Model Number: HY003 Brand Name: HongYu Glass Key Specifications/Special Features: It is produced by permanently bonding two pieces of glass together with tough plastic inter-layer (polyvinyl butyral) under heat and pressureInter-layer material is invisible when viewed through glassWith glass on either side, finished lite is indistinguishable from monolithic glass when installed in a frameMost often, laminated glass is produced from annealed glass, but heat strengthened or tempered can be used when special performance needs are requiredPolyvinyl butyric (or PVB) is a resin usually used for applications that require strong binding, optical clarity, adhesion to many surfaces, toughness and flexibilityIt is prepared from polyvinyl alcohol by reaction with butyraldehydeMajor application is for laminated safety glass for automobile windshields and constructionsIt is a combination of two or more glass sheets with one or more inter-layers of plastic (PVB) or resinIn case of breakage, interlayer holds fragments together and continues to provide resistance to the passage of persons or objectsGlass is particularly suitable where it is important to ensure the resistance of the whole sheet after breakage such as: shop-fronts, balconies, stair-railings and roof glazingProduction:

There are two types of laminated glass: PVB and resin laminated glass

PVB laminated glass is two or more sheets of glass which are bonded together with one or more layers (PVB) under heat and pressure to form a single piece

Resins laminated glass is manufactured by pouring liquid resin into the cavity between two sheets of glass which are held together until the resin cures

Features:

• It is formed as s sandwich of 2 sheets of glass bonded to a tough and thermoplastic polyvinyl butyral (PVB) interlayer
• It is also a safety material against destroy and theft without fragment splashing down when broken

Applications:

• Furniture architecture
• Windows and skylights
