K-FLEX® DP Non-Phthalate Plasticizer

K-FLEX® DP is a dibenzoate plasticizer and one of the most versatile polar plasticizers still commercially available. It has excellent compatibility with a wide range of polar polymers and rubbers and is often blended with other plasticizers. K-FLEX DP is a high solvator and delivers value to many applications, but it is particularly recommended for coatings, such as nitrocellulosic and acrylic lacquers, and vinyl applications, such as plastisol printing.

Similar to K-FLEX PG, K-FLEX DP has an extremely low freeze point, which results in easier handling.
