Understanding Aqua Regia and Its Corrosive Power Aqua regia, known as the "king of acids," is a highly corrosive mixture of concentrated hydrochloric acid and nitric acid in a 3:1 ratio. Famous for its ability to dissolve noble metals like gold and platinum, aqua regia presents an extreme challenge for most materials. But which elastomer can withstand its aggressive nature? Let's compare fluororubber (FKM) and perfluoroelastomer (FFKM) to determine which performs better in acid resistance. Fluororubber (FKM): Tough and Acid-Resistant Fluororubber is well-regarded for its resilience against strong acids, making it a widely used material in harsh chemical environments. Key Acid Resistance Properties: Hydrochloric Acid (HCl, 36%): While most materials degrade, fluororubber remains stable. Sulfuric Acid (H₂SO₄, 10%-98%): From dilute to concentrated solutions, fluororubber holds up exceptionally well. Nitric Acid (HNO₃, 10%-50%): Strong resistance to nitric acid, retaining its integrity. High-Temperature Durability: Soaked in 67% sulfuric acid at 140°C, fluororubber maintains its structural stability. Type 23 Fluororubber: Enhanced Performance A specialized variant, Type 23 fluororubber, offers superior acid resistance. When immersed in 98% nitric acid for 27 days, it experiences only 13%-15% volume swelling. It also withstands fuming nitric acid and concentrated sulfuric acid. Against aqua regia, its resistance rating is "2", meaning it can endure for a limited time but is not fully impervious. Perfluoroelastomer (FFKM): The Ultimate Acid-Resistant Material Perfluoroelastomer (FFKM) is considered the gold standard for extreme chemical resistance, making it a top choice for environments exposed to aqua regia. What Makes FFKM Superior? FFKM’s molecular structure replaces nearly all hydrogen atoms with fluorine, forming robust C-F bonds (bond energy ~485 kJ/mol), resulting in three key advantages: Ultra-Low Surface Energy (15-20 mN/m): Ensures anti-stick and self-cleaning properties, ideal for high-purity applications. Exceptional Chemical Stability: Resists highly concentrated acids, bases, and strong oxidizers, making it far superior to standard elastomers. Extreme Durability: Performs reliably in harsh petrochemical environments, resisting high heat, pressure, and corrosion over extended periods. Applications: Choosing the Right Elastomer Fluororubber (FKM): Best suited for general acid-resistant applications where exposure is limited. Perfluoroelastomer (FFKM): The preferred choice for extreme chemical environments, including aqua regia exposure. Both materials are widely used in chemical processing, pipelines, and sealing applications. As material science advances, even more acid-resistant elastomers may emerge, offering enhanced durability and performance. Quick Q&A Q: Can aqua regia corrode all rubber materials? A: Not entirely. Fluororubber provides moderate resistance, while perfluoroelastomer offers significantly better protection against corrosion. Q: Is perfluoroelastomer expensive? A: Yes. Its superior chemical resistance and durability come at a higher cost compared to fluororubber. Conclusion For applications requiring resistance to aqua regia and other aggressive acids, FFKM is the superior choice, while FKM serves as a cost-effective alternative for general acid resistance. Choosing the right material depends on the severity of the chemical exposure, operational temperature, and budget considerations. Looking for high-performance fluoropolymer materials?

High-purity Perfluoroalkoxy (PFA) resin is a crucial material in industries requiring superior chemical resistance, high thermal stability, and excellent electrical insulation properties. The production of high-purity PFA is a complex and multi-stage process, demanding strict control of conditions and advanced equipment. Below is an overview of the main steps involved in the production of high-purity PFA resin. Key Steps in the Production of High-Purity PFA Resin 1. Monomer Synthesis Raw Material Preparation: The primary raw materials for high-purity PFA production are tetrafluoroethylene (TFE) and perfluoroalkyl vinyl ether (PAVE). TFE is typically produced from minerals like fluorite, while PAVE is synthesized through multiple chemical reactions and requires careful purification to achieve the desired purity level. Polymerization Reaction: TFE and PAVE monomers are polymerized in a reaction vessel using a catalyst. The polymerization process takes place under controlled temperature (50°C to 100°C) and pressure (1 MPa to 5 MPa) conditions. This reaction generally lasts for several hours to ensure optimal polymer formation, and controlling these variables is essential to the quality of the final product. 2. Post-Processing Crushing and Sieving: After polymerization, the PFA resin is typically in the form of solid blocks or granules. These need to be crushed and sieved to achieve a uniform particle size distribution. Consistent particle size is important for subsequent processing and application. Washing and Drying: The PFA powder is washed several times to remove any residual monomers, catalysts, or other impurities. Organic solvents or water are commonly used for the washing process. After washing, the material is dried using specialized equipment to ensure that the moisture content is below the acceptable limit for packaging and further processing. 3. Purification Extraction and Distillation: To achieve high purity, PFA resin undergoes further purification through extraction and distillation methods. These processes help remove remaining impurities and increase the purity of the resin. Careful selection of solvents and distillation conditions ensures the highest level of purity. Critical Fluid Processing: Critical fluid technology, particularly using supercritical carbon dioxide, is becoming increasingly popular for purifying high-purity PFA. This method allows for effective purification under mild conditions, reducing the risk of introducing new impurities during the process. 4. Quality Testing and Packaging Quality Control: Throughout the entire production process, quality control is essential to ensure that the PFA resin meets the required specifications. PFA is tested for properties such as purity, molecular weight, particle size distribution, thermal stability, and chemical resistance. Only materials passing these tests are considered high-purity PFA and are ready for packaging. Packaging and Storage: Once the PFA resin meets the required quality standards, it is carefully packaged to prevent contamination during storage and transportation. Sealed plastic or metal containers are typically used, and the material must be stored in a cool, dry, and well-ventilated area to maintain its quality. Why High-Purity PFA Matters High-purity PFA is widely used in critical applications, including electronics, pharmaceuticals, and chemical processing, where its excellent chemical resistance, high thermal stability, and electrical insulation properties are essential.

