1) Traditional protective film: such as galvanized steel protective film, color steel protective film, glass plate or plastic sheet protective film. Such traditional protective films are mostly applications with low added value, low performance and crystal point requirements, and mostly rubberized protective films.
2) Protective film for flat panel display: Applications include flat panel displays, TFT-LCD modules, backlight modules, glass substrates, and various optical components such as polarizers and color filters. Such protective films have extremely high requirements for viscosity and crystal point control, and are applications of high added value and high technology thresholds.
3) Protective film for high-tech electronics: such as the protective film used in Dry Film or wafer polishing processes. Such protective films usually need to be produced in a clean room, and the requirements for the crystal point are extremely severe. Only a handful of protective film manufacturers have sufficient technical capabilities to meet these requirements.
