>> Product Introduction
EPDM Cold shrink tube is made of EPDM weather-resistant rubber. When in use, you only need to position it and then remove the support tube. The radial pressure is used to form a coating to achieve waterproof and moisture-proof sealing. EPDM cold shrink tube has excellent weather resistance, acid and alkali resistance, and can achieve the function of breathing sealing. It is an ideal sealing material for communication cables and coaxial cables. It is mainly used for moisture-proof sealing at the joints between antennas and feeders and wires in the antenna feeder system of communication base stations.
Material advantages:
Excellent anti-pollution, anti-aging, waterproof, corrosion-resistant, cold-resistant, anti-ultraviolet radiation and other properties.
Material advantages:
It has excellent anti-pollution, anti-aging, waterproof, corrosion-resistant, cold-resistant, anti-ultraviolet radiation and other properties, and can be used in cold, humid, high-altitude, and heavily polluted areas
>> Product Advantage
1. Clean the surface: ensure that there is no oil or impurities on the coated part.
2. Pre-expansion positioning: insert the cold shrink tube and align the position.
3. Extract the support strip: slowly pull out the inner lining core rope and shrink it evenly.
4. Check the sealing: it is qualified if there are no wrinkles or bubbles after shrinkage.
