First, the material properties of PES
PES is a transparent amber-colored amorphous resin with colorless appearance, high transparency, high temperature resistance, milk wear, excellent heat resistance, excellent dimensional stability, and good chemical resistance. In addition, PES shows excellent reliability to rapid temperature changes and has excellent reliability for long-term use at high temperatures. PES has a wide range of applications due to its excellent processing and molding properties; it is not easily deformed, is resistant to high temperatures, and has high stability and chemical resistance; PES shows excellent reliability against rapid temperature changes, and its excellent processing properties make PES widely used.
PES has excellent heat resistance, physical and mechanical properties, insulation properties, etc., in particular, it has the ability to be used continuously at high temperatures and in environments with rapid changes in temperature can still maintain the stability of the performance of the outstanding advantages, has been widely used in many fields.
PES and polybutylene succinate (PBS) are homologous, easily decomposed and metabolized by a variety of microorganisms in nature or by enzymes in plants and animals, and eventually generate carbon dioxide and water. It is often used as a substitute or filler for PBS, which not only saves costs but also improves certain properties of the material to achieve unanticipated effects while maintaining the same product performance. Based on the biodegradability of PES, it has great prospects for development in plastic film, food packaging, biological materials and so on.
Application of PES
1, Heat resistance, heat transformation temperature of 200 ~ 220 ℃ continuous use temperature of 180 ~ 200 ℃, UL temperature index of 180 degrees Celsius
2, Hydrolysis resistance, can be resistant to 150 ~ 160 ℃ hot water or steam, in the high temperature is not subject to acid and alkali erosion.
3, The modulus of the temperature dependence of its modulus in -100 ℃ to 200 ℃ almost unchanged, especially in the 100 ℃ than any kind of thermoplastic resins are good
4, Creep resistance, in the temperature range of 180 ℃ below its resistance to change is an excellent thermoplastic resin, especially glass fiber reinforced PES resin is better than some thermosetting resin.
5, Dimensional stability, the coefficient of linear expansion is small, and its temperature dependence is also small is its characteristics, characterized by 30% glass fiber reinforced PES resin, its coefficient of linear expansion is only 2.3x10-5 / ℃, and up to 200 ℃ is still able to maintain a similar value with aluminum.
6, Impact resistance, with the same impact resistance as the
polycarbonate cool, not reinforced resin can be riveted, but more sensitive to the sharp and thin incision, so in the design must pay attention to!
