Special Functional Optical Clear Adhesive (OCA)
Textured Polycarbonate Film
Description
Kaixin optical grade polycarbonate (PC) film is light and thin, ultra-transparent and clear, excellent printing ability and optical properties. Its light transmittance can reach more than 91%, and the transmittance in the ultraviolet band is very low. The crystal points and concave and convex points are strictly controlled to eliminate impurities, foreign matter, scratches and other defects. It has built-in insulation properties and is an ideal hardening and plating material. At the same time, its physical properties are also extremely excellent, showing excellent impact resistance, scratch resistance, heat resistance and weather resistance. Optical-grade PC films have stable physical properties and can operate in harsh environments, so they are widely used.
The manufacturing process and performance requirements of optical grade PC films are very high. In the manufacturing process, advanced stretching technology is used. By continuously stretching the PC material, its crystal lattice is ordered, making it more transparent, optically better, and more stable than ordinary PC films. In terms of physical properties, PC materials need to be upgraded and improved to have higher heat distortion temperature and strength.
For the field of graphics and text printing, Kaixin film performance characteristics: excellent weather resistance, temperature resistance and excellent impact strength, strong pattern adhesion, diverse colors, good flexibility, never fade, and good wear resistance. It has wide applicability, long service life, easy processing, strong temperature adaptability, and has a variety of standards and performance levels to choose from in different application fields.
Features
- High transparency: Polycarbonate (PC) film has high transparency, with a transmittance of more than 90%. It is an excellent light-transmitting material and can be used to manufacture optical devices, liquid crystal displays, etc.
