): The board is a high-quality board made of polycarbonate as the main component and using co-extrusion technology. Because its surface is covered with a layer of high-concentration ultraviolet absorbers, it not only has anti-ultraviolet properties, but also remains weather-resistant for a long time and will never fade. The board connection can be connected with special Zhengcheng enterprise glue to effectively prevent leakage.
br ): (Polycarbonate) has high mechanical strength, extremely high impact toughness and high glass transition temperature, as well as heat resistance and non-deformation ability, and the working temperature range is from sub-zero degrees to degrees.
Features: High mechanical strength, good creep resistance, very high impact strength even at low temperatures, rigidity retention over a wide temperature range, good resistance to energy rays, good electrical insulation, very good dimensional stability Translucent and physiologically inert, suitable for contact with food.
Applications: instrument inspection panels, piping systems, safety glass, writing pads, slide projector equipment components, widely used in machinery, electronics, automobiles, construction, daily necessities and other fields, and is rapidly expanding to aviation, aerospace, Electronic computers, optical discs, optical fibers and many other high-tech fields.
