Santicizer 278 Plasticizer is a high molecular weight Benzyl Phthalate that offers very low volatility and good permanence, yet retains the aggressive solvating characteristics of the Benzyl Phthalates. High compatibility and low volatility give good processing and permanence that compares with polymeric plasticizers. This unique combination makes it a versatile plasticizer for use in many different resin systems.
In Polyvinyl Chloride (PVC), Santicizer 278 shows low flexibilizing efficiency: yet formulations are fast processing. The end product will be highly resistant to staining and dirt pick-up and will retain its properties well even when exposed to high temperatures, extractants - such as solvents, oils, grease - and other severe-use conditions.
Santicizer 278 has been found to be especially effective in vinyl systems that require extremely good migration resistance. Typical of this effect is the use of Santicizer 278 in automotive sealants. Santicizer 278 provides excellent paintability with "Hi-solids" automotive enamels and resists migration into the paint. |
