Our PTFE belting is specifically engineered to maximize conveyor belt life, while minimizing down time in the most demanding belting environments. These fabrics are manufactured from PTFE coated woven fiberglass. These belts provide an extremely smooth, non-stick surface, excellent release and resist oils, grease and chemicals. Our proprietary coatings were developed to prevent wicking of oils and greases into the belt carcass, while offering superior durability. These fabrics are excellent for use in the most challenging applications, such as high temperature grill belts and press belts. They provide unmatched product release for sticky or gummy products.
PTFE Chemical Resistance
PTFE is a desired material for many applications because of near-perfect chemical resistance properties, severe temperature stability, and non-stick capability. PTFE, however, is generally weak and requires a reinforcement material. Fiberglass is a common reinforcement used with PTFE since it is a cost-effective material with high temperature capability. PTFE is usually applied to fiberglass using a dip-coating process. Dip-coated PTFE materials have been used for years in many different applications including food processing and conveyor belting.
To improve the performance of dip-coated materials, PTFE films are laminated to PTFE dip-coated surfaces.
A PTFE film laminate consists of PTFE films that have been laminated to a PTFE coated fiberglass fabric. While some PTFE coated products can perform adequately in the demanding conditions, overwhelming evidence has shown that a PTFE film laminate provides the best long-term protection for the fiberglass reinforcement.
Surface cracks in PTFE coatings permit harmful fluids to penetrate into the fiberglass substrates. These cracks are totally unavoidable in any PTFE coated fiberglass fabric. When a PTFE film is laminated to a PTFE coated surface, the surface cracks remain sealed for the life of the product.
PTFE Film Permeation Properties
The overall porosity and permeation properties in PTFE film laminates will be lower than those found in PTFE coated fiberglass fabrics. Additionally, the laminated PTFE film ensures that the composite maintains a uniform PTFE thickness over the entire surface. The tough PTFE film barrier makes cleaning easier and eliminates any concern for the thin coating area found in all PTFE coated fiberglass fabrics.

PTFE Belting: An Overview
PTFE (Polytetrafluoroethylene) belting is a versatile material known for its exceptional non-stick properties, high-temperature resistance, and chemical inertness. These belts are widely used in various industries, including food processing, textiles, automotive, and electronics, due to their superior performance and durability.
Advantages of PTFE Belting:
Non-Stick Properties: PTFE belting prevents materials from sticking, making it ideal for applications where cleanliness and ease of release are critical.
- High-Temperature Resistance: PTFE belts can withstand temperatures up to 260°C (500°F), making them suitable for high-heat processes.
- Chemical Resistance: PTFE is resistant to most chemicals, including acids, bases, and solvents, ensuring longevity and reliability in harsh environments.
- Low Friction: The low friction coefficient of PTFE reduces wear and tear on machinery and extends the life of the belts.
- Dimensional Stability: PTFE belts maintain their shape and size even under extreme conditions, ensuring consistent performance.
Applications of PTFE Belting
Food Processing: PTFE belts are used in the production of baked goods, snacks, and other food items where non-stick properties are essential. They are also used in contact cooking applications, such as grilling meats and producing flatbreads.
Textiles: In the textile industry, PTFE belts are used for thermal bonding, laminating, and drying processes. They help bond layers of fabric together without sticking and allow for efficient heat transfer.
Automotive: PTFE belts are used in the automotive industry for applications such as coating, laminating, and heat sealing. Their resistance to oils and greases makes them ideal for these processes.
Electronics: PTFE belts are used in the electronics industry for the production of printed circuit boards (PCBs) and other components. Their non-stick properties and high-temperature resistance ensure clean and precise manufacturing.
Packaging: PTFE belts are used in the packaging industry for processes such as coating, laminating, and converting. They provide a non-stick surface that prevents adhesion and ensures high-quality packaging.
Types of PTFE Belting
Closed-Woven Belting: These belts are made from woven fiberglass or Kevlar fabrics coated with PTFE. They offer excellent release properties, durability, and dimensional stability.
Open-Mesh Belting: Open-mesh PTFE belts have a mesh-like structure that allows for better airflow and heat transfer. They are used in applications such as drying and curing processes.
Heavy-Weight Belting: These belts are thicker and heavier, providing additional strength and durability for demanding applications.
Multi-Ply Belting: Multi-ply PTFE belts consist of multiple layers of PTFE-coated fabrics, offering enhanced mechanical properties and preventing creasing in double belt press laminators.
Conclusion
PTFE belting is a versatile and reliable material that offers numerous advantages for various industrial applications. Its non-stick properties, high-temperature resistance, and chemical inertness make it an excellent choice for industries requiring high performance and durability. Whether it’s food processing, textiles, automotive, electronics, or packaging, PTFE belting provides consistent and efficient results.
