乙烯三氟氯乙烯共聚物 Ethylene-chlorotrifluoroethylene copolymer 此材料从低温到 330T的性能良好，其强度、耐磨性、抗蠕变性大大高于PTEE、FEP和PFA。它在室温和高温下耐大多数腐蚀性化学品和有机溶剂。它的介电常数（2.6）低，在很宽的温度和频率范围内性能稳定。ECTFE不着火，可防止火焰扩散，当暴露在火焰中时，将分解成硬质的碳。 [1] ECTFE可制成用于模塑和挤塑的粒料及用于旋转模塑、流化床涂饰、静电涂饰的粉状产品。可在传统挤塑设备用化学发泡法加工成泡沫状产品，待别适用于计算机用电线的领域。半成品有膜、板、管和单纤维。 Ausimont USA公司销售的ECTFE产品牌号为Halar。 在电线和电缆领域，最重要的应用是用于增压电缆、公共交通车用电缆。火警电缆、阳极保护电缆。注塑产品有塔填料、问和泵零件、接插件、电线接线柱、过滤机壳。ECTFE管的应用有光导纤维的套管、非支撑管、钢管和增强塑料管的内衬。 ECTFE涂料和内村可防止金属被环境侵蚀。膜的应用有理电池和隔离方面的应用。单纤维的应用有消油雾器、编织套管、过滤织物。宽幅（48in）以玻璃纤维作背村的ECTFE片材，可用作耐化学品和强度要求高的槽罐的内衬。 Solvay Specialty Polymers Halar® 2408DA Ethylene Chlorotrifluoroethylene Copolymer (ECTFE) Material Notes: Halar® 2408DA is a filled, pearl-white, semicrystalline melt processable fluorinated resin that may be used in full compliance with the federal Food, Drug, and Cosmetic Act. It is designed for electrostatic powder coatings and is particularly recommended for use in protection and anti-corrosion applications where food contact compliance is required. Halar® 2408DA provides superior water vapor permeation resistance compared to Halar® 6014. It also exhibits very good chemical, electrical and thermal properties. Additionally Halar® 2408DA coatings show very good surface finish and hardness. Main features of Halar® 2408DA include: - Food contact compliance - Very good chemical resistance - Very good thermal properties - Optimum permeation resistance - Outstanding flame resistance - Very good surface characteristics - Purity Key Attributes: Chemical Resistant; Corrosion Resistant; Food Contact Acceptable; Good Electrical Properties; Good Surface Finish; Good Thermal Stability; High Hardness; High Purity; Semi Crystalline Applications: Coating Applications Processing - Halar® 2408DA can be processed using normal electrostatic powder coating techniques. Generally the procedure involves substrate preparation, spray coating, baking and cooling. Depending on the application further processing can be carried out. Several passes maybe required to obtain the desired Halar load and build up coating thickness. - Halar® 2408DA can be used neat and without any further formulation. Substrate preparation, gun parameters such as voltage and both oven temperature and time must all be well controlled to achieve defect free coated items. Storage and Handling - Halar® melt processable fluoropolymer resins can be stored without shelf life issues when kept in a clean and dry area at ambient temperatures. Opened containers should be tightly resealed to prevent any contamination. Safety and Toxicology - Before using Halar® melt processable fluoropolymer resins consult the product Material Safety Data Sheet and follow all label directions an handling precautions. - As with all fluoropolymer 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 contact 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. Information provided by Solvay Specialty Polymers.
