Product Summary
Dibutyl Sebacate (DBS) is a diester plasticizer produced from sebacic acid and butanol. As a low-molecular-weight ester, it offers excellent compatibility with PVC, cellulose resins, and synthetic rubbers. This product is widely used in toys, PVC products, plastics, leather, ink, and food packaging applications. With an ester content of at least 99.0%, low acidity, and low moisture, it ensures stable processing and superior finished product performance. Being phthalate-free, it is an eco-friendly alternative for sensitive applications.
Key Features
- High Purity: Ester content ≥99.0% ensures consistent plasticizing efficiency and final product quality.
- Phthalate-Free: Suitable for toys, food packaging, and other applications with strict safety regulations.
- Low Acidity & Moisture: Max 0.10 mgKOH/g acidity and max 0.10% moisture prevent unwanted reactions and improve stability.
- Excellent Softening Effect: Enhances elasticity and reduces cracking in PVC leather, films, and sheeting.
- Good Low-Temperature Flexibility: Maintains flexibility in cold environments, ideal for outdoor and cold-chain applications.
