+Glass Industrial Autoclaves are pressure vessels used to process glasses and polymer materials which require exposure to elevated pressure and temperature. The manufacture of high-performance components from advanced composites often requires autoclave processing.
+Vacuum
Parts processed in an autoclave are often silicone vacuum bagged to enable the pressure to operate isostatically on the workpieces. In simplest form, the workload is fully contained inside a loosely fitting silicone bag made of resilient plastic capable of withstanding the temperatures involved. When vacuum is drawn, the bag is compressed by atmospheric pressure and compacts the components inside. Between the parts and the bag, an absorbent material provides a channel for the evacuation of the air and wicks up the excess resin squeezed out during curing.
+In autoclave processing of composite parts, the SILICONE vacuum bag functionality may be where the greatest variety may be found. Some manufacturers will leave the bag under full vacuum from lay-up to post-cure tear-down. Others will hold the silicone vacuum bag only until the autoclave reaches full pressure. Yet others will back-fill the silicone vacuum bag with inert gas, typically nitrogen, at zero pressure.The role played by the silicone vacuum bag’s internal pressure can be critical in the consistent production of high-quality PVB Laminated Glass.
+Polyvinyl butyral (or PVB) is a resin often adopted for applications that require strong binding, optical clarity, adhesion to many surfaces(organic or non organic sheets), toughness, great tensile strength and flexibility. It is prepared from polyvinyl alcohol by reaction with butyraldehyde. The major application is laminated safety glass for automobile windshields. Tradenames for PVB-films include GlasNovations, Butacite, Saflex, S-Lec, CNCnext and Trosifol.
+Laminated glass is a type of safety glass that holds together when shattered. In the event of breaking, it is held in place by an strong polymer interlayer, typically of polyvinyl butyral (PVB) or EVA Film, between its two or more layers of glass. The PVB interlayer keeps the layers of glass bonded even when broken, and The high strength of cross-linked PVB interlayer prevents the glass from breaking up into large sharp pieces. This produces a characteristic “spider web” cracking pattern when the impact is not enough to completely pierce the laminated glass.
+There are several laminated glass manufacturing processes:
-using two or more pieces of glass bonded between one or more pieces of plasticized polyvinyl butyric resin using heat and pressure .
-using two or more pieces of glass and polycarbonate, bonded together with aliphatic urethane interlayers under heat and pressure.
-interlaid with a cured resin.
Each manufacturing process may include glass lites of equal or unequal thickness.

+Bent Laminated Glass:
When making Bent laminated glass with Polyvinyl Butyral PVB film, like car windshield glass, car windows etc, you will need silicone bag for vacuuming. Bent and curved glass is often used for automotive glass and marine glass installations.
