Algoflon® DF 261 F is a white fine coagulated powder and is produced without any intentional use or addition of PFOA. It is designed for paste extrusion in low reduction ratio (RR) range. It is recommended for manufacture high tenacity items as full density tapes, fibers and membranes. Algoflon® DF 261 F shows large processing range and higher productivity. Main features of Algoflon® DF 261 F include: - Low sintering temperature - Excellent tenacity - Good stretchability - Good dimension stability - Higher productivity Key Attributes: Chemical Resistant; Good Processing Stability; Good Stretchability; Good Thermal Stability; Low Friction Applications: Aerospace Applications; Automotive Applications; Electrical/Electronic Applications; Fibers; Industrial Applications; Membranes; Wire & Cable Applications; Yarn Agency Ratings: FDA 21 CFR 177.1550 Processing - Algoflon® DF 261 F is processed according to methods conventionally used for paste extrusion. Initially the powder is mixed with a lubricant to produce a paste. This is then compacted into a preform and extruded through a finishing die using a ram extruder. Further processing as calendering, removal of lubricant, stretching and sintering are carried out to make final products such as yarns. - Mixing, performing, calendaring, stretching and sintering steps must all be carefully coordinated and controlled to avoid production waste. Storage and Handling - Algoflon® PTFE fine coagulated powders must be stored and handled carefully to avoid excessive shearing and particle fibrillation. Fibrillation is irreversible and damaged particles can appear as defects in manufactured articles. - PTFE fine coagulated powders must be handled below 19°C because above this temperature, the powders are softer and can be more easily laminated. It is recommended sieving of powders below 19°C before adding lubricant. Strong vibrations and shocks must be avoided as much as possible for prevent lumps formation. - Storage and transportation should be carried out in the range 5 - 19°C. Moreover, the powders must be stored in a dry room because the absorption of moisture could negatively affect its processing. - Storage and handling facilities should be clean since even very small foreign particles can cause defects in finished products. Keep resin drums closed and clean. Good housekeeping and careful handling are essential. Safety and Toxicology - Before using Algoflon® PTFE fine coagulated powders consult the product Material Safety Data Sheet and follow all label directions and handling precautions. - As with all PTFE materials, handling and processing should only be carried out in well ventilated areas. Vapor extractor units should be installed above processing equipment. Fumes must not be inhaled and eye and skin contact ought to be avoided. In case of skin contacts wash with soap and water. In case of eye contact flush with water immediately and seek medical help. Do not smoke in areas contaminated with powder, vapor or fumes. - See Material Safety Data Sheet for detailed advice on waste disposal methods. Packaging - Algoflon® DF 261 F is packaged in 25 kg non returnable drums. Information provided by Solvay Specialty Polymers. |
