由于焚燒時本產品會揮發出有毒有害物質，可采用填埋方法處理。只有在焚燒爐能夠清除氟化氫和其他酸性燃燒產物的情況下才能焚燒。對本產品的處置必須遵守當地的相關法律法規。 本公司提供全氟離子膜的廢料有償回收服務，詳情請聯系科潤公司銷售人員。

NEPEM® N-417PTFE, N-4110PTFE

MEMBRANES FOR electrolysis

Product Information

NEPEM® PFSA N-417PTFE and N-410PTFE membranes are widely used in chlor-alkali industries, electro-dialysis, recovery of copper from etching solutions, synthesis for gold potassium cyanide , chlorine dioxide, and electrochemical reaction for amino acid. The membrane performs as a conducting separator and solid electrolyte in a variety of electrochemical cells which require the membrane to selectively transport cations across the cell junction.

NEPEM® N-41PTFE series membrane are reinforced membranes based on chemically stable ® perfluorosulfonic acid (PFSA) copolymer. Incorporation of the PTFE mesh reinforcement improves the mechanical property of the composite membrane and allows the membrane to restrict its swelling. The membranes show significant improvements in features such as better resistance to chemical attack and longer operating durability under electrolysing cell conditions.

Order and Packaging Information

Membrane dimensions are based on dry product conditioned at 23 °C and 50% relative humidity(RH) before cutting. The moisture content of the membranes will have an influence on their dimensions changes, including in the length, width, and thickness directions.

The standard product specifications for membrane pieces include:

? Width: 0.20 m (Min.) To 1 .20 m (Max.)

? Length： 0.20 m (Min.) To 1.20 m (Max.)

The membrane for cut pieces will depend on the size and quantity of the customer’s order requirements. All the membranes were pretreated which can be used directly. All the flatted membranes are shipped on a roll. Flat membranes are directly wound into a small roll. The membranes are protected with a polyethylene wrap and inner packaging, then placed in shipping hard cartons. Membrane pieces can be cut to non standard sizes, and special packaging provided at additional cost. Please contact our sales staff for details and availability.

 Recommended Storage Conditions

Prior to opening the original shipping box, the membrane does not require environmentally controlled storage. Membrane should be kept sealed in its original packaging until needed. After opening the package, store the material in a temperature and humidity controlled environment(temperature 25.0±5.0°C and humidity 45±5.0%RH). Acclimatize the membrane to the manufacturing environment for at least 48 hours prior to use. Once opened and exposed to the environment, the membrane will equilibrate to the ambient relative humidity, and change in dimensions accordingly. Scrap Disposal Preferred disposal options are recycling and landfill. Incinerate only if incinerator is capable of scrubbing out hydrogen fluoride and other acidic combustion products. Treatment, storage, transportation, and disposal must be in accordance with applicable national laws and regulations. The process of recycling waste Fluoropolymer Resins is extremely complicated as there are many parts to be recycled and many hazardous materials to remove. Therefore, we recommend that it is more appropriate for customers to hand over the waste film to us for recycling.
