K-FLEX® DP

K-Flex DP is dipropylene glycol dibenzoate, which is one of the oldest members of the plasticizer family and one of the most versatile polar plasticizers still commercially available.  K-Flex DP is compatible with a wide range of polar polymers and rubbers and is often blended with other plasticizers such as K-Flex DE (diethylene glycol dibenzoate).
