01Technical introduction
DBP (Di-N-Butyl Phthalate): overview
DBP (di-n-butyl phthalate) is a lower-molecular-weight phthalate plasticizer with a specific gravity of 1.041 to 1.0455 at 27 °C and a G.C. ester content of 99.5 % minimum. It is typically used in blends with other plasticizers and in formulations where fast fusion or solvating power is useful.
Superior Plasto Chem publishes the full characteristic table for DBP, with test methods, so it can be placed beside DOP and odourless DOP when a technical team is selecting a plasticizer package.
Benefits
- Published 99.5 % minimum G.C. ester purity.
- Low moisture (0.1 % max) and acid value (0.01 % max).
- Colour 20 Hazen units max, including after heat treatment at 180 °C for 2 hours.
- Supplied alongside DOP and chlorinated paraffin, so a blended system can be sourced from one supplier.

Technical data sheet (TDS), certificate of analysis (COA) and safety data sheet (SDS) availability depends on the grade and source. Ask for the documents you need when you request a quote and we will confirm what can be supplied for your order.
05Storage and handling
Storage and handling
- Store in tightly closed, clean and dry containers, away from direct heat, sunlight and ignition sources.
- Keep away from strong oxidisers, strong acids and bases; keep containers off bare ground and clear of drains.
- Use dedicated, clean transfer equipment to avoid cross-contamination and moisture pick-up.
- Follow the safety data sheet (SDS) for personal protective equipment, spill response and disposal.
General good-practice guidance. The safety data sheet for your supplied grade always takes precedence.
06Applications
Where DBP is used
| Application | Note |

08FAQ
DBP: frequently asked
How does DBP differ from DOP in specification?
DBP has a higher specific gravity (1.041 to 1.0455 against 0.980 to 0.986), a higher refractive index, and a published ester purity of 99.5 % minimum against 99 % minimum for DOP.
Can DBP be used on its own in PVC?
It is more commonly used in blends. Final selection depends on your formulation, processing and end-product requirements; test in your own compound.
Do you have restrictions on where DBP can be used?
DBP is restricted in several markets and product categories. Please confirm the requirements for your product and destination before ordering.
