Diethylene glycol dibenzoate

Diethylene glycol dibenzoate (CAS 120-55-8) is a synthetic diester plasticizer commercially available under trade names including K-Flex DE, Flexol 2GB, Benzoflex 2-45, Benzoflex 2-42, and Benzoflex S-45. It carries no assigned E-code and is classified under HS code 29163100.

In PVC and polyurethane formulations, it functions as a primary plasticizer by intercalating between polymer chains to reduce glass transition temperature and improve flexibility at low temperatures. In water-based adhesives and sealants, it also acts as a coalescing agent, lowering the minimum film formation temperature to support uniform film development.

This material is supplied as a liquid and is subject to REACH registration requirements within the EU. It is available in standard industrial drum and IBC packaging. Procurement teams should confirm supplier documentation for REACH compliance, SDS availability, and any application-specific purity specifications prior to ordering.
