At present, many developed countries mostly use polytetrafluoroethylene and use PTFE sealing tape as the isolation layer to develop medical protective clothing. It has physical and mechanical properties such as waterproof, water-repellent, antibacterial, and antistatic, and is effective against blood and viruses. Has very good barrier properties.
After the dry curing sealant liquid is applied, the solvent quickly evaporates and solidifies, resulting in poor viscoelasticity and poor detachability of the film.
The body of this type of sealant mainly includes thermosetting resins such as phenolic resin, epoxy resin, and unsaturated resin, and some use natural resins (such as gum arabic).
ptfe sealing tape is also called sealing tape and anti-leak tape.
It is a strip product made of polytetrafluoroethylene dispersion resin through paste extrusion and calendering without any additives.
It is white, has a smooth surface, and has a uniform texture. It has excellent heat resistance and corrosion resistance, and has good self-adhesiveness, good fit, and good sealing properties.
It can be widely used for thread sealing of pipelines such as pure oxygen, coal gas, strong oxidants, highly corrosive media, and high-temperature steam, as well as filling seals of complex shapes in pumps, valves, and equipment.
PTFE film manufacturer specializes in the production of PTFE sealing tape. It has a full set of advanced production equipment and technology. It also has an advanced clean room and an independent composite slitting workshop to ensure the production quality of PTFE film; the product materials produced are all made of Imported raw materials, high uniformity, stable performance, good air permeability, filtration efficiency up to 99.999995%! It can basically meet the filtration efficiency grade requirements of sub-high efficiency, high efficiency and ultra high efficiency filters.
