The Brown 50mm Heat Shrinkable Tube (25M/Roll) is engineered for maximum insulation and protection of large-diameter cables and components in industrial and electrical systems. With a 2:1 shrink ratio, it shrinks to half its original diameter when heated, forming a tight, durable seal that resists abrasion, chemicals, and moisture.

Key Features

• Inner Diameter (Before Shrink): 50mm
• Inner Diameter (After Shrink): ≤ 25mm
• Wall Thickness (After Shrink): Approx. 0.6mm
• Shrink Ratio: 2:1
• Color: Brown
• Length: 25 meters per roll
• Material: Flame-retardant polyolefin
• Operating Temperature: -55°C to +135°C
• Shrink Temperature: Begins at 90°C
• Voltage Rating: 1KV
• Certifications: UL 224 VW-1, MIL-I-23053/5 Class 1 & 3, RoHS Compliant
• Dielectric Strength: ≥19.7 kV/mm
• Resistant To: Common fluids, solvents, and fungus (tested to ASTM standards)

Applications

• Insulation and bundling of large power cables
• Mechanical protection in control panels and switchgear
• Color-coded identification in electrical systems
• Automotive, marine, and heavy machinery wiring

This tubing is ideal for professionals who need robust, high-dielectric-strength insulation in demanding environments.