How is the daily mineral water bottle made? Mineral water bottles are typically made from PET (Polyethylene Terephthalate) plastic. The manufacturing process includes the following key steps: 1. Raw Material Preparation The first step involves preparing PET plastic pellets, which are known for their excellent transparency, heat resistance, and mechanical strength, making them ideal for food packaging, such as mineral water bottles. 2. Injection Molding of Preforms PET pellets are heated and melted, then injected into molds to form preforms. These preforms resemble a smaller version of a bottle, with a thicker bottom and a narrower middle. They will later be stretched and blow-molded into the final shape of the mineral water bottle. 3. Stretch Blow Molding The preforms are heated and sent to a blow molding machine. Inside the machine, the preforms are first preheated, then stretched, and air is blown into them at high pressure, expanding them to the shape of the mold. This process shapes the bottle and ensures its proper size and thickness. 4. Cooling and Demolding The newly formed bottles are cooled, typically with air or water, to ensure they retain their shape and strength. Once cooled, they are removed from the mold. 5. Quality Inspection and Packaging The bottles undergo a series of quality checks, including tests for strength, sealing, and appearance, to ensure they meet production standards. Bottles that pass inspection are sent to the packaging line and prepared for delivery to filling plants. 6.

Fluoroplastic is a general term for polymer compounds containing fluorine atoms in the main chain of molecules. Fluorine plastics have excellent heat resistance, cold resistance, weather resistance, drug resistance, solvent resistance, insulation properties and high frequency electrical properties. It has the characteristics of non-drying, self-lubricating, low friction coefficient and so on. Polytetrafluoroethylene, perfluorinated (ethylene-propylene) copolymer (FEP) is entirely composed of carbon and fluorine atoms, while polyvinylidene fluoride (PVDF), polyvinyl fluoride (PVF) molecules also contain hydroproons, polytrifluoroethylene chloride also contains chlorine atoms. The excellent properties of fluoroplastics are achieved by the high binding energy between carbon atoms and fluorine atoms. The backbone of polytetrafluoroethylene is carbon atoms, and it is completely surrounded by fluorine atoms, so its various properties are higher, and PFA, FEP, ETFE and other varieties due to the influence of the side group, the softening point is low PTFE, and other properties have also changed. 1. Thermal performance: fluorine plastics have flame resistance and excellent heat resistance. The continuous use temperature of PTFE and PFA can reach 260 ° C, and it can be used at 300 ° C for a short time. FEP is used at temperatures 60 ° C lower than they are. The higher PCTFE can be used at 120℃. Fluoroplastics such as long-term use at high temperatures will cause crystallinity changes, especially when manufacturing equipment lining. 2. Drug resistance: fluorine plastics have excellent drug resistance and solvent resistance, especially PTFE, PFA, FEP, etc., acid, alkali, solvent are not etched on them. But molten alkali metals, fluorine, trifluorofluorocarbons have different degrees of influence on them. PCTFE, ETFE, PVDF, etc., are slightly less resistant to drugs in fluoroplastics, but the corrosion resistance is still much better than that of other plastics. 3. Electrical properties: The electrical properties of fluorine plastics, especially the high-frequency electrical properties, are difficult to match other materials. The polarity of PTFE, FEP and PFA molecules is very low, the change is very small in a wide temperature and frequency range, the relative dielectric constant is stable, the dielectric loss is very low, and the electrical insulation is excellent. PVDF also has specific piezoelectric and pyroelectric properties, which can be used to manufacture piezoelectric materials. 4. Mechanical properties: The increase of hydrogen and chlorine atoms in fluorine plastic molecules will also increase its tensile strength. PTFE and PCTFE have extremely low embrittlement temperatures, showing excellent low temperature properties. PTFE has a low coefficient of friction and special self-lubricity. However, PTFE has its own shortcomings such as high wear and cold flow. Various fillers can be used to improve wear resistance and overcome cold flow. 5. Non-stickiness: fluorine plastics have specific non-stickiness. In particular, the fluorine content of PTPE, FEP, PFA and other molecules is high, and the surface contact Angle is very large, so that the liquid on the surface of fluoroplastic products becomes spherical. It is not easy to bond with resin, so it is often used to make non-stick creep layer on the surface of cookware. 6. Weather resistance: all varieties of fluorine plastics have excellent weather resistance, even in harsh temperatures for long-term exposure, its various properties have not changed. 7. Hydrophobicity: The water absorption of fluorine plastics is low, especially PTFE. Its hydrophobicity can be used to make permeable composite fabrics and other equipment.   Characteristics and uses of the main varieties of fluorine plastics Product Name Characteristic Applications.
