Flexible PVC Plasticizers | DOTP, DINP, ESBO Bulk Supply

Plastificantes para PVC Flexível (Dureza Shore / Sem Ftalatos)

Compostadores de PVC flexível e de borracha dosam ésteres plastificantes por IBC e isotanque para solvatar a resina e atingir a dureza e a flexibilidade a baixa temperatura desejadas. Muitos estão migrando ativamente dos orto-ftalatos (DEHP/DBP) para o DOTP não ftálico e para ESBO e citratos de base biológica, a fim de atender REACH, CPSIA e requisitos de contato com alimentos

Abordagem de solução

RawSource supplies the base chemicals that go into these programs. We can help with product selection, grade matching, and sourcing from multiple origins for supply security.

Typical Formulation Workflow

Polymer & Process Definition

Identify the resin and process (extrusion, molding, film) and the targets — thermal stability, clarity, flame retardance, slip, or color.

Additive Selection

Match stabilizers, antioxidants, plasticizers, lubricants, flame retardants, or masterbatch carriers to the polymer and processing temperatures.

Compounding Trial

Confirm loading and dispersion on a compounding or molding trial, checking processability, mechanicals, and aesthetics against the control.

Validation & Scale-Up

Verify long-term performance (heat aging, migration, weathering) and lock the formulation, packaging, and lot specs for production.

Epoxidized Soybean (ESBO)

CAS 8013-07-8

Aditivos Especiais

Emoliência

Bio-based secondary plasticizer and co-stabilizer; the epoxide rings scavenge HCl liberated during PVC processing while adding flexibility

Citrate-ester non-phthalate plasticizer used where regulatory-sensitive, food-contact-grade flexibility is required

Physical Description: practically colourless, oily liquid; bitter tas… Appearance: Colorless, mobile liquid Odor: Fruity odor
