Ii. Analysis of Coating Advantages: Why PESU 7020P?<\/span><\/h2>\n

 <\/p>\n

In the field of coating film materials, the key lies not only in \"heat resistance\", but also in \"stability during the film-forming process, uniformity of the film structure after coating and chemical compatibility\". The PESU 7020P precisely hits the following key advantages:<\/span><\/p>\n

\u2705 High-viscosity film formation, enhancing surface consistency<\/span><\/strong><\/p>\n

Its ultra-high relative viscosity ensures that the coating liquid spreads evenly on the substrate surface, forming a continuous and poreless film structure, which is suitable for high-precision battery separators.<\/span><\/p>\n

\u2705Soluble in a variety of solvents, suitable for a variety of processes<\/span><\/strong><\/p>\n

It can be made into a uniform coating liquid through polar solvents such as DMSO and NMP, and is compatible with existing coating production lines, facilitating seamless upgrades.<\/span><\/p>\n

\u2705 Strong thermal stability, enhancing the thermal shrinkage resistance of the diaphragm<\/span><\/strong><\/p>\n

With a glass transition temperature of 230\u00b0C, it maintains dimensional stability and is less prone to warping at high temperatures, making it particularly suitable for functional layers in high-temperature charging and discharging scenarios.<\/span><\/p>\n

\u2705Good chemical inertness and compatible with multiple electrolytic systems<\/span><\/strong><\/p>\n

It demonstrates excellent solvent resistance when exposed to lithium-ion electrolytes, alkaline media, alcohols and ether solutions, providing long-term reliable protection for coated components.<\/span><\/p>\n
