1. Is Teflon the same as Teflon?
Teflon"with"Teflon"In fact, it is a different Chinese name for the same thing, and they are all derived from English brand names"teflon"。Teflon is a trade name for fluorine materials based on polytetrafluoroethylene (PTFE), and due to the pronunciation and translation, there are many other names in China, such as Teflon, Teflon, Teflon, Teflon, Teflon, Teflon, etc.
To put it simply, Teflon is a synthetic polymer material containing fluorine elements, which is characterized by replacing hydrogen atoms in polyethylene with fluorine atoms. This material is super stick-resistant and stable even at high temperatures; It is not afraid of water or moisture, and has strong wear resistance; In addition, it is resistant to acid and alkali corrosion, and is insoluble in almost all organic solvents, so it has a wide range of uses and high durability.
2. What are the types of Teflon?
Teflon (Teflon) can be divided into Teflon PTFE, Teflon PFA, Teflon FEP, Teflon ETFE, Teflon PVDF series.
Teflon PTFE, or polytetrafluoroethylene, is a core member of the Teflon family and is known for its excellent resistance to high and low temperatures. It has a very low coefficient of friction, near-perfect chemical stability, resistance to almost all chemicals, and good electrical insulation. PTFE is widely used in non-stick coatings, seal manufacturing, chemical piping and high-end electronic components.
Teflon PFA (perfluoroalkoxy resin) inherits the excellent properties of PTFE and enhances melt processing fluidity, maintaining stable performance in the range of -80 to +260. PFA has high transparency and strong corrosion resistance, especially suitable for the preparation of thin-walled pipes and complex shape parts, and is often used in clean transmission systems and heat-resistant and corrosion-resistant components in semiconductors, pharmaceuticals and other fields.
Teflon ETFE (ethylene-tetrafluoroethylene copolymer) is a lightweight, high-strength, and highly transparent plastic material with excellent weather resistance and UV stability. It can still maintain good flexibility at low temperatures, and is widely used in building membrane structures, wire and cable insulation, solar cell backsheets and some anti-corrosion products in special environments.
Teflon FEP (fluorinated ethylene propylene copolymer) is also chemically inert and temperature resistant and can be used for long periods of time in environments from -80 to +200. With its smooth surface, low coefficient of friction, and ease of thermoforming, FEP is commonly used in the manufacture of corrosion-resistant pipes, film packaging, heat shrink tubing, and clean fluid transfer systems in the medical and semiconductor industries.
Teflon PVDF (polyvinylidene fluoride) has high mechanical strength and hardness, is particularly resistant to chemicals, is particularly resistant to antioxidants and chlorides, and has an operating temperature range of -40 to +150. Because of its good weather resistance, self-extinguishing and impact resistance, PVDF is widely used in anti-corrosion pipelines, chemical equipment linings, coatings, water treatment membrane materials and lithium-ion battery separators.
Trifluoro, a manufacturer of high-end fluoroplastic products. A new benchmark for high-end fluoroplastics, a new choice for domestic substitution.
