In the field of architecture, acrylic is breaking through the physical limits of traditional glass. The skylight of Beijing Daxing Airport is made of 8cm thick cast panels, with a light transmission loss rate of only 8%, which is 42% more energy-efficient than glass of the same thickness. The observation deck of Shanghai center Building uses bulletproof acrylic, whose impact resistance is 20 times that of ordinary glass, and can withstand the impact of Level 12 typhoon. In terms of innovative applications, the light guide plate system of the Hangzhou Asian Games swimming pool achieves a standard deviation of less than 5lux for the water surface illumination of the pool through the uniform refraction of LED light sources by acrylic. In the residential field, the acrylic sound barrier of a high-end real estate project, combined with a hollow structure, reduces traffic noise by 35 decibels. The self-cleaning coating on the surface restores the light transmittance to 98% after rainwater flushing.
