Environmentally Friendly V-0 Flame Retardant Dual Wall Tube

Code: N/A

The V-0 Flame Retardant Dual-Wall Heat Shrink Tube is designed for high-performance electrical applications, offering fire safety, flexibility, and environmental compliance. It meets V-0 flame retardancy standards, is halogen-free, and features dual-wall construction for superior electrical insulation and moisture protection.

With resistance to UV, chemicals, abrasion, and extreme temperatures, it provides a secure, waterproof bond and a 3:1 shrink ratio for a tight fit on various cable sizes, making it ideal for power distribution, control systems, and energy transmission.

Description

 

The Halogen-Free Medium Flex Cable and V-0 Flame Retardant Dual-Wall Heat Shrink Tube are designed for high-performance electrical applications that demand fire safety, flexibility, and environmental compliance.

This heat shrink tube meets stringent V-0 flame retardancy standards, offering self-extinguishing properties while being halogen-free, making it safe for enclosed or populated environments. Its dual-wall design combines superior electrical insulation with mechanical protection and a moisture-resistant seal, making it ideal for power distribution, control systems, and energy transmission.

Engineered for both indoor and outdoor use, the heat shrink tube resists UV, chemicals, abrasion, and extreme temperatures. Its inner adhesive layer ensures a strong, waterproof bond to cables and components, while the high 3:1 shrink ratio allows it to conform securely to a wide range of cable sizes. This heat shrink tube is an excellent solution where safety, reliability, and durability are critical.
