In recent years, with the economic level of ascension and consumption upgrade, promote the electronic product upgrades, user experience in material, appearance, and so on multi-dimensional, at the same time, in the high-end, intelligent, personalization, differentiation, lightweight, material durability, energy efficiency, green environmental protection, the development direction for the protection of consumers, has brought profound changes to people's production and life.
Many enterprises began to use new materials, new design and new technology, to improve the performance of electrical and electronic products and enrich the appearance of products, product innovation and improvement.
From the point of material breakthrough homogenization competition, has become a number of electrical and electronic enterprises "sunflower treasure dian", especially in the fierce competition in the mobile phone industry.
In 2018, the global smartphone market sales decline, 5G technology is seen as the last resort.Some analysts say that the world will usher in 5G mobile phone replacement wave in 2020.With the improvement of 5G's functional requirements for mobile phone products, mobile phone materials are facing higher challenges and performance requirements.5G, not only brings revolution to the mobile phone industry, but also opens an era of opportunities for new materials.Among them, mobile phone antennas made of LCP(liquid crystal polymer) materials are very promising.
LCP is an aromatic thermoplastic polyester, which has two types: one is lysotropic liquid crystal, which has liquid crystal properties when dissolved in solvent.The other is thermotropic liquid crystal, which has liquid crystal properties when melted.Currently, thermotropic liquid crystal polymers are mainly used in the electronics industry, because LCP has excellent performance for small electronic devices and is mainly suitable for mass production of injection molding.In commercial engineering plastics, LCP has high fluidity, can fill small and thin wall products, high thermal stability in lead-free reflux process, excellent environmental protection and flame retardant, very low water absorption, short molding cycle, low shrinkage and other characteristics.
With the advent of 5G era and rapid penetration of comprehensive screen, the demand for LCP flexible board antenna will be further increased to meet the demand for high-speed and high-frequency transmission and thinness of intelligent terminal products in 5G era.
With 5G brush blast circle of friends and "folding screen"!Samsung, huawei, royole and Nubia have all launched fold-screen mobile phones, making "fold-screen" move from concept to application.2019 will be the first year of the explosion of fold-screen mobile phones, and many areas of components will benefit from it, among which the CPI membrane link associated with plastic processing will usher in new development opportunities.
The foldable cover plate of mobile phone is not only required to be foldable, but also to ensure that it is not easy to scratch.The original glass cover can not meet the requirements of folding, will be eliminated, flexible plastic Colorless Polyimide (CPI) film is expected to become an ideal cover material for folding screen.In the manufacture of CPI, it is necessary to carry out a hard coating process with a thickness of tens of microns on the surface, such as the use of mixed material siloxane, which is expected to make the touch of CPI close to glass, and improve the intensity of CPI.Currently, manufacturers with the mass production capacity of CPI film mainly include cologne industry of South Korea, sumitomo chemical of Japan, SKC of South Korea and other manufacturers.
