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.
