Dibutyl Phthalate (DBP) is a fast-fusing plasticizer widely used in flexible PVC, adhesives, sealants, printing inks, and nail polish. Its high compatibility and plasticizing efficiency make it especially suitable for applications that require quick gelation and flexibility at low temperatures.

Q1: Is DBP banned in some regions?
Yes, DBP is restricted in some applications (e.g. toys, food contact) due to regulatory rules. Check local guidelines befoPackagere use.
Q2: Can DBP be used with non-PVC systems?
Yes. It works well in adhesives, rubber, nitrocellulose, and coatings.
Q3: Is DBP considered fast-fusing?
Yes. It is widely used in plastisols for its excellent fusion behavior.
