Polyester polyols are the important raw materials of coating, adhesives, elastomer and foam.
No mater aromatic polyols or aliphatic polyols, we can provide the special products according to customers` requirement.
Polyester polyol is a type of polyol that is derived from the reaction between a polyol (such as glycerol or ethylene glycol) and a dicarboxylic acid (such as adipic acid or phthalic anhydride). It is commonly used as a raw material in the production of polyurethane foams, coatings, adhesives, and elastomers.
Polyester polyols have several advantages over other types of polyols. They have good chemical resistance, mechanical properties, and thermal stability. They also have low toxicity and are environmentally friendly. Additionally, polyester polyols can be easily modified to achieve desired properties, such as increased flexibility or flame retardancy.
Polyester polyols are typically liquid at room temperature and have a high molecular weight. They can be further reacted with isocyanates to form polyurethane materials, which have a wide range of applications in various industries, including automotive, construction, and furniture.

1 Information Technology Electronic measuring instruments, digital multimeter annual output of 7 million units, is 80% of the world's total output, exports to 96 countries in the world, ranking first in the world; other such as spectrum analyzers, digital power supplies, oscilloscopes, etc. Both are at the leading level in China.
2 Medical instruments (such as nuclear magnetic resonance, Doppler Doppler, and gamma knife) have taken the lead in the country, and the substitution of imports has saved the country a lot of life.
3 automated instrumentation and control systems and ancillary equipment.
4 office automation equipment and equipment.
5 Intelligent three-meter (electricity, water, gas) intelligent, remote remote control and its computer management system, electrical instrumentation and power meter calibration equipment.
6 industrial control machines, material testing machines.
7 Building automation, warehouse automation, etc., are in a leading position in the country.
From the point of view of the entire industry, it has come out of the stage of processing, component assembly and OEM production. The company's products are being networked to the computer interface, intelligent high-end, create their own brand name, self-designed, for foreign markets, and strive to create a nationwide World production base.
However, it should be noted that as time goes on, with the continuous deepening of the domestic comprehensive open reform, the predecessor and unique advantages of the SAR have become increasingly weak. The advantages of the region adjacent to Hong Kong have also become more and more softened, and companies have directly linked to the international market.
To make the instrumentation industry continue to develop at a rapid pace must be C charging. One of them allows companies to follow the path of industrial park conglomeration. When companies sprint on foreign markets, in addition to technological upgrading, the most difficult one is that the scale of the company is not large enough, the capital is not strong enough, it is the same as splurge, it is the output value of billions of dollars. The enterprises in the international market, but also the company of 1-2 million US dollars, not a big company, so can not get a higher platform, there is no analog advantage, so it is bound to take the science and technology industrial park and the group of the way.
Polyester polyols can be divided into aromatic polyols and aliphatic polyols because of the acid and polyols.
Aromatic polyols are mostly used in preparing PU rigid foam which foam has great thermal insulation ability.
Aliphatic polyols with different raw materials show different performance.
Enterprise Informationization Drives Instrumentation Modernization
Shenzhen's instrumentation industry under the leadership of the municipal government, with the advantages of Dongfeng and its neighboring Hong Kong, has become the R&D base and product import and export base of China's instrumentation industry in South China after more than ten years of rapid development. Its concrete embodiment is:
