and mechanical strength according to the application.
Q1. What makes the mastic-enhanced cold shrink tube different from regular cold shrink tubes?
A: The key difference is the built-in mastic layer at the ends of the tube, which provides enhanced waterproof sealing and improves the tube's ability to resist environmental factors like salt mist, UV rays, and ozone.
Q2. How does the mastic improve the waterproofing?
A: The mastic fills gaps between the connector and the tube, forming a tight, moisture-resistant seal that prevents water from entering the connection, even in harsh environmental conditions.
Q3. Can I use this tube in outdoor applications?
A: Yes, our mastic-enhanced cold shrink tube is UV-resistant and can withstand prolonged outdoor exposure, making it ideal for use in outdoor and harsh environments.
