- What is polyvinyl butyral (PVB)?
- Polyvinyl butyral (PVB) is a polymer for highly demanding applications. It is characterized by its optical clarity, toughness, flexibility and excellent adhesive properties with many materials such as glass, metal, plastics and wood. Due to these properties, PVB is mainly used for laminated safety glass..
- Can tetraethylene glycol Di-n-heptanoate be used as a plasticizer for PVB?
- Although it is known, according to U.S. Pat. No. 4,230,771 to use tetraethylene glycol di-n-heptanoate as a plasticizer for PVB, the other diesters derived from acids having a carbon chain of 7 or more carbon atoms are generally slightly or not at all compatible with PVB.
- What is the plasticizer content of PVB resin?
- Although the quantity of plasticizer used can vary as a function of the plasticized PVB properties that are desired, the plasticizer content of the PVB-plasticizer is preferably between about 10 and 65%. The plasticizing of the PVB resin may be carried out by any standard method known in the art.
