What is Polyether Sulfone<\/span><\/h1>\n

 <\/p>\n

As material applications become increasingly sophisticated and multifunctional, traditional granular thermoplastic engineering plastics are no longer sufficient to meet the needs of some cutting-edge industries. The new polyether sulfone material, PESU 2020 P SR, provided in the form of film or coating, is providing new solutions for functional coatings, membrane materials and high-end modified plastics with its unique properties.<\/span><\/p>\n

01 | Material analysis: Starting from the structure of Polyether sulfone, understand the special features of PESU 2020 P SR<\/span><\/h2>\n

 <\/p>\n

Polyether sulfone (polyethersulfone) is a non-crystalline polymer with high glass transition temperature (Tg), good thermal stability and chemical inertness. Its molecular skeleton contains both flexible ether bonds (-O-) and rigid sulfone groups (-SO\u2082-). This makes it both flexible and able to maintain stable performance in high temperature and organic chemical environments.<\/span><\/p>\n

As a film\/sheet grade material in BASF's polyether sulfone products, PESU 2020 P SR is particularly suitable for the following types of processing or application methods:<\/span><\/p>\n

\u00a0 \u30fb<\/strong>Dip Coating<\/span>
\n\u00a0 \u30fb<\/strong>Knife Coating<\/span>
\n\u00a0 \u30fb<\/strong>Functional membrane preparation (separation membrane, diaphragm, interface layer)<\/span>
\n\u00a0 \u30fb<\/strong>Compounded with other materials to form a high value-added membrane structure<\/span><\/p>\n

03 | Application innovation: How does PESU film empower future coating and diaphragm technologies?<\/span><\/h2>\n

 <\/p>\n

1\ufe0f\u20e3 Heat-resistant coating for battery separators<\/span><\/strong><\/p>\n

As the safety requirements for lithium batteries continue to increase, conventional PE and PP separators may melt or shrink during thermal runaway. The heat-stable coating prepared with PESU 2020 P SR can provide:<\/span><\/p>\n

\u00a0 \u30fb<\/strong>Dimensional stability at 300\u00b0C<\/span>
\n\u00a0 \u30fb<\/strong>Anti-melt puncture protection<\/span>
\n\u00a0 \u30fb<\/strong>Higher electrolyte wettability<\/span><\/p>\n

\ud83d\udc49 Many separator companies have explored using it as a coating resin to improve the \"delayed combustion\" ability of lithium batteries after thermal runaway.<\/span><\/p>\n

2\ufe0f\u20e3 Interface treatment of medical-grade separation membranes or conductive layers<\/span><\/strong><\/p>\n

PESU has natural biocompatibility and chemical resistance and can be used to prepare:<\/span><\/p>\n

\u00a0 \u30fb<\/strong>Medical ultrafiltration membranes (blood purification, virus retention)<\/span>
\n\u00a0 \u30fb<\/strong>Implant device coatings or biosensor membranes<\/span>
\n\u00a0 \u30fb<\/strong>Base membranes in thin film sensors<\/span><\/p>\n

\ud83d\udc49 Using PESU 2020 P SR, a coating system with a uniform thickness of less than 50\u03bcm can be prepared without sacrificing stability, thereby improving the accuracy of device integration.<\/span><\/p>\n

3\ufe0f\u20e3 High-end structural modification carrier<\/span><\/strong><\/p>\n

In addition to independent use, PESU 2020 P SR can also be used as a functional additive or interface coupling layer material for other engineering plastics to achieve:<\/span><\/p>\n

\u00a0 \u30fb<\/strong>Interface bonding enhancement with reinforcing materials such as carbon fiber and aramid<\/span>
\n\u00a0 \u30fb<\/strong>As an anti-stress cracking factor in PA, PPS, and PEEK modification<\/span>
\n\u00a0 \u30fb<\/strong>As an intermediate buffer layer in aviation-grade composite materials to improve interlayer toughness<\/span><\/p>\n
