This glass product was researched and developed independently by Xiangtan Kaisheng New Materials Technology Co., Ltd. It can absorb rays selectively from the Sun and filter over 90% of the harmful ultraviolet rays and near infrared rays, which makes over 70% of the visible light through, so as to keep warm in winter and keep cool in summer; this new product can be used to the front windshield of automobiles and trains, and the windows and curtains of buildings.
The company successfully developed the UV-IR absorbent by the ultra heat-absorbing glass technology, in which the reversible principles in photochemistry and photophysics are applied and the compound of quencher and deactivator is used. If such UV-IR absorbent is added to the composition of unorganic glass and organic glass or various kinds of resin optical films with a proper proportion, the thermal insulation materials (paint) and the laser wave protective products of varied types that can absorb ultraviolet rays and near infrared rays can be made. Such glass can also be processed for various purposes, such as tempering, hot bending, laminating, bulletproof and heat insulation etc. In addition, it can also be used for protection from laser wave in the field of national defense for military purpose.
