PTFE Tape is made of heavy PTFE coated fiberglass, single sided or double sided coated with high temperature resistant silicone adhesive (No residual glue）.It can resistance 300 degrees. This premium tape which has a heavier PTFE coated can provide a smoother surface with enhanced durability compared to other PTFE silicone adhesive tape. Due to its well know PTFE properties, the excellent strength and dimensional stability of the fiberglass, and a high temperature range of the adhesive system results in a roduct appropriate for use in a variety of high temperature demanding applications. Yellow rippled release liner or dot dimple PVC release liner is applied to the adhesive surface for ease of application. Widely use for packaging (heat sealing, shrink wrapping) as a heat resistant release surface placed over heating elements and pressure bars,the tape maintains durability at high speeds and high temperatures.

Teflon tape, also known as PTFE tape (polytetrafluoroethylene tape), is a type of sealing tape made from a thin film of PTFE material. It is commonly used for its non-stick and lubricating properties in plumbing and pipe fitting applications. Here are some key features and common uses of Teflon tape:
　　
Features:
1. Non-Stick Properties: Teflon tape has excellent non-stick characteristics, which prevent adhesion and make it easy to remove after application.
2. Lubrication: The tape provides a lubricating effect, allowing for smoother assembly and disassembly of threaded connections, reducing friction and the risk of galling or seizing.
3. Chemical Resistance: Teflon tape is highly resistant to many chemicals, solvents, and acids, making it suitable for various plumbing applications where resistance to corrosive substances is required.
4. Temperature Resistance: PTFE tape exhibits good temperature resistance, withstanding a wide range of temperatures without degradation or melting. It can typically handle temperatures ranging from -200°C (-328°F) to 260°C (500°F) or higher, depending on the specific product.
　　
Common Uses:
1. Pipe Thread Sealing: Teflon tape is primarily used for sealing pipe threads in plumbing applications. It is wrapped around the threaded ends of pipes and fittings to create a tight seal and prevent leaks. The tape fills gaps and provides a barrier to prevent the escape of liquids or gases.
2. Plumbing Connections: It is commonly used in various plumbing connections, such as faucets, showerheads, valves, and other threaded fittings, to ensure a secure and leak-free connection.
3. Gas Lines: Teflon tape is often used in gas piping systems to provide a reliable seal and prevent gas leaks. However, it's important to use the appropriate type of Teflon tape specifically designed for gas applications.
4. Water Filtration Systems: The tape can be used in water filtration systems, such as under-sink filters or whole-house water filters, to create watertight connections and prevent leaks.
　　
It's important to note that Teflon tape is not suitable for all applications. It is typically used for tapered pipe threads and should not be used on straight threads. Additionally, it is not recommended for use in applications that involve high-pressure hydraulic systems.
　　
When using Teflon tape, it's crucial to apply it correctly by wrapping it tightly around the thread in the direction of the thread rotation. This ensures a proper seal and prevents the tape from unraveling during installation.
　　
Always follow the manufacturer's instructions and consult with a professional if you have specific concerns or questions regarding the use of Teflon tape in your particular application.
