Dibutyl Sebacate DBS Primary Plasticizer Heat Resistant Anti Migration For PVC Films
CAS: 53306-54-0
Chemical Formula: C₂₈H₄₆O₄
Molecular Weight: 446.6624
DPHP is a premium high-performance primary plasticizer widely utilized as a core additive in the mass manufacturing of polyvinyl chloride (PVC) plastic products. Engineered with an advanced molecular structure, this plasticizer significantly enhances the inherent flexibility, tensile extensibility, and softness of PVC resin base materials while strengthening structural stability and long-term service durability.
- Superior Thermal Stability: Heat-resistant for long-term high-temp PVC use
- Ultra-Low Volatility: Low weight loss & anti-fogging for auto interiors
- Premium Insulation: High resistivity to meet cable electrical standards
- Anti-Migration: Avoid additive bleed and extend product life
- Wide Polymer Compatibility: Mix well with PVC, rubber, DOP & DINP
- Good Weather Resistance: Stable UV performance for outdoor PVC films
- Efficient Plasticization: Strong softening with small dosage
- Anti-Leaching: Resist extraction from water and soap liquid
Mainly used in the production of wires and cables, automotive interiors, artificial leather, waterproof oilcloth, automotive chassis sealing materials, coil coatings, advertising films, and related applications.
