In harsh environments such as municipal pipelines, chemical equipment, and outdoor communications, joint protection has always been a weak link in the safe operation of equipment. Traditional heat shrink tubing relies on heating tools, making installation inconvenient. It is also prone to aging, cracking, and even failure under complex conditions such as acid and alkali corrosion, prolonged exposure to sunlight, or freezing. Volsun EPDM cold shrink tubing, with its excellent material properties and convenient cold shrink technology, redefines the standard for joint protection, becoming a weatherproof and corrosion-resistant guardian for all types of connection points.
Volsun EPDM cold shrink tubing, made of EPDM rubber, offers excellent weather and corrosion resistance. In ozone resistance testing, it remained crack-free for 168 hours at 40°C; after immersion in a 5% hydrochloric acid and 10% sodium hydroxide solution for 24 hours, it showed no surface corrosion; and after a 480-hour salt spray test, it remained rust-free. Whether in coastal high-salt environments or in the acidic and alkaline media of chemical plants, it can easily withstand these conditions.
The EPDM cold shrink tube also offers stable performance in a wide operating temperature range, from -40°C to 120°C. Even during installation in the bitter cold of northern China, the tubing remains crack-free. After high-temperature thermal aging, the tensile strength retention exceeds 80%, ensuring long-term durability.
During installation, simply remove the support strips for automatic shrinkage, eliminating the need for heating tools or hot melt adhesive. This increases installation efficiency by 60% compared to traditional heat shrink tubing, making it easily completed by one person.
In addition, EPDM cold shrink tubing offers high mechanical strength and a long service life. Its tensile strength is no less than 8.0 MPa, its elongation at break exceeds 600%, and its tear strength exceeds 25 kN/m. These excellent mechanical properties allow it to withstand the strain of construction, soil compression, and even external punctures, making it suitable for long-term burial or outdoor exposure, effectively extending the lifespan of joints.
Furthermore, Volsun EPDM cold shrink tubing offers a comprehensive range of specifications and custom lengths to meet diverse needs. Our products comply with GB/T 19666-2015 standards and have passed RoHS environmental testing. They are widely used in numerous municipal and chemical projects.
