The market for laminated glass products is mature. With only minor modifications, the PVB interlayer sold today is essentially identical to the PVB sold 30 years ago. Since its introduction in 1938, the worldwide market for PVB interlayer has been dominated by a handful of large chemical companies.
Laminated glass fails due to the cohesive failure of the interlayer and/or the connectivity between the panel and interlayer. [27] The failure of the interlayer can occur when the interlayer material is ductile (at room temperature), or brittle and stiff (when working below the glass transition temperature).
318 Monsanto St., East St Louis, Il. Solutia Inc. was an American manufacturer of materials and specialty chemicals including polyvinyl butyral (PVB), ethylene vinyl acetate (EVA), and thermoplastic polyurethane (TPU) interlayers for laminated glass, aftermarket window films, protective barrier and conductive films, and rubber processing chemicals.
The interlayer can also give the glass a higher sound insulation rating. There are several types of laminated glasses manufactured using different types of glass and interlayers which produce different results when broken. Laminated glass that is made up of annealed glass is normally used when safety is a concern, but tempering is not an option ...
Composite glass is the collective term for a laminate having at least two glass panes which are in each case connected by means of an adhesive intermediate layer composed of plastic, e.g. by means of a casting resin or a thermoplastic composite film, which is highly tear-resistant and is viscoelastic. Composite glass should not be confused with ...
The PVB recycling process is a simple procedure of melting and reshaping it. One possible method of recycling of simple automotive laminated windshields could involve heating the windshield to above the melting point of the PVB interlayer and then separating the glass plies.
It has a density of 1.17–1.20 g/cm 3, [1] [16] which is approximately half that of glass, which is generally, depending on composition, 2.2–2.53 g/cm 3. [1] It also has good impact strength, higher than both glass and polystyrene, but significantly lower than polycarbonate and some engineered polymers.
ICE 3 train with view into driver's cab ICE 3 train with glass panel switched to "frosted" mode. Eureka Tower in Melbourne has a glass cube which projects 3 m (10 ft) out from the building with visitors inside, suspended almost 300 m (984 ft) above the ground. When one enters, the glass is opaque as the cube moves out over the edge of the building.
