About Our PTFE  Fabric Sheet

PTFE high temperature cloth (also called F4 coated fabric) is a high-performance composite, made by impregnating high-quality alkali-free glass fiber cloth with PTFE dispersion emulsion, then drying, baking, sintering and polishing. It combines glass fiber's high temperature resistance and tensile strength with PTFE's excellent non-stick, corrosion resistance and insulation, serving as a core industrial material trusted by global buyers.
It boasts excellent comprehensive performance: continuous service temperature ranges from -70°C to 260°C (short-term up to 300°C) without deformation. With elongation below 5‰, it maintains good dimensional stability. Its low friction coefficient (0.05-0.1) enables oil-free self-lubrication and easy cleaning of attachments, reducing maintenance costs. It resists strong acids, alkalis and organic solvents, and has excellent electrical insulation (dielectric constant <2.6, dielectric loss tangent <0.0025) to meet high industrial standards.
Widely used across industries: petrochemical and power (flue gas desulfurization, pipeline anti-corrosion/sealing), electronics (high-temperature component insulation), food processing (non-stick conveyors, baking pads), textile printing (heat transfer), metallurgy (high-temperature shielding) and aerospace. It adapts to harsh working conditions, providing reliable solutions.
Flexible customization is available to meet personalized needs, including thickness (0.1mm-1.5mm), width (100mm-3000mm), color, surface treatment (polished/matte) and cutting size. We support OEM/ODM, adjust parameters for specific scenarios, and offer small-batch trials and bulk supply. Strict quality control and stable production ensure consistent performance and on-time delivery, lowering your procurement risks.

FAQ

Q1:What is PTFE high-temperature cloth, and what is its core composition?

A1:PTFE high-temperature cloth (also known as PTFE cloth or PTFE Conveyer belt) is a high-performance composite material, mainly composed of PTFE (polytetrafluoroethylene) resin coated or impregnated on a base fabric (usually glass fiber, aramid fiber, or polyester fiber). It combines the excellent properties of PTFE and the mechanical strength of the base fabric.

Q2:What is the maximum continuous operating temperature of PTFE conveyer belt?

Q2:The standard PTFE high-temperature cloth can be used continuously at 260°C, and can withstand short-term high temperatures up to 300–320°C without obvious performance degradation. The heat resistance varies slightly according to the base fabric (glass fiber base has better high-temperature resistance than polyester base).

Q3: What are the key properties of PTFE high-temperature cloth?

A3: Its core properties include excellent high-temperature resistance, non-stick performance (no adhesion to most materials), good chemical resistance (resistant to acids, alkalis, solvents, and oxidants), low friction coefficient, good mechanical strength, and excellent electrical insulation.

Q4: What are the common base fabrics for PTFE high-temperature cloth, and how to choose them?

A4: Common base fabrics include glass fiber (high temperature resistance, high strength, low cost, suitable for most high-temperature scenarios), aramid fiber (excellent tear resistance and flame retardancy, suitable for high-strength and flame-retardant requirements), and polyester fiber (low cost, good flexibility, suitable for low-temperature to medium-temperature scenarios below 150°C). The choice depends on the operating temperature, mechanical strength, and cost budget.
