Introduction to cold shrinkable tubes

The communication cold shrinkable tube uses silicone rubber as raw material, which is pre-expanded on the extractable support tube and contracted by elastic retraction force at room temperature. At the same time, it also has the process of lining cement, which increases the sealing performance of the product, and has the advantages of insulation, sealing, protection, small size, convenient and rapid operation, no special tools, and wide scope of application. Compared with heat-shrinkable products, there is no need for tool heating, and it can be tightly sealed in the case of thermal expansion and contraction, and there will be no gaps due to thermal expansion and contraction.

Product characteristics

1. Easy installation, only manual operation, no need to heat or use special tools, no hot melt adhesive or tape at the joint to strengthen the seal;

2. It is suitable for the connection and sealing of cables of different specifications in a wide range, and can be used for indoor, outdoor, overhead, put into water or buried on power, communication and other cables;

3. Strong resilience, large radial retraction, small permanent deformation, even long-term use of the cable still maintain permanent radial pressure, tight sealing, moisture-proof, waterproof, dustproof performance is excellent;

4. Because EPDM has excellent resilience and "elastic memory", it can "breathe" with the seal, so it can play an excellent sealing effect, and can still maintain a very good sealing effect in the dynamic environment of wind blowing and swinging;

5. Excellent salt spray corrosion resistance, acid and alkali resistance, ozone aging resistance, weather aging resistance and ultraviolet aging resistance;

6. High mechanical strength, good flexibility, excellent physical and mechanical properties of puncture resistance, wear resistance, flex resistance and fatigue resistance.
