The advantages of PES plastics
2023-05-30
PES plastic is a kind of engineering plastic with high temperature resistance, good hardness and significant long-term thermoplastic bearing capacity, it is by 4,4 '-disulfonyl chloride diphenyl ether under the catalysis of anhydrous ferric chloride, and diphenyl ether condensation material, industry referred to as PES plastic. What are the advantages of this plastic?
1. Good heat resistance. This engineering plastic is stable at a high temperature of 200 degrees.
2. With creep resistance, it can still be used at 180 degrees under load, and the strain under 150 ° C and 20MPa pressure is only 2.55%.
At the same time, it is also slightly able to absorb water, and the deformation range after equilibrium is about 0.15%, and its creep resistance is one of the most excellent thermoplastic resins in the temperature range below 180℃.
3. As a special adhesive and coating, it can withstand temperature of more than 200 degrees. Between polysulfone and polyaromatic sulfone, long-term use temperature 180-200 ℃.
4. Good chemical resistance, acid, alkali and straight chain hydrocarbon resistance, gasoline corrosion.
5. With high rigidity, self-flame retardant and low smoke when burning, without adding any flame retardant that has excellent flammability.
6. Good resistance to steam and superhot water (150-160 ℃), poor ultraviolet resistance, excellent electrical performance, fire resistance grade V-O. It can withstand 150 ~ 160℃ hot water and steam, even at high temperatures, it is not affected by acid and alkali erosion.
7. Dimensional stability, that is, linear expansion, has a small coefficient, and its temperature reliability is also small. It is characterized by 30% glass fiber reinforced PES resin, whose linear expansion coefficient is only 2.3×10 /℃, and it can still maintain a similar value to aluminum until 200℃.
PES plastic is widely used in the field of machinery, electrical, electronic, automotive, hot water, medical equipment, food processing machinery and other fields, it has these advantages you know?
