Product Brief
PTFE Dispersion-Coated Fiberglass Fabric: Exceptional High-Temp Resistance (-60℃~300℃), Non-Stick & Corrosion-Proof. Ideal for Industrial Insulation, Conveyor Belts & Sealing. Durable & Cost-Effective.
Product Overview
PTFE dispersion-coated fiberglass fabric is a high-performance composite material formed by uniformly coating aqueous polytetrafluoroethylene (PTFE) dispersion onto high-strength fiberglass fabric substrates. As a synergistic combination of two premium materials, it integrates the excellent tensile strength and dimensional stability of fiberglass with the superior chemical inertness, non-stick property, and thermal resistance of PTFE-a core perfluoropolymer. Unlike standalone FEP sheets or PVDF tubing, this coated fabric is a flexible, adaptable material designed to solve extreme environment challenges in industrial processes, serving as a critical component in insulation, conveying, and sealing applications.
Product Details
Our PTFE dispersion-coated fiberglass fabric is engineered to deliver unmatched performance in harsh industrial environments, leveraging the precise formulation of our PTFE dispersion (model HD903) and high-quality fiberglass substrates. The PTFE dispersion used for coating is a stable aqueous emulsion with a 60% solid content, 4-7 wt% surfactant concentration, and a pH range of 9-10.5, featuring ultrafine particles (average size 0.15μm-0.35μm) that ensure uniform penetration and adhesion to fiberglass fibers. This formulation is critical for forming a seamless, pinhole-free coating: the fine particle size allows complete coverage of individual fiberglass filaments, while the balanced surfactant system ensures dispersion stability during the coating process without compromising the final material's integrity.
A defining feature of this composite material is its exceptional thermal resistance, a result of the synergistic properties of PTFE and fiberglass. The PTFE coating retains its stability at continuous operating temperatures of -60℃ to 300℃ and can withstand short-term peaks up to 320℃-far exceeding the performance of conventional coated fabrics. This is rooted in PTFE's fully fluorinated molecular structure, which provides strong intermolecular bonds that resist thermal degradation, while the fiberglass substrate maintains dimensional stability even at extreme temperatures (elongation coefficient ≤5%). For industrial users, this means reliable performance in applications such as high-temperature oven insulation, heat-sealing equipment components, and exhaust system gaskets, where temperature fluctuations and extreme heat are common.
Superior non-stick and chemical resistance are another core advantage. The PTFE coating imparts an extremely low surface tension (the lowest among solid materials), ensuring no adhesion to any substance-from sticky industrial adhesives to corrosive chemicals. This makes the fabric ideal for use as conveyor belts in food processing (e.g., baking, freezing) and plastic molding industries, where product buildup and contamination are major concerns. Additionally, the coating is inert to nearly all acids, alkalis, salts, and organic solvents, while the fiberglass substrate resists chemical erosion, making the composite suitable for chemical processing facilities, where it can be used as tank liners, valve seals, and protective curtains. Unlike uncoated fiberglass, which is susceptible to chemical damage, our PTFE dispersion-coated fabric maintains its properties even after prolonged exposure to aggressive media.
Versatility and durability further distinguish this product. It offers excellent mechanical toughness, with a tensile strength of ≥300 N/50mm (warp) and ≥280 N/50mm (weft), ensuring resistance to tearing and abrasion in high-wear applications. The fabric is also flexible and easy to cut, sew, and install, adapting to complex shapes such as curved seals and irregularly sized insulation wraps. It integrates seamlessly with other perfluoropolymer products: for example, it can be paired with PVDF tubing in chemical fluid handling systems to create a fully corrosion-resistant setup, or used alongside FEP sheets in high-temperature insulation assemblies. Beyond industrial applications, it is also suitable for aerospace (engine compartment insulation) and electronics (high-temperature wire wrapping) sectors, where reliability and performance are paramount.
Reliability is guaranteed through strict manufacturing and quality control processes. Our coating process involves dip-coating the fiberglass fabric in PTFE dispersion, followed by drying at 120℃ to remove moisture and sintering at 380℃ to form a strong, bonded coating. Each batch is tested for coating uniformity, thermal resistance, tensile strength, and chemical resistance, with detailed test reports available upon request. Real-world case studies validate its performance: a leading food processing plant reduced conveyor belt cleaning time by 70% after switching to our PTFE dispersion-coated fiberglass fabric, while a chemical manufacturer reported a 50% extension in seal lifespan compared to conventional materials. These results demonstrate the product's ability to solve practical industrial problems-reducing maintenance costs, improving operational efficiency, and minimizing downtime.

FAQ (Frequently Asked Questions)
Q1: What are the main applications of PTFE dispersion-coated fiberglass fabric?
A1: It is widely used in high-temperature insulation (oven, exhaust systems), conveyor belts (food processing, plastic molding), sealing components (valves, gaskets), protective curtains (chemical plants), and aerospace/electronics insulation. Its versatility makes it suitable for any scenario requiring heat resistance, non-stick, or corrosion protection.
Q2: How should this coated fabric be stored to maintain its performance?
A2: Store in a dry, well-ventilated environment at 10-30℃, avoiding direct sunlight and moisture. Do not fold it under heavy loads to prevent permanent creases. The shelf life of the finished fabric is 1 year when stored properly; the PTFE dispersion raw material has a 6-month shelf life from production.
Q3: Can the fabric be customized to specific sizes or thicknesses?
A3: Yes. We offer custom cutting to any width (up to 2m) and length, and can adjust the PTFE coating thickness (0.1mm-0.5mm) according to your needs. We also provide custom sewing services for shaped components such as seals and wraps.
Q4: Is this product suitable for food contact applications?
A4: Yes. Our PTFE dispersion meets FDA 21 CFR 177.1550 and EU 10/2011 food contact standards, making the coated fabric safe for use in food processing conveyor belts, baking mats, and other food-contact components.
Q5: What is the maximum processing temperature for the coated fabric?
A5: The fabric can be used continuously at -60℃~300℃ and withstand short-term peaks up to 320℃. Avoid exposure to temperatures above 420℃, as this may cause PTFE degradation and toxic gas release.
