PTFE-Carbon Fiber Composite Tube Product Introduction

Product Overview

PTFE-Carbon Fiber Composite Tube is a new-generation engineered tubing material manufactured by compounding Polytetrafluoroethylene (PTFE) with high-performance carbon fibers. Through a unique composite process, it perfectly combines the chemical inertness of PTFE with the mechanical strength of carbon fiber, offering a high-end tubing solution specifically designed for extreme operating conditions.

Core Advantages

· Ultra-High Strength: Tensile strength reaches 80-120 MPa, 4-6 times that of pure PTFE tubes.

· Exceptional Corrosion Resistance: Withstands all highly corrosive media, including aqua regia and hydrofluoric acid.

· Lightweight Design: Density only 2.0-2.3 g/cm³, 60% lighter than metal tubes.

· Multifunctionality: Adjustable conductivity (10²-10⁶ Ω·cm) and thermal conductivity (5-8 W/m·K).
