In terms of building materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging films, bottles, foaming materials, sealing materials, and fibers, PVC was the world`s largest production of general-purpose plastics, and its applications are very widely. Widely used in all aspects.
PVC is a white powder with an amorphous structure. The degree of branching is relatively small. The relative density is about 1.4. The glass transition temperature is 77~90°C. It begins to decompose at about 170°C. It has poor stability to light and heat. After prolonged exposure to sunlight, it will decompose to produce hydrogen chloride, and further automatically catalyze the decomposition, causing discoloration, and the physical and mechanical properties also rapidly decline. In actual applications, stabilizers must be added to improve the stability of heat and light.
the Degree of polymerization of SG5 is 1000. usually we also call PVC Resin S1000. Its K-value is K67.
According to reports, South Korea's president-elect Lee Myung-bak’s power handover team announced that South Korea’s energy policy will be transformed from the previous participation in and investment in a potential gas field into a direct purchase of an overseas company with proven reserves from Korea Gas Commune.
In the first half of 2007, Korea’s oil and natural gas self-sufficiency rate was 3.8%. The South Korean government plans to increase this ratio to 28% by 2016.
According to insiders, this "positive" acquisition is likely to happen, and the relevant parties are studying the specific gas fields to be acquired. Another policy expert said that the South Korean government will also promote the participation of Korean Gas Commune and other enterprises in the development of natural resources in Western Siberia.
Lee Myung-bak will formally take office as President of South Korea on February 25. He once stated that one of the core policies of the new government is to increase the country’s energy self-sufficiency rate in order to ensure the sustainable development of the economy, and his foreign policy will serve South Korea’s participation in overseas resource development.
