Flexible PVDF Heat Shrink Tube Flame Retardant Wear Resistant Tubing for Wire Harness

Flexible, Flame-Retardant PVDF Heat Shrink Tubing

Heat-sensitive electronic and automotive assemblies need insulation that is flexible, tough and fire-safe. This flexible PVDF heat shrink tubing is made from modified polyvinylidene fluoride and is designed for long-term use at high temperatures. It is wear-resistant, cut-resistant and resistant to most oils and chemicals, making it a dependable protective sleeve for the most demanding harnesses, terminals and connection lines.

Where It Performs Best

The tubing is widely used for protecting welding points, terminals and connection lines exposed to high temperature, industrial fuels, solvents and chemical reagents. Because it holds its shape and color reliably, it also serves as an excellent identification tube in complex wiring systems, helping engineers trace and mark circuits quickly. Its soft shrinkage conforms neatly to irregular shapes without cracking or splitting.

Technical Specifications

Reliability You Can Trust

• High flame retardancy with a soft, flexible fit
• Thermal aging tested at 175°C for 168 hours retaining at least 250% elongation
• Thermal shock at 275°C for 4 hours with no cracking
• Cold bend at -30°C for 1 hour with no cracking
• Volume resistivity of at least 10¹⁴ Ω·cm

Why Flexible PVDF Pays Off

Rigid sleeving can stress delicate joints and crack under vibration. The flexible grade of PVDF used here bends with the harness while still delivering high dielectric strength and thermal endurance, reducing the risk of field failures and rework. For designers balancing thermal performance with installation ease, it offers an excellent middle ground between standard polyolefin and fully rigid high-temperature sleeves.

Colors, Storage and Supply

Standard colors are black and transparent, with other colors available on request. Store the tubing at -10°C to 40°C and relative humidity below 75%; shelf life exceeds five years. Manufactured by XingQi in Shenzhen, Guangdong, China, the product ships within 3–5 work days on T/T terms, with carton packaging that can be customized for your market.

Easy Handling and Long Shelf Life
