VOLSUN
The 2:1 UV EPDM Heat Shrink Tube represents a specialized solution for electrical insulation and environmental protection in demanding outdoor applications. Crafted from ethylene propylene diene monomer (EPDM) rubber, this heat shrinkable tubing combines exceptional UV resistance with broad chemical compatibility, making it ideal for protecting wires, cables, and components exposed to harsh environmental conditions. Its 2:1 shrink ratio provides versatile coverage for irregular shapes and multiple conductor configurations, while its temperature resistance ensures reliable performance in extreme thermal environments.
Formulated with UV-stabilized EPDM rubber, the tube provides long-term resistance to ultraviolet radiation, ozone, and weathering—eliminating the cracking and degradation common in standard PVC heat shrink products. It exhibits excellent resistance to acids, alkalis, and chemical solvents, maintaining integrity in industrial and agricultural environments . The material's flexibility ensures reliable performance even at low temperatures.
Designed for continuous operation from -45°C to 125°C, the heat shrink tube withstands extreme temperature fluctuations without losing insulating properties . It begins shrinking at 100°C and achieves full recovery at 135°C, allowing installation with standard heat guns or ovens . The tube maintains dimensional stability under prolonged heat exposure, preventing loosening or cracking in high-temperature applications.
With a 2:1 shrink ratio, the tube easily conforms to irregular shapes, connectors, and splices, providing a tight, uniform seal . Its free expansion design allows easy positioning before heating, reducing installation errors. The black opaque formulation provides excellent light blocking and UV protection for sensitive components contained within.

Protects exposed wire harnesses, splices, and connections in outdoor lighting, irrigation systems, and landscape electrical installations. Its UV resistance prevents degradation in direct sunlight applications.
Insulates and protects cable connections in solar panel arrays, wind turbine nacelles, and battery storage systems. Withstands the temperature extremes and weather exposure typical of renewable energy installations.
Shields underhood wiring, battery cables, and sensor connections from engine heat, oils, and road debris. Suitable for both on-road vehicles and off-highway equipment operating in harsh conditions.
Provides abrasion and chemical resistance for cables and hoses in manufacturing environments, food processing facilities, and agricultural equipment. Its flexibility accommodates vibration and movement in dynamic machinery.
EPDM offers superior UV resistance and ozone stability compared to standard PVC heat shrink tubing, providing 5-10 times longer service life in outdoor environments . It maintains flexibility at lower temperatures and resists cracking from repeated thermal cycling, making it ideal for exposed applications.
The tube can be installed with standard hot air guns (300-500°C) or industrial ovens. For best results, use a heat gun with variable temperature control to reach the 100°C minimum shrink temperature without exceeding 200°C, which could damage the material .
Yes, when properly installed, the EPDM heat shrink tube provides a watertight seal suitable for direct burial. Its chemical resistance protects against soil contaminants, while the 2:1 shrink ratio ensures a tight seal around cables that prevents water ingress and corrosion.
The tubing is available in expanded inner diameters from 6 mm to 100 mm, covering finished diameters from 3 mm to 50 mm after shrinking. This range accommodates everything from small gauge wires to multi-conductor cables, with standard lengths of 1 meter and 5 meters available for most sizes.

Remark：Special sizes & packing are available on request
Q1: Are EPDM heat shrink tubes reusable?
No, heat shrink tubes are not design to reusable. Once heating, it shrinks to form a protective layer, and cannot take down and use again.
Q2: What temperature range of EPDM heat shrink tubes?
Excellent high temperature resistant, can be used for a long time in an environment of 150 ° C, and also can be used for a short time or intermittently in an environment above 180-200 ° C.
Q3: Is it possible to get free samples first?
Yes, we provide free samples of EPDM heat shrink tubes so that you can test first.
Q4: What is the delivery time?
For regular sizes that in stock, we will send the goods within 3~5 days, mainly depending on the quantity.
Q5: What's the MOQ for EPDM rubber heat shrink tubes?
For most sizes available in stock, there is no MOQ request, one roll is OK.
