Dioctyl Sebacate (DOS) Plasticizer with Ultra-Low Temperature Resistance

High-performance cold-resistant plasticizer for industrial applications.

CAS: 1222-62-3

Molecular Formula: C₂₆H₅₀O₄

Molecular Weight: 426.66

Dioctyl Sebacate (DOS) is a premium excellent cold-resistant secondary plasticizer widely recognized for its outstanding stretching efficiency, ultra-low volatility and remarkable long-term thermal stability. Integrated with balanced heat resistance, light stability and reliable electrical insulation performance, it delivers far more comprehensive low-temperature ductility than ordinary cold-resistant plasticizers such as DOA. Compatible freely with PVC, nitrocellulose, ethyl cellulose and all kinds of synthetic rubber, it serves as a highly versatile auxiliary additive that is absolutely essential for manufacturing all kinds of high-performance, weather-resistant synthetic materials with strict cold resistance requirements.

• Superior Ultra-Low Temperature Resistance: Keep products flexible under extreme cold conditions
• Low Volatility Performance: Less weight loss and long service life at high processing temperature
• Balanced Comprehensive Stability: Combine heat resistance, light resistance and electrical insulation
• Wide Resin Compatibility: Match PVC, nitrocellulose, ethyl cellulose and all synthetic rubber
• Rubber Friendly Characteristic: No negative impact on rubber vulcanization process
• Flexible Compound Formula: Can be mixed arbitrarily with DOP, DOTP and other phthalate plasticizers
• Food Safe Grade: Approved for meat preservation film and food contact packaging materials
• Multi-Scenario Applicability: Ideal for cold cable, artificial leather, conveyor belts and plastic sheets

Dioctyl Sebacate (DOS) is a premium cold-resistant auxiliary plasticizer featuring excellent stretching efficiency, ultra-low volatility and outstanding long-term stability. It delivers outstanding low-temperature flexibility, while also possessing reliable heat resistance, anti-ultraviolet light performance and superior electrical insulation. It boasts great compatibility with multiple thermoplastic materials, including polyvinyl chloride, nitrocellulose, ethyl cellulose and all types of synthetic rubber.

This plasticizer is the top choice for manufacturing cold-proof wire and cable insulation, food-safe meat wrapping films, premium artificial leather, plastic films, industrial conveyor belts, rigid plastic boards and flexible sheets. Manufacturers commonly blend DOS with phthalate main plasticizers to achieve balanced product performance and cost control.

When adopted as a low-temperature softening additive for synthetic rubber products, DOS will not interfere with the rubber vulcanization reaction or damage finished rubber properties.
