Unsintered PTFE TAPE For Cable

Founded in 2009, Foreverseal is one of the world's largest manufacturers of high quality PTFE tape. More than 10 years development, foreverseal has successfully upgraded from the PTFE tape to the manufacturing of high-end ePTFE film industry.

In 2019, we have imported of the world-class precision calender and stretching equipment; And established PTFE film test laboratory; The expert who have engaged in the Fluorine industry more than 30 years led the whole technical team, providing us a strong technical for PTFE film and guide us to the new area of PTFE products in the future!

PTFE is a special material, lets work together to make it in a wider range of uses to fulfill the customers' need and even the requires of the whole social development!

 

The high dimensional stability of our unsintered PTFE TAPE for cable, combined with sophisticated winding technology enables our customers to achieve the best processing conditions and the highest electrical performance in the cable sector.

• It is recommended to use high performance unsintered PTFE TAPE for cable and control cables where voltage resistance is required
• High performance insulation and sheath materials.
• Suitable for applications requiring high temperature and chemical resistance.
• It is suitable for cable wrapping, insulation material in radio frequency coaxial cable and key aviation wire insulation.
• Excellent insulation in several wire and cable structures used in many aerospace projects.

 

Our Unsintered PTFE tape is normally supplied to cable manufacturers. For the cable manufacturers, you know that every component of their cables needs to be of the highest quality to ensure reliable performance. One of the most critical components is the tape used to wrap the cables. Unsintered PTFE tape is one of the most popular tapes used in cable manufacturing, and for a good reason.

Benefits of Unsintered PTFE Tape for Cable
There are several benefits of using unsintered PTFE tape for cable manufacturing, including:
1. High Dielectric Strength: Unsintered PTFE tape has a high dielectric strength, making it an ideal insulator for cables. It also has a low dielectric constant, which means that it does not store electric charges that can result in signal interference or signal attenuation.
2. High Temperature Resistance: Unsintered PTFE tape can withstand high temperatures of up to 260°C without degrading or melting. This makes it suitable for use in high-temperature applications such as in aerospace and defense applications.
3. Chemical Resistance: Unsintered PTFE tape has excellent chemical resistance, making it resistant to most chemicals, acids, and solvents. It is also water-resistant, which makes it ideal for use in outdoor or underwater applications.
4. Flexibility and Conformability: Unsintered PTFE tape is highly flexible and can easily conform to the shape of the cable, making it easy to wrap around the cable without leaving any gaps.

Unsintered PTFE Tape vs. Sintered PTFE Tape
The main difference between unsintered PTFE tape and sintered PTFE tape is the manufacturing process. Unsintered PTFE tape is made by cutting or skiving PTFE semi-finished products, while sintered PTFE tape is made by pressing and sintering PTFE particles. As a result, unsintered PTFE tape is more flexible, conformable, and cost-effective than sintered PTFE tape. However, sintered PTFE tape has a higher density and better mechanical properties than unsintered PTFE tape.
Conclusion
Unsintered PTFE tape is an ideal tape for cable wrapping due to its high dielectric strength, high temperature resistance, chemical resistance, flexibility, and conformability. It is also cost-effective compared to sintered PTFE tape, making it a popular choice in cable manufacturing. However, when choosing PTFE tape, it is important to consider the application requirements to ensure the best performance.
