Product Description

 

Product Description

Polyvinyl butyral (or PVB) is a resin which a member of the polyvinyl acetal family. That it is produced by reaction between PolyvinylAlcoholand Butyraldehyde. Polyvinyl butyral (PVB) resin hold on the excellent adhesive and film-forming properties, its strong binding power and its outstanding optical transparency. At presently, main areas of application including interlayer of laminated safety glass, general industrial and wood coatings, varnishes, ink, temporary binders and adhesives and so on.

 
 

Product Application

 

Film Applications

 
- For Automotive and architectural glass
Laminated glass, commonly used in the automotive and architectural fields, comprises a protective interlayer, usually polyvinyl butyral, bonded between two panels of glass. The bonding process takes place under heat and pressure. When laminated under these conditions, the PVB interlayer becomes optically clear and binds the two panes of glass together. Once sealed together, the glass "sandwich" (i.e., laminate) behaves as a single unit and looks like normal glass. The polymer interlayer of PVB is tough and ductile, so brittle cracks will not pass from one side of the laminate to the other.
- Colors PVB for tinted glass
Band Colors PVB interlayer can be used for the blue or green "shade band" at the top edge of many automobile windshields. Full Colors PVB interlayer can also be used in different colors for architectural laminated glass manufacture ranging from Bronze, Gray, Green, Brown, White and many more.
- Solar modules
PVB has gained acceptance among manufacturers of photovoltaic thin film solar modules. PVB and a second sheet of glass (called back glass) are then placed directly on the circuit. The lamination of this sandwich encapsulates the circuit, protecting it from the environment. Current is extracted from the module at a sealed terminal box that is attached to the circuit through a hole in the back glass.
 
 

Non-Film Applications

PVB resins (provided by the manufacturer in powdered or granulated form) are also utilized in a range of applications including technical ceramic (temporary) binders, inks, dye transfer ribbon inks, paints & coatings (including wash primers), binders for reflective sheet and binders for magnetic media. PVB resin is particularly useful at bonding to metals, ceramics and other inorganic substances.
