Industrial Grade DOP Plasticizer Dioctyl Phthalate Low Dosage For PVC Industry
Dioctyl Phthalate (DOP)
CAS Number: 117-84-0
Molecular Formula: C₂₄H₃₈O₄
Molecular Weight: 390.55
DOP is the most widely used main plasticizer in plastic processing, recognized for its excellent comprehensive performance and reliability in industrial applications.
- High plasticizing efficiency with low dosage
- Excellent compatibility with PVC resin and synthetic rubber
- Good low-temperature flexibility to prevent cracking
- Superior cold resistance, flexibility, and electrical properties
- Colorless transparent liquid without affecting product gloss
- Wide application range for all kinds of PVC products
- Cost-effective and easy to process
Primary Applications:
- Widely used in processing polyvinyl chloride, vinyl chloride copolymers, and cellulose resins
- Manufacturing films, synthetic leather, wire and cable sheets, boards, molded products, and plasticizers
- Softener for synthetic rubber such as nitrile rubber, improving product resilience and reducing compression permanent deformation
Industry Usage: 80-90% of DOP is used in the PVC industry, with additional applications in rubber, recycled plastics, lubricants, adhesives, coatings, polymer additives, printing ink softeners, and capacitor oils.
