|  | Vinyl compounds become progressively more rigid as temperature decreases. To overcome this low temperature effect formulators have two options:
- Add progressively more plasticizer to maintain flexibility at low temperature
- Switch in part or completely to a more efficient plasticizer.
The first option is attractive until problems with compatibility or plasticizer exudation negatively impact product performance. The second option is attractive if the concept of efficiency is understood and the formulator is experienced in low-temperature applications.
There are several Jayflex plasticizers commonly used to address low-temperature performance requirements. Jayflex DINP and Jayflex DIDP are readily accepted for use in low-temperature applications. For more severe conditions, Jayflex L11P and Jayflex DTDP work well. The most severe conditions are met with Jayflex DINA and Jayflex DIDA. They provide the low temperature flexibility and permanence that is required.
The following figures show the effect Jayflex plasticizer type and concentration have on the compound low temperature properties.
