Description

Teflon high-temperature fabric, also known as PTFE-coated fiberglass cloth, is a high-performance composite material renowned for its exceptional thermal stability, chemical resistance, and non-stick properties. This material, derived from the brand name Teflon (a registered trademark of DuPont), has become indispensable across diverse industrial sectors worldwide. This article provides an in-depth analysis of its specifications, classifications, and applications, targeting global buyers seeking reliable solutions for extreme environments.

1. Core Specifications: Precision-Engineered for Performance
Teflon high-temperature fabric is manufactured by impregnating high-strength fiberglass cloth with a PTFE (polytetrafluoroethylene) suspension emulsion, followed by drying and sintering processes. Key specifications include:
1.1 Thickness Range

Standard Thickness: 0.08mm to 1.2mm, with customization options up to 4.0mm for specialized applications.
Thickness-Specific Applications:0.08–0.25mm: Ultra-thin fabrics for precision applications like electronic insulation, food-grade baking mats, and microwave gaskets.
0.35–0.90mm: Heavy-duty fabrics for industrial conveyor belts, chemical pipeline wraps, and architectural membrane structures.
1.2 Width & Weight
Maximum Width: Up to 4,200mm, accommodating large-scale industrial requirements.
Weight Range: 158g/m² to 1,650g/m², ensuring optimal balance between flexibility and durability.
1.3 Tensile Strength
High-Tensile Models: For example, a 0.40mm-thick fabric with a tensile strength of 820N/50mm (warp/weft) is ideal for high-load conveyor systems in automotive manufacturing.
Industrial-Grade Models: A 0.90mm-thick fabric with 6,300N/50mm tensile strength is used in heavy machinery and construction.
1.4 Temperature Resistance
Continuous Operating Range: -196°C to 360°C, with short-term exposure tolerance up to 400°C.
Thermal Stability: No deformation or weight loss after 200 days at 250°C or 120 hours at 350°C.
1.5 Coating & Surface Treatments
Standard Coating: Double-sided PTFE coating for enhanced chemical resistance.
Specialized Coatings:Anti-Static Coating: Surface resistance ≤10⁹Ω, compliant with ATEX standards for explosive environments.
Breathable Coating: 10–15% porosity for ventilation in textile drying machines.
