Table 1: Comparison of cold temperature performance of ExxonMobil’s Jayflex L9TM plasticiser against L810TM. Formulation comprised PVC 100phr, plasticiser 50phr , calcinated clay 12phr, Sb2O3 4phr, stearic acid 0.2phr. Cold flexibility performance assessed by Clash-Berg method to ASTM D 1043-84 and Bell brittleness temperature to ASTM D 746

for example, meeting automotive cable Class C requirements (3000h 125°C),” he says. In contrast to some of the more linear plasticis-


ers, which exhibit a phase transition (cold crystal- lisation followed by melting), Jayflex L9TM exhibits no crystallisation peak around 0°C. It displays cold temperature properties similar to those of a linear trimellitate of similar average molecular weight, such as L810TM (Table 1). Discussing the use of trimellitates in PVC plasti-


sols, Naert says that to fulfil the plastisol spread coating requirements in terms of production output, adequate plastisol viscosity and gelation is required. “The use of trimellitates in PVC plastisols results in a substantial increase in the process temperature required over general-purpose plasticisers to reach the final gelation. L9TM, combining branched and linear structures exhibited similar gelation tempera- tures as L810 TM.” See Figure 2. JayflexL9TM is now registered under REACH and will be commercially available in Europe, North America and Asia Pacific. “With the introduction of Jayflex L9TM, ExxonMobil continues to develop its already wide range of high molecular weight plasticisers for PVC,” Naert says.
