Thickness Variations
Our PTFE film is produced by extrusion or compression molding of PTFE resin, followed by a process called skiving, which slices the solid PTFE block into thin film. The thickness of PTFE film can vary depending on the specific application. Here are some thicknesses ranges and their applications.
Thin PTFE Film (0.005 - 0.025 mm)
Thin PTFE films are often used as release liners for adhesive-backed materials, such as tapes or labels, or employed as heat-sealing surfaces for packaging applications.
Medium PTFE Film (0.025 - 0.1 mm)
PTFE films in this thickness range are commonly used as electrical insulation for wiring, cables, and circuit boards. They offer excellent dielectric properties and heat resistance.
Thick PTFE Film (0.1 - 0.5 mm and above)
Thick PTFE films are the most rigid among the three options. They are less conformable compared to thinner films and are commonly used as a lining material for tanks, pipes and vessels.

FAQs of PTFE Film
How is your PTFE film manufactured?
Our PTFE film is typically manufactured through a process called paste extrusion or skiving. In paste extrusion, PTFE resin is mixed with lubricants and then extruded into a thin film. In skiving, PTFE resin is extruded into a sheet, and then thin layers are shaved off to achieve the desired film thickness.
What are the available thicknesses of your PTFE film?
PTFE film comes in various thicknesses, ranging from very thin films (e.g., 0.005 mm) to thicker sheets (e.g., 0.5 mm), depending on the application requirements.
How to choose the correct thickness of your PTFE film?
If tear resistance is important, you should consider choosing thicker PTFE films or laminates with reinforcing layers. For abrasion resistance, explore composites with fillers like glass fiber or other polymers.
Do you have stock samples? And how to get them?
Yes, we have a large inventory of PTFE film in our warehouse. Free samples only take 5~7 days leading time for a quick quality check.
What are your payment terms?
- For sample orders, Paypal or T/T 100% as a deposit.
- For bulk orders, we request 30% by T/T in advance, the balance to be paid before shipment.
