Reliable Pipeline Sealing Since 2009
For over 16 years, ForeverSeal has been deeply committed to the research and manufacturing of PTFE thread sealing tape (commonly known as "raw material tape"), providing reliable, leak-free sealing solutions for global gas, water, chemical, and industrial pipeline systems. Our products are widely used in:
- Natural gas and liquefied gas pipelines (yellow tape, compliant with EN751-3)
- Drinking water and hot water systems (white/pink tape, WRAS and NSF certified)
- Harsh industrial environments such as chemical plants, pharmaceutical plants, and power plants (resistant to strong acids, strong alkalis, high temperatures, and high pressures)
In recent years, while consolidating our core sealing business, we have strategically expanded into the ePTFE functional film business (SunFilm® brand) based on our accumulated PTFE material technology, serving high-end fields such as 5G cables and medical applications.

Sustainability and Security
In the world of sealing and signaling, reliability is reflected not only in product performance, but also in how we care for the planet, our people, and our partners.
As a manufacturer of PTFE materials, we fully recognize the potential environmental and energy impacts associated with the fluorochemical industry.
That is why ForeverSeal embeds responsible innovation into its corporate DNA — from our factories to our supply chain, from our products to the communities we serve.

Extending PTFE Expertise into Advanced MaterialsSunFilm
In delivering tens of millions of meters of PTFE sealing tape to global gas and water systems, we have accumulated a deep understanding of high-purity PTFE resin processing, precision stretch control, and clean production systems.
Based on this core capability,ForeverSeal launched the independent brand SunFilm® in 2021.This is not diversification, but rather an extension of the boundaries of "material reliability."
We only enter application areas that demand the same long-term stability and zero compromise. Focusing on ePTFE (expanded PTFE) functional films, we serve high-end fields with extremely stringent material performance requirements:electrical insulation, chemical linings, seals and gaskets, medical devices, semiconductors, and industrial coatings.
