Teflon tapes, also known as PTFE (polytetrafluoroethylene) tapes, are highly valued for their non-stick properties and chemical resistance. These tapes are commonly used in plumbing applications to seal pipe threads, preventing leaks and ensuring a tight fit. They can withstand high temperatures and harsh chemicals, making them suitable for use in various industrial settings, including chemical processing and electrical insulation. Teflon tapes are also used as a release surface in heat sealing and packaging operations due to their ability to resist sticking to other materials. Their versatility and durability make them an essential tool in many industries.
