PES features When heat resistance, thermal deformation temperature at 200 ~ 220 ℃, continuous use temperature is 180 ~ 200 ℃, UL temperature index of 180 ℃. Does the hydrolysis resistance, resistant to 150 ~ 160 ℃ hot water or steam, is not subject to acid, alkali at high temperature.
When the temperature dependence of the modulus, the modulus of in - 100 ℃ to 200 ℃ is almost the same, especially in the more than 100 ℃ is better than any kind of thermoplastic resin.
Does creep resistance: under 180 ℃ temperature range of the creep resistance of thermoplastic resin is one of the most excellent, especially the glass fiber reinforced PES resin than some thermosetting resin.
Does size stability: linear expansion coefficient is small, and its temperature dependence is small is its characteristic. Characterized by 30% glass fiber reinforced PES resin, the linear expansion coefficient of only 2.3 x 10-5 / ℃, and until 200 ℃ can still maintain value and aluminum.
Have resistance to impact: it has the same impact resistance as the polycarbonate. Don't enhance resin can be riveting, but to the nozzle
Are more sensitive incision and design should pay attention to.
Does non-toxic: in terms of health standards, by the us FDA approval, also accord with the Japanese ministry announcement no. 178 and 178.
Have flame retardant sex: has the self-extinguishing, don't add any was excellent flame retardant, flame retardant grade of UL94V - 0 (0.46 mm)
When chemical resistance: PES resistant to gasoline, oil, lubricating oil and other oils and freon cleaner, such as solvent cracking resistance of it is the best crystal resin. But it acetone, chloroform and other polar solvent resistance is bad, should be careful when using.


PES advantages in the field of coating
Because it has a good adhesion with iron, lead and other metal, coating high surface hardness, etc. The PES polyether sulfone and ptfe can be made into good corrosion resistance, radiation protection, insulation performance, flame retardant, non-toxic, the best non-stick coating adhesion with metal, the characteristics of low friction. Widely used in kitchen appliances, household electrical appliances, light industry, hardware, industrial molds, plastic machinery and other industries.
In addition, PES can be processed into superfine powder, used in powder coating and coating of liquid.
When heat resistance, thermal deformation temperature at 200 ~ 220 ℃, continuous use temperature is 180 ~ 200 ℃, UL temperature index of 180 ℃.
