Our company has been deeply involved in the field of insulation materials for many years, continuously expanding our product matrix with advanced technology reserves. Now, we have formed a product matrix of new energy materials+optical film materials (biaxial stretching)+electronic resin materials (monomer synthesis)+environmentally friendly flame retardant materials, corresponding to emerging growth tracks such as AI / integrated circuits / new displays / new energy / photovoltaics / automotive decoration downstream.
The main product of our company’s optical film industry is optical grade polyester base film (optical PET base film), which is one of the most important strategic materials at the forefront of the optoelectronic industry chain. At present, the company’s leading products include brightening film base film, bonding film base film, OCA release film base film, ITO high-temperature protection film base film, MLCC release film base film, polarizer release film base film, window film base film, automotive functional film, etc. The process technology is mature and the performance indicators are becoming increasingly stable. At the same time, the company actively expands its coating products such as reducing film, flexible panel functional tape, OLED process protective film, etc., relying on its own technological reserves and advantages in industrial chain integration, further extending its industrial chain into the field of OLED flexible display.
Optical film is one of the most important strategic materials at the forefront of the optoelectronic industry chain. Optical film is an optical medium material composed of thin layered media uniformly attached to the surface of optical devices. It utilizes the physical properties of light waves such as reflection, transmission, and polarization when propagating light beams at interfaces to achieve effects such as reflection, anti reflection, splitting, filtering, or changing the polarization state of light beams, thereby meeting the optical functions required by people. Our company applies to optics
The main product of the film material industry is optical grade polyester base film, mainly made of polyester chips as the main raw material.
Optical grade polyester base film is mainly used in light sources, automobiles, electronic displays, and IT industries. As a high-end functional film material, it has excellent optical properties such as low haze, low shrinkage, high clarity, high transmittance, and high surface smoothness, with high technological content and added value. The products are mainly divided into optical grade protective film, diffusion film, brightening film, composite film, hardening film, touch screen insulation and explosion-proof film, OCA film, polarizer release and protective film, ITO film, flexible solar cell, electromagnetic screen and IMD/IML, etc.
Our company has multiple specifications of optical base films that can meet your needs. If you would like to learn more about our products, please contact our email sales@dongfang-insulation.com.
