Polyethersulfone; A Relatively New Class Of Polymer Used In Various End-Use Industries
Polyethersulfone (PES) is a sulfone plastic that belongs to the class of thermoplastic polymers. These polymers have high chemical resistivity, have high rigidity, are light in weight, exhibit excellent electrical properties at high temperature, and also remain stable at high temperatures. Thus, they are widely used in printed circuits, machine guards, safety face shields, connectors, and others due to the aforementioned properties. It is a transparent, high-performance polymer known for its dimensional stability at high temperatures in both the air and the water. At room temperature, polyethersulfone is rigid, ductile, and strong, with excellent creep resistance. It is an amorphous, transparent, and pale amber high-performance thermoplastic.
Moreover, polyethersulfone (PES) is the most temperature resistant, transparent commercially available thermoplastic resin. PES is a high temperature engineering thermoplastic with high stability and mechanical strength. Polyethersulfone is a high-performance thermoplastic that is dimensionally stable at high temperatures and has outstanding creep and fracture resistance. This material is easy to process and exhibits low mold shrinkage. Its properties make it an excellent choice for use in consumer goods and medical equipment. Its high processing and production speed make it an excellent choice for thermoplastics. Thermoplastic properties of polysulfones make it an ideal material for high-temperature components.
Polyethersulfone are versatile engineering thermoplastics that possess excellent chemical and thermal resistance. In addition to these, polysulfone is also biocompatible and can withstand high temperatures. It is approved for drinking water and can withstand corrosive environments. Moreover, it has excellent mechanical and electrical properties. Its high dimensional stability makes it a desirable material for applications in various fields. Polyethersulfone is an excellent choice for a wide range of industries. Its excellent chemical resistance and thermal stability allow it to replace thermoplastic materials such as polycarbonate, and it is an ideal material for parts that need high toughness.
Polyethersulfone is also able to withstand prolonged exposure to hot chlorinated water. It is often used for drinking water. It is a good choice for a variety of high-temperature and corrosive media applications. Thus, it is majorly used in manufacturing of filters of water purifiers. It is a transparent, strong, and rigid material. These thermoplastic polymers can be processed by hot forming, extrusion, or injection molding. Polyethersulfone is considered one of the well-known material to be used to make ultrafiltration, microfiltration, and gas separation membranes since it provides unique properties such as outstanding hydrolytic, mechanical, and thermal strength in both hot and wet environments.
Polyethersulfones are very high temperature resistant amorphous thermoplastics that are used where the performance requirements exceed the capabilities of other engineering plastics. Thus it is often used in the automotive industry wherein superior mechanical and thermal properties relating to conventional resins are required. PES resin is reinforced with carbon fibers, which is used in automotive components such as transmission parts, oil control pistons, battery caps, carburetor parts, ignition components, bearing cages, oil pumps, and others, thereby replacing thermoset and metal materials. High-temperature oil and gas resistance allow polyethersulfone to be used in automotive applications.
Thus, there is an increasing demand for polyethersulfone form various end-use industries, such as automotive, medical, water treatment, household, electronics and electrical, industrial, nad others (aerospace and military).
