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.
According to the roadmap for the phase-out of incandescent lamps in China issued by the five ministries and commissions such as the National Development and Reform Commission five years ago, starting from October 1, 2016, China will ban the import and sale of ordinary lighting incandescent lamps of 15 watts or more. In the face of policy adjustments, in recent years, first-line lighting companies have vigorously promoted energy-saving lamps and LED bulbs to replace incandescent lamps. However, due to some leeway left during the release of the road map, whether the import and sale of transparent glass-case incandescent lamps is completely banned will be adjusted according to the mid-term evaluation results. Therefore, it is expected that the relevant state departments will issue new ones when the 11th arrives this year. The policy will further clarify the elimination measures for incandescent lamps in the future. It is understood that since the phasing out of the roadmap for incandescent lamps in China, from various levels of government to first-line lighting companies, through government subsidies, discounts, gifts and other forms, vigorously promote energy-saving lamps and LED bulbs in the community. The data shows that since 2011, the cost of domestic LED lighting enterprises has been decreasing, and the popularity of LED lamps has been increasing. From less than 10% in 2011 to 32% in 2015, the replacement of incandescent lamps with LED lamps is the general trend. Industry insiders predict that after China's total ban on the use of ordinary lighting incandescent lamps of 15 watts and above, China's urban lighting will usher in a wave of replacement LED lights in 2016, LED light source lighting will usher in another 100 billion market. In the short term, the market for LED candle lamps and LED filament lamps will be further opened, continuing the procurement boom of related products in the European and American markets, including LED filament lamps and small wattage LED candle lamps, 0.5 watt, 1 watt, 2 watt specifications. It can replace 15W to 30W incandescent lamps, and 40W, 60W to 100W incandescent light sources will be replaced by the mainstream LED bulb market. There are fewer people buying energy-saving lamps now, and many young people buy LED lights when they decorate new homes. Mr. Huang, a shopping guide for a decorative materials city lighting city in Nan'an Road, Liwan District, Guangzhou, told. On the other hand, according to industry insiders, in the process of promotion, energy-saving lamps have been widely criticized for their prices higher than incandescent lamps and virtual power consumption. Since 2013, they have been included in the “Semiconductor Lighting Industry Energy Conservation Planâ€. "The LED bulbs of the promotion products are also subject to many bottlenecks in the promotion due to the problems of high price, inability to fume, and less applicable lamps.
