Product Description

Perfluorosulfonic Acid Ion-Exchange Resin is a special fluorine-containing polymer with excellent stability and chemical resistance, widely used in fuel cells, flow batteries, lithium-ion rechargeable batteries, hydrogen electrolyzer, chlor-alkali industry electrolyzer equipment, sewage disposal, chemical catalysis, photocatalysis, gas separation, functional composite materials and other fields.

Storage

1.Store in a sealed package；

2.Store in a clean and dry environment, away from direct sunlight. The recommended storage temperature is 25±5℃/77±9℉.

Test Requirements:

1.Place the product in a laboratory environment(23±2℃/73.4±3.6℉, 50±5% RH)for at least 24hours before testing；

2.Test temperature: 270℃/518℉, counterweight 2160g；

3.Test after resin transformation treatment. Testing method follows theChinesenational standard “GB/T 20042.3-2022”.

Dispersing Instructions:

1.Please confirm the product model, exchange equivalent and solid content of the resin according to the label provided (Note: perfluorosulfonic acid resin is hygroscopic, and the resin moisture contentis about 10%);

2.Please prepare the solvent in advance and pre-mix it. lt is recommended to use n-propanol andwateras solvent for dispersion, with a solvent mass ratio of 1:1;

3.The recommended solid content range for the dispersion is 0.1%-30%；

4.When weighing the resin, please pay attention to changes in the ambient temperature and humidity. It is recommended to perform the weighing in a laboratory environment, with acontrolledtemperature at 23±2℃ and a relative humidity of 50±5%RH. Large temperature and humidity changes  lead to changes in the moisture content of the powder, ultimately resulting in deviation of the solid content of the dispersion;

5.The preparation of the dispersion can be carried out without any additional heating or inert gas protection. During the process of adding the resin to the solvent, it is recommended to use magnetic or mechanical stirring to ensure a thorough mixture of the powder and solvent;

6.To prepare a dispersion with a solid content ≥10%, please add the powder to the stirred solvent multi times, avoiding of sticking the powder to the container wall;

7.The dispersion solid content decides thestirringtime. It is recommended to stir for not less than 4 hours when preparing dispersions with solid content＜10%, and not less than 8 hours when preparing dispersions with solid content＞10%;

8.If large particles are found in the dispersion when practicing particle size test(≥1μm), please contact Hyproof custom service.
