Core Definition and Structure
Basic Composition: Formed by bonding two or more sheets of glass together with one or more layers of organic polymer interlayers; the assembly is permanently fused through high-temperature pre-pressing and high-temperature, high-pressure processing.
Common Interlayers: Mainstream materials include PVB, SGP, EVA, and PU, with different materials offering specific functional advantages.
Key Characteristics
Safety and Injury Prevention: Upon breakage, fragments adhere firmly to the interlayer rather than scattering as sharp shards, thereby eliminating the risk of lacerations.
Impact and Burglary Resistance: Capable of withstanding repeated blows from weapons such as hammers or knives; specialized products can even resist bullet penetration for a short duration, offering robust protection against theft and intrusion.
Sound and UV Insulation: Blocks "coincidence noise" in the 1000–2000 Hz range and filters out over 99% of ultraviolet radiation, protecting indoor furnishings and human skin.
Energy Efficiency: Absorbs heat from the infrared spectrum and reduces solar transmission, thereby lowering energy consumption for indoor cooling.
