Proviplast® 1783 is a well-known plasticizer for polyvinylbutyral (PVB) films, used extensively in laminated glass. It imparts low temperature performance, low volatility and improved plasticization.

Proviplast® 95XP is an effective plasticizer for polar and semi-polar rubbers with very high purity and low VOC.
