performance
1.Safety : laminated glass can keep whole while broken and no injure to people. It is called safety glass same as tempered glass. 2.Strength for resistance to impact : can withstand impact of 1040g steel ball without broken by free dropping at 1.2m height. 3.Strength for resistance to human body : can withstand impact of 45kg ( 100 pounds ) simulated human body without penetration. 4,Optical performance : it depends on raw glass material . The transmittance of laminated glass is in direct proportion with raw glass. 5.Stability for resistance to environment : laminated glass can withstand irradiation of sunlight for long- term and basically no change under high moisture and hot conditions.
