Santicizer 148 Plasticizer is an efficient flame retardant, excellent for many commercial resins, particularly Polyvinyl Chloride and its copolymers, Polyvinyl Acetate and Acrylics. It is high solvating and provides good low-temperature flexibility, and it is miscible with most common solvents.
Santicizer 148 imparts flame retardance, low-temperature flexibility and low volatility in Polyvinyl Chloride. It can replace DOP part-for-part to the level needed for fire retardancy while maintaining the flexibility and the softening efficiency of that phthalate. Its use in the compound imparts low smoke generation performance that is far superior to Triaryl Phosphates or Antimony Oxide. It also offers superior fusion properties and solvating action and imparts resistance to abrasion, oil and grease. Used as a 10%-15% replacement for phthalates, it imparts excellent weather and light stability. Hand and drape of the finished film or coated fabric containing Santicizer 148 are outstanding.
In vinyl plastisols, Santicizer 148 exhibits fast fusion, low initial viscosity and moderate viscosity stability. Cell structure of vinyl foams is excellent. Clear formulations show a sparkling clarity with Santicizer 148. The cured compound possesses good low-temperature flexibility and flame retardance. |
