In the realm of polymer science and manufacturing, plasticizers are indispensable additives that imbue materials with essential properties like flexibility, processability, and durability. Dibutyl Sebacate (DBS), identified by CAS No. 109-43-3, is a highly effective and versatile plasticizer, particularly recognized for its excellent performance in low-temperature applications. For professionals involved in polymer compounding, extrusion, and molding, securing a reliable supply of high-quality DBS is crucial. As a leading DBS plasticizer supplier based in China, we are committed to offering superior Dibutyl Sebacate and competitive pricing, making us your ideal partner for procurement.

Dibutyl Sebacate is a diester of sebacic acid and n-butanol, appearing as a clear, colorless liquid. Its primary function is to reduce the intermolecular forces within polymer chains, thereby lowering the glass transition temperature (Tg) and enhancing the material's flexibility. A standout characteristic of DBS is its exceptional performance at low temperatures; it maintains its plasticizing efficiency when exposed to cold, preventing polymers from becoming brittle or cracking. This property makes it invaluable for polymers used in applications that experience wide temperature variations or operate in cold climates.

Key Polymer Applications Benefiting from Dibutyl Sebacate

The versatility of DBS allows it to be incorporated into a wide range of polymer systems, delivering enhanced performance:

  • PVC and Vinyl Compounds: DBS is widely used in flexible PVC formulations for applications such as films, sheets, cables, and hoses. It improves their pliability, impact resistance, and importantly, their performance in low-temperature environments.
  • Synthetic Rubbers: In the compounding of synthetic rubbers, DBS acts as a plasticizer to improve processability, reduce hardness, and enhance low-temperature flexibility. This is critical for seals, gaskets, and other rubber components used in automotive and industrial equipment.
  • Cellulosics and Acrylics: DBS can also be used to plasticize cellulose derivatives and acrylic polymers, enhancing their flexibility for use in coatings, adhesives, and specialized plastic components.
  • Specialty Polymers: Its robust performance characteristics make it suitable for more demanding polymer applications, including those found in aerospace and defense, such as plasticizers for solid propellants.
