Product Overview

Eastman Benzoflex™ 9-88 SG is a non-phthalate plasticizer for use with cast urethanes. The SG is a "special grade" with a maximum hydroxyl number specification designed for use in polyurethane prepolymers. Benzoflex™ -88 SG offers excellent inert filler acceptance, generally provides wear characteristics, and lowers formulation costs for cast polyurethanes. Eastman Benzoflex™  9-88 SG plasticizer minimizes cure interference and is compatible with both ethers and esters. Benzoflex™ 9-88 SG is recommended for polyurethane formulations, such as machine rolls, printing rolls, and more.
