Fluoramics introduces PFAS-Free Poly-U Thread Tape
For decades, PTFE thread tape, otherwise known by the brand name Teflon, has been a common choice for sealing threaded pipe connections. As more industries look for al-ternatives to fluoropolymer-based materials, Fluoramics is introducing Poly-U Thread Tape, a polyurethane-based, PTFE- and PFAS-free option designed to provide reliable thread sealing without fluoropolymers.
What is Poly-U Thread Tape?
Poly-U is a polyurethane-based PTFE-free plumbers tape designed as an alternative to traditional PTFE thread tape.
Made from durable polyether polyurethane, Poly-U combines strength and flexibility to conform to threaded surfaces and create tight, leak-resistant connections.
The tape is safe for use with both metal and plastic fittings and is designed for residential, commercial, industri-al, and maintenance applications.
Why was Poly-U developed?
Poly-U was developed in response to growing demand for high-performance sealing products that eliminate PTFE and PFAS.
The goal was to provide professionals with another thread-sealing option without giving up the durability, flex-ibility, chemical compatibility, and ease of installation they expect from thread seal tape.
Because Poly-U is completely PTFE- and PFAS-free, it provides an option for applications where fluoropolymer-based materials are not preferred or required to be avoided.
How is Poly-U different from traditional PTFE thread tape?
The main difference is the material.
Traditional thread tape is commonly made from PTFE, while Poly-U is made from polyether polyurethane. This gives professionals another material option when selecting a thread sealant.
Poly-U is designed to provide the flexibility needed to conform to threaded surfaces while maintaining the strength and durability needed for reliable sealing.
What can Poly-U be used with?
Poly-U is designed for use with water, oxygen, gases, oils, and a broad range of chemicals and acids. Its chemical compatibility includes applications involving:
- Oxygen
- Anhydrous ammonia
- Antifreeze
- Hydrogen peroxide
- Mineral and motor oils
- Acids
- Natural gas
- Nitrogen
- Argon
- Hydrogen
- Propane
- Other commonly used industrial fluids and gases
For specific chemical compatibility requirements, users should consult the Poly-U technical data sheet.
Is Poly-U suitable for oxygen service?
Poly-U has been oxygen-tested under ASTM G72 at both 1,500 psi and 6,000 psi. This testing supports its use in demanding oxygen-service applications where an appropriate thread sealing material is required.
What standards and certifications does Poly-U meet?
Poly-U Thread Tape uses materials compliant with FDA 175.105 and FDA 175.320 for food-contact applications.
The polyurethane material also meets USP Class VI and ISO 10993 standards. Its service temperature range is -30°C to +135°C (-22°F to +275°F).
Users should review application-specific requirements and the applicable technical documentation before select-ing the product for a particular service.
Where can Poly-U be used?
Poly-U pipe tape can be used to seal threaded connections across a wide range of applications, including:
- Plumbing and piping
- Air compressors
- Compressed gas valves and tanks
- Natural gas systems
- Oxygen systems
- Water and wastewater systems
- Industrial equipment
- Maintenance applications
- Residential and commercial installations
Its compatibility with both metal and plastic fittings also makes it suitable for a variety of threaded con-nection types.
What makes Poly-U different from a typical thread-sealing tape?
Poly-U brings a polyurethane-based material to a product category traditionally dominated by PTFE.
The tape is designed to be flexible, durable, and water resistant while providing a tight seal on threaded connections.
It also gives users an option for applications where a PTFE- and PFAS-free sealing material is desired.
Made in the USA, Poly-U Thread Tape has received U.S. Patent No. 12,624,778 B1, recognizing the innovation behind its design. The product is part of Fluoramics' broader portfolio of specialized thread sealants and tapes. It is available in ¼-inch, ½-inch, and ¾-inch widths.
