PTFE-Copper Powder Composite Tube Product Introduction

Product Overview

PTFE-Copper Powder Composite Tube is an innovative composite pipe material made from Polytetrafluoroethylene (PTFE) and high-purity copper powder. It combines the exceptional chemical inertness of PTFE with the excellent thermal/electrical conductivity of copper, making it an ideal solution for tackling challenges of corrosion protection and thermal management in special operating conditions.

Core Advantages

· Dual Functionality: Thermal conductivity up to 5-8 W/m·K (20 times higher than pure PTFE), while maintaining excellent corrosion resistance.

· Safe & Anti-static: Volume resistivity of 10²-10⁴ Ω·cm, effectively eliminating electrostatic hazards.

· Stable Over Wide Temperature Range: Reliable long-term operation from -100°C to +200°C.

· Long Service Life: Corrosion-resistant lifespan is 3-5 times that of metal pipes.

Through innovative material composite technology, PTFE-Copper Powder Composite Tube successfully solves the industry challenge where traditional materials cannot balance both corrosion resistance and thermal conductivity. We provide professional technical support and customization services.
