K-FLEX® 500 Non-Phthalate Plasticizer

K-FLEX® 500 is a dibenzoate plasticizer that optimizes the excellent performance of K-FLEX® DP with improved handling, due to its low temperature flexibility. K-FLEX 500 is a very cost-efficient plasticizer that brings value to applications such as waterborne adhesives, hot melt adhesives, and latex caulks.

As a high solvating plasticizer, K-FLEX 500 offers excellent compatibility with polymers such as PVC or polyvinyl acetate, resulting in an impressive balance of performance and economy.
