SGP film (SGP diaphragm) has higher application advantages in the construction field, and the industry has huge room for growth.

SGP film, also known as SGP diaphragm, refers to a type of translucent diaphragm prepared by mixing polyethylene terephthalate and metal salt ions. SGP is an ionic interlayer membrane. It is a new polymer material that uses ionic bonds as a binding method and has high molecular weight and high elastic modulus. SGP film is one of the three common adhesive materials used in manufacturing laminated glass. The other two types of adhesive materials are mainly PVB film and EVA film.

According to the“2023-2028 SGP Film (SGP Diaphragm) Industry Market In-depth Research and Investment Prospect Forecast Analysis Report” released by the Industrial Research Center shows that the production process of SGP film is similar to that of PVB film, but it has higher shear modulus (up to more than a hundred times that of PVB film), tear strength (up to five times that of PVB film), load-bearing Strength (up to more than twice that of PVB film), etc.

Therefore, laminated glass prepared using SGP film has better mechanical properties, durability, edge stability, anti-theft and explosion-proof properties, impact resistance, UV resistance, and good permeability, transparency, water resistance, and weather resistance. safety, and can be widely used in automobiles, construction, photovoltaics and other fields. In addition, SGP film can also be used to prepare ultra-white laminated glass, which has broad application prospects.

SGP film has higher application advantages in architectural laminated glass due to its good characteristics. Specific application scenarios include architectural glass curtain walls, ceiling glass, bank glass, stair glass, etc. In recent years, with the increasing market penetration of architectural glass curtain walls, SGP film has shown great development prospects. However, due to factors such as incomplete relevant standards and high prices, the SGP film consumer market is mainly concentrated in foreign regions such as Europe and the United States, and there is limited room for development in the Chinese market.

SGP film was first developed and produced by DuPont in the United States. After continuous research and development, many companies in my country have overcome key technologies and achieved mass production of SGP film. At present, the main domestic SGP film manufacturers include Dongguan Qun’an Plastic Industry, Suzhou Jingdun Glass Technology, Fujian Hongbaoxin Plastic Technology, Anhui Angu Hi-Tech, Foshan Yien Film Technology, Guangdong Fushengbang New Materials, and Chongqing Huakai Plastic wait. As the advantages of domestic SGP film products such as high cost performance, strong technology and short supply cycle continue to be highlighted, local companies are accelerating to occupy the global market share, and the industry has broad prospects for development.

Industry analysts said that SGP film is one of the main bonding materials for laminated glass. Laminated glass also has advantages that are difficult to replace. At present, SGP film is mainly used in the construction field. It is a key raw material for the production of glass for building glass curtain walls, ceilings, and glass planks. The market shows great development prospects. However, due to price and standard factors, there are still relatively few applications of SGP film in my country. In the future, local companies will need to continue to study ways to reduce product costs and increase efficiency and participate in and promote the establishment of industry standards. The industry has huge room for growth.
