Material Introduction Tetrafluoroethylene-propylene rubber (TFE/P), commercially known as AFLAS, is a specialty fluoroelastomer produced by the alternating copolymerization of tetrafluoroethylene and propylene. It exhibits superior performance compared to conventional fluoroelastomers (FKM), demonstrating exceptional resistance to high-temperature chemical corrosion, steam, and aggressive acid and alkali environments. AFLAS displays excellent stability against highly corrosive media such as concentrated sulfuric acid, concentrated nitric acid, hydrofluoric acid, and caustic soda, as well as high-temperature water and high-pressure steam—conditions under which standard FKM typically fails. Furthermore, it is compatible with amines, sour hydrocarbon streams containing …

Material Introduction Tetrafluoroethylene-propylene rubber (TFE/P), trade name AFLAS, is a special fluororubber formed by the alternating copolymerization of tetrafluoroethylene and propylene. AFLAS 200 and AFLAS 300 are high-performance grades in this series developed for more harsh dynamic sealing and ultra-high temperature chemical environments. On the basis of maintaining excellent chemical corrosion resistance, they further optimize compression set, high-temperature resistance and dynamic fatigue life. The core differences between AFLAS 200 and AFLAS 300 are as follows: AFLAS 200: Focuses on extremely low compression set and excellent dynamic seal retention capacity, suitable …

Material Introduction Viton FDA-certified fluoroelastomer, a vinylidene fluoride-hexafluoropropylene copolymer or its terpolymer variant, is a specialty fluoroelastomer manufactured through proprietary formulations and rigorous production processes to comply with the US FDA and EU Regulation (EU) 10/2011 food contact standards. While retaining the exceptional high-temperature and chemical resistance inherent to Viton, it ensures safety for contact with food, pharmaceutical products, and potable water. Viton FDA exhibits outstanding high-temperature performance, with a typical service temperature range of -20°C to +220°C; specialty low-temperature grades can reach as low as -40°C. It is capable …

Material Introduction Fluoroelastomer (FKM), with Viton being the most recognized brand name, is a high-performance synthetic rubber characterized by exceptional chemical resistance and outstanding high-temperature performance. Based on its monomer composition and fluorine content, common types include Viton A (a dipolymer fluoroelastomer), Viton B (a terpolymer fluoroelastomer), and Viton F (a high-fluorine-content fluoroelastomer). Fluoroelastomer exhibits excellent high-temperature resistance, maintaining its physical and mechanical properties over prolonged exposure to elevated temperatures. The typical service temperature range for standard FKM is -20°C to 200°C; low-temperature specialty grades can operate as low as …

Material Introduction The Viton GB/GF series fluororubber belongs to the family of vinylidene fluoride-hexafluoropropylene copolymers (FKM) and its terpolymers. It is a high-grade grade within the Viton brand, featuring balanced comprehensive performance, excellent processing performance, and outstanding resistance to media. Specifically, the GB series focuses on general-purpose high-performance oil and heat resistance, while the GF series further enhances the chemical resistance (especially to alcohol-containing fuels and acidic gases) and low-temperature flexibility based on the GB series. Viton GB/GF exhibits excellent high-temperature resistance, with a typical operating temperature range of -25℃ …

Material Introduction VITON ETP (Extra Thermal Performance, also known as “Enhanced Temperature Performance” in some models) is a high-performance fluororubber, which is an improved version of tetrafluoroethylene propylene (TFE/P) or special copolymer fluororubber. It boasts a wider operating temperature range and superior chemical resistance compared to standard fluororubber (FKM). VITON ETP exhibits exceptionally superior high-temperature resistance, with a continuous operating temperature range extending from -30℃ to +250℃, and a short-term peak tolerance of +275℃. Compared to traditional fluororubber, it exhibits reduced compression set at elevated temperatures and maintains sealing force …
