Chlorinated polyethylene is a saturated polymer material with a white powder appearance. It is non-toxic and tasteless. It has excellent weather resistance, ozone resistance, chemical resistance and aging resistance. It has good oil resistance, flame retardancy and coloring properties. It is an excellent impact modifier for PVC plastics and a synthetic rubber with good comprehensive performance. It has a very wide range of applications and has been widely used in cables, wires, hoses, tapes, rubber and plastic products, sealing materials, flame retardant transport belt , Waterproof coiled material, film and various profiles and other products.
As a PVC impact modifier, CPE135A has many advantages such as low price, excellent performance, and excellent aging resistance, but it has certain disadvantages in the use of high impact and high hardness products and low temperature resistant products CPE135A. For example, in the formulation of rigid PVC, a large amount of CPE will reduce the hardness and rigidity, which reduces the physical properties of the product; in addition, when the low temperature resistance requirement of PVC products exceeds minus 30°C, CPE135A cannot meet the requirements. Under normal circumstances, modified CPE, such as ACM, RGC135A, etc., can be selected for rigidity and hardness improvement; for low-temperature resistance modification, impact-resistant ACR or other impact modifiers with lower glass transition temperature can be selected.

The LED lighting industry is one of the strategic emerging industries in China's 12th Five-Year Plan. The industry is developing very rapidly, and the application market potential is huge. Due to the lack of standardized and standardized optical components and lighting standards, it poses severe challenges to the development of the entire industry. At the same time, it also restricts the healthy development of the LED lighting industry to a certain extent.
In recent years, Jinke Electronics has introduced a flip-chip gold-free chip-scale package device that creatively combines flip-chip bonding technology with gold-free chip-scale packaging, with more stable performance, better heat dissipation, and more uniformity. Light color distribution and smaller volume are favored by more and more LED lighting companies and terminal product application companies. So what is the gold-free package?
In integrated circuit packaging technology, the connection of the wafer electrode to the bracket pins is generally achieved by interconnecting gold wires, but gold wire breakage has been one of the common causes of failure. With the introduction of flip-chip bonding technology, the connection between the two can be connected by a more stable metal bump solder ball, eliminating the gold wire, greatly improving its reliability and heat dissipation. Flip-chip soldering technology has also been used in LED packaging technology, LED has a long life and other advantages, with the flip-chip soldering technology than the traditional gold wire interconnect packaging technology can give full play to the advantages of LED, known as gold-free package . At present, the representative enterprise that can maturely apply this technology is Jingke Electronics.
The birth of new technology is always accompanied by doubts. What are the advantages of non-packaging technology? What opportunities and challenges will it bring to the midstream enterprises? Can non-packaging technology become the new standard in the LED industry?
