Fluoramics launches PFAS-free Poly-U thread tape

Fluoramics has introduced Poly-U Thread Tape, a polyurethane-based alternative to PTFE thread seal tape that is free of PFAS and aimed at plumbing, gas, industrial, and maintenance uses. The product is designed for broad chemical compatibility, oxygen-service applications, and food-contact-related standards.

Why it matters: - Poly-U gives contractors and industrial users a thread-sealing option that avoids PTFE and PFAS. - The launch addresses growing demand for non-fluoropolymer materials in sealing applications. - The product is positioned for use in systems where chemical exposure, pressure, temperature, and material compatibility all matter.

What happened: - Fluoramics introduced Poly-U® Thread Tape, a polyurethane-based thread seal tape. - The product is PTFE-free and PFAS-free. - Fluoramics announced the product from Lewiston, Minnesota, on September 28, 2026. - The company manufactures specialty lubricants, sealants, and high-performance industrial products.

The details: - Poly-U is made from durable polyether polyurethane. - The tape is designed to combine flexibility and strength so it can conform to threaded surfaces and form leak-resistant connections. - Poly-U is suitable for metal and plastic fittings. - Fluoramics designed the tape for residential, commercial, industrial, and maintenance applications. - The product is designed to provide water resistance and broad chemical compatibility. - Poly-U is designed for water, oxygen, gases, oils, and a broad range of chemicals and acids. - Listed uses include oxygen, anhydrous ammonia, antifreeze, hydrogen peroxide, mineral and motor oils, acids, natural gas, nitrogen, argon, hydrogen, propane, and other commonly used industrial fluids and gases. - Users should consult the Poly-U technical data sheet for specific chemical compatibility requirements. - Poly-U has been oxygen-tested under ASTM G72 at 1,500 psi and 6,000 psi. - The tape is available in ¼-inch, ½-inch, and ¾-inch widths. - Fluoramics manufactures Poly-U in the USA. - The polyurethane material complies with FDA 175.105 and FDA 175.320 for applicable food-contact uses. - The material also meets USP Class VI and ISO 10993 standards. - Poly-U has a service temperature range of -30°C to +135°C (-22°F to +275°F). - Poly-U Thread Tape has received U.S. Patent No. 12,624,778 B1.

Between the lines: - The product expands Fluoramics' thread-sealing lineup for buyers weighing temperature, chemical exposure, pressure, and compatibility. - The patent recognition suggests the company is trying to differentiate the design as more than a simple material swap. - Fluoramics also markets LOX-8® specialty thread sealants for more demanding chemical or service conditions. - The release reflects a broader industry shift toward alternatives to fluoropolymer-based materials.

What's next: - Fluoramics is offering free samples, with one sample per person, to professionals who want to evaluate the tape. - Customers can review the product and the company’s sealing lineup at Fluoramics.com. - Users are expected to check application-specific requirements and technical documentation before selecting Poly-U for service.
