Products

As a dedicated joint sealant tape PTFE supplier, we focus on sealing solutions that perform under aggressive chemical, thermal, and mechanical conditions across chemical processing, pharmaceutical, food and beverage, and power generation facilities. Our expanded PTFE joint sealant tape for chemical pipe is produced from 100% virgin PTFE resin using a controlled expansion process that creates a multidirectional fibril structure. This structure gives the tape excellent compressibility and recovery, allowing it to seal irregular, scratched, or worn flange faces without the use of gasket compounds or sealant pastes. For threaded connections and instrumentation lines, the ePTFE sealant tape for threaded joint reduces friction during tightening and prevents galling on stainless steel, titanium, and Hastelloy threads. The PTFE expanded tape for sealing is available in soft, medium, and firm density grades so users can match tape hardness to the available bolt load and flange stiffness. In aggressive media such as hot sulfuric acid, sodium hydroxide, chlorine dioxide, and mixed solvent streams, our chemical resistant ePTFE sealant tape remains chemically inert and does not leach fillers, plasticizers, or lubricants into the process stream.

Our Expanded PTFE Joint Sealant Tape is manufactured in controlled production cells with continuous thickness monitoring, then slit to width and spooled with clean, square edges. The material is available in self-adhesive and non-adhesive versions, on release liners or in bulk rolls, and can be supplied cut-to-length for OEM gasket fabrication. Each production lot is traceable to raw resin batch, expansion parameters, and final inspection records. Before release, samples are tested for density, tensile strength, elongation, compressibility, recovery, creep relaxation, and sealability. The product is FDA-compliant for food contact, USP Class VI certified for biomedical use, and meets RoHS and REACH requirements. Installation requires no curing or solvent cleaning, and the tape can be removed cleanly, reducing downtime compared with paste sealants or fiber-based gaskets. This tape performs consistently under thermal cycling and vibration, making it suitable for both new builds and maintenance repair operations.
