PVB means PolyVinyl Butyral which was developed in the early 1930’s and has been produced ever since by a select group of manufacturers worldwide. PVB resin is a non-toxic, non-corrosive product. It has excellent characteristics of transparence, insulation, film-forming properties, impacting resistance and drawing performance.
It has good tensile strength, adhesiveness, elasticity, and is free from inorganic and aliphatic acids. It also owns combination properties of light-proofness, freezing and aging resistance, etc.
PVB resin is not dissolvable in water but is soluble in organic solvents, such as alcohols, esters, ketones, benzene, and in mixed solvents like for example ethyl alcohol and aromatic hydrocarbons.
