PES material bottle will become the main force in the future bottle market

Upon examination, PES does not contain bisphenol A, an estrogenic suspicious substance. Therefore, PES can be called the most ideal bottle material at present. At the same time, the PES bottle has the advantages of non-toxic glass bottle, transparent, light and unbreakable PC bottle. Based on the above advantages, PES as a high-performance type of plastic materials, has gradually replaced the PC milk bottle in the developed regions of Japan, Europe and the United States to become the mainstream of the market. It is expected that the PES bottle will gradually become popular in China's infant bottle market.

A polyethersulfone resin (PES) is a comprehensive performance in 1972 the British company ICI excellent in developing a thermoplastic polymer material, it is applied to one of the few special engineering plastics having excellent heat resistance, Physical and mechanical properties, insulation properties, and the like have particular advantages in that they can be used continuously at high temperatures and can maintain stable performance in environments where the temperature is drastically changed, and have been widely used in many fields.

Bottles made from PES resin as raw materials usually have the following characteristics: First, they are safe, and they are approved by the US FDA in terms of hygiene standards; Second, they are high temperature resistant, and the heat-resisting temperature of PES is as high as 220°C. It can be repeatedly boiled and steam sterilized. , The hospital vacuum autoclave, microwave oven heating and disinfection and liquid disinfection; Third, hydrolysis resistance, resistant to 150 ~ 160 °C hot water or steam, at high temperatures are not affected by acid and alkali; Fourth, dimensional stability, The coefficient of linear expansion is small, and the reliability of temperature is also small. Fifth, impact resistance, PES has the same impact resistance as polycarbonate (PC), and six is ​​flame retardant, self-extinguishing, without adding any flame retardant. Excellent flame resistance; Seven is chemical resistance, PES is resistant to gasoline, oil, lubricants and other oils and Freon cleaning agent, its solvent resistance cracking is the best among the amorphous resin. But its resistance to acetone, chloroform and other polar solvents is not good performance, the need to pay attention when using; eight is the durability, the general service life is 3 to 4 times the ordinary PC bottle, the actual cost is lower than the PC; nine is no pigment Add, the honey color of the PES bottle is the original natural color of PES, no added any color material, also represents the highest quality color.
