SGP film (SGP diaphragm) has a higher application advantage in the construction field
Date:2023-08-18
SGP film, also known as SGP film, refers to a kind of semi-transparent film prepared by mixing polyethylene terephthalate and metal salt ions. SGP is an ionic intermediate membrane, which is a new polymer material with high elastic modulus and high polymer bond. SGP film is one of the three common bonding materials for the manufacture of laminated glass, and the other two types of bonding materials are mainly PVB film and EVA film.
According to the "2023-2028 SGP film (SGP diaphragm) industry market in-depth research and investment prospects forecast analysis Report" released by the New Thought Industry Research Center, SGP film production process is similar to PVB film, However, it has a higher shear modulus than PVB film (up to 100 times more than PVB film), tear strength (up to five times more than PVB film), and bearing capacity (up to two times more than PVB film).
Therefore, the laminated glass made of SGP film has better mechanical properties, durability, edge stability, anti-theft and explosion-proof performance, impact resistance, anti-ultraviolet performance and good permeability, transparency, water resistance, weather resistance, safety, and can be widely used in automotive, construction, photovoltaic and other fields. In addition, SGP film can also be used to prepare ultra-white laminated glass, which has a broad application prospect.
SGP film has a higher application advantage in architectural laminated glass with good characteristics, the specific application scenarios include architectural glass curtain wall, ceiling glass, bank glass, stair glass and so on. In recent years, under the background of increasing market penetration rate of architectural glass curtain wall, SGP film has shown great development prospects. However, due to the imperfect standards and higher prices, the SGP film consumption market is mainly concentrated in Europe, the United States and other foreign regions, and the market development space in China is limited.
SGP film was first developed and produced by DuPont in the United States, and after continuous research and development, there are a number of enterprises in China to overcome key technologies to achieve mass production of SGP film. At present, the domestic SGP film production enterprises mainly include Dongguan Qunan Plastic Industry, Suzhou Jingdun glass material Technology, Fujian Hongbaoxin Plastic technology, Anhui Angu High-tech, Foshan Yi En film technology, Guangdong Fusheng Bang new materials, Chongqing Huakai Plastic and so on. With the advantages of domestic SGP film products with high cost performance, strong technology and short supply cycle, local enterprises are accelerating to occupy global market share, and the development prospects of the industry are broad.
Industry analysts said that SGP film is one of the main bonding materials for laminated glass, and there are difficult to replace advantages in ultra-white laminated glass. At present, SGP film is mainly used in the field of construction, and is the key raw material for the production of glass for building glass curtain walls, ceilings and glass walkways, and the market has shown great prospects for development. However, limited by price and standard factors, China's SGP film applications are still relatively few, the future of local enterprises need to continue to study product cost reduction and efficiency ways and participate in promoting the establishment of industry standards, the industry growth space is huge.
