Know Everything About Polysulfone Flim

September 23, 2024

Polysulfone resin is an amorphous thermoplastic specialty engineering plastic. As one of the important varieties of sulfone polymers, polysulfone has good thermal stability, insulation and dimensional stability. Therefore, polysulfone is widely used in electrical and electronic fields, medical, food and other fields, as well as a variety of high-precision fields. Currently more mature polysulfone resin has three categories: bisphenol A type polysulfone (PSU), Polyphenylsulfone (PPSU) and polyethersulfone (PES)

The following are three types of polysulfone structural formulas:

The current status of research on polysulfone presents a multi-faceted and multi-faceted situation. In the optimization of the synthesis process, in the continuous exploration of new catalysts and reaction conditions, in order to improve the efficiency of polysulfone synthesis and product quality; in the improvement of performance, to enhance the mechanical properties of polysulfone, heat resistance, chemical corrosion resistance and other key performance indicators; in the development of environmentally friendly products, with the enhancement of environmental protection awareness, is committed to the development of biodegradable or environmentally friendly polysulfone materials. At the same time, the recycling technology of polysulfone is also being explored to reduce resource waste and environmental pollution.

I. Performance characteristics of polysulfone membrane (PSU)

①Good mechanical properties

HONY Plastic polysulfone film tensile strength and tear strength is higher than ordinary engineering plastics, high mechanical property retention rate under high temperature conditions, tensile strength in the range of -100-150 ℃ change is not significant, with high modulus, high strength characteristics. Its creep resistance is remarkable, in the case of long-term stress, the size change is extremely small.

②Excellent high temperature resistance

HONY Plastic polysulfone film has excellent heat resistance, can maintain stable performance in high temperature environment. Its glass transition temperature is high, usually around 185 ℃, can be used continuously at 160 ℃, short-term use of the temperature can even reach 190 ℃.

③Excellent chemical resistance

HONY Plastic polysulfone membrane has good stability to most inorganic acids, alkalis, salt solutions, able to resist the erosion of chemicals, but it is subject to certain polar organic solvents, such as ketones, halogenated hydrocarbons, aromatic hydrocarbons and so on, corrosion of the phenomenon will occur.

④Good electrical properties

HONY Plastic polysulfone film has excellent electrical properties in a wide range of temperatures and frequencies, and the electrical properties change very little in water and humid air. ⑤ other properties Dafu new material polysulfone membrane transparency is good, 0.2mm thick PSU membrane transmittance up to 88%, radiation resistance is excellent, and low moisture absorption.

Second, polysulfone (PSU) membrane application areas

①Electrical and electronic fields

HONY Plastic polysulfone film has a wide range of applications in the field of electrical and electronic. Because of its excellent electrical properties and high temperature performance, it can be used as Insulation Materials, high temperature parts, coil skeleton and so on. For example, in the production of a variety of contactors, connectors, transformer insulation, SCR caps, insulating bushings, coil skeleton, terminals and collector rings and other electrical parts, its excellent performance to ensure the long-term stability and reliability of electronic equipment.

② In the field of automobile manufacturing

HONY Plastic polysulfone film can be used in the manufacture of engine peripheral parts, transmission system components and electrical connectors. Its high-temperature characteristics make it particularly suitable for use in high-temperature environments near the engine, and at the same time its chemical resistance also protects the car from oil, other corrosive substances damage.

③Food container field

HONY Plastic polysulfone film is a non-toxic product that can be made into utensils that repeatedly come into contact with food, is resistant to gamma and roentgen rays, and slightly leaks microwaves, which makes it suitable for use as microwave oven cooking utensils, which have the advantage of saving energy and time.

In short, HONY Plastic polysulfone film (PSU) as a high-performance engineering plastics, in the future development will continue to innovate and progress, to bring more benefits to human society.
