CAS No: 84-74-2 · HS Code: 2917.12
DBP (Dibutyl Phthalate, CAS 84-74-2) is an efficient general-purpose phthalate plasticiser widely used in PVC compounding, cellulose nitrate lacquers, printing inks, adhesives, and rubber applications across UAE and Saudi Arabia manufacturing. DBP's low molecular weight provides excellent solvating power and strong plasticising efficiency — making it the standard plasticiser for nitrocellulose systems, cellulose acetate, and flexible PVC applications where high compatibility and strong gelation are the primary requirements.

Nitrocellulose Lacquers & Wood Finishes
DBP is the preferred plasticiser for nitrocellulose lacquers used in furniture finishing across UAE and Saudi Arabia manufacturing. Provides excellent flexibility and adhesion to wood substrates — essential for furniture exported from UAE free zones.
Printing Inks — Gravure & Flexo
Used in gravure and flexo printing inks for the UAE packaging industry — DBP imparts film flexibility and adhesion to plastic substrates, preventing cracking in flexible packaging.
PVC Compounding
Efficient primary plasticiser for flexible PVC compounds, cables, and flooring products manufactured across UAE industrial zones. Lower cost per unit plasticiser effect vs DINP in small-scale applications.
Adhesives & Sealants
Plasticiser in solvent-based contact adhesives, pressure-sensitive adhesives, and polysulphide sealants used across UAE and Saudi Arabia construction industry.
Rubber Formulations
Processing aid and secondary plasticiser in synthetic rubber compounds for industrial applications across the GCC.
In nitrocellulose lacquers: 15–30% DBP on resin solids. In flexible PVC: 20–50 phr depending on required flexibility. Note: DBP is classified as a Substance of Very High Concern (SVHC) under REACH (reproductive toxicity, Category 1B). For European export markets, DINP (CAS 68515-48-0) or DINCH (CAS 166412-78-8) are preferred alternatives. For UAE and Saudi Arabia domestic production, DBP remains commercially used but SASO and regulatory trends are toward restriction of SVHCs. Contact Raykem for alternative plasticiser recommendations where REACH compliance is required.
Store in sealed drums at 5–35°C away from direct sunlight and oxidising agents. Flash point 171°C — standard storage. Shelf life: 24 months. Good humidity tolerance.
