Uniplex 214 (N-Butylbenzene sulfonamide or BBSA) is a liquid sulfonamide plasticizer for a number of resins, such as polyacetals, polycarbonates, polysulfones, and polyamides especially Nylon-11 and Nylon -12. The addition of this plasticizer contributes the following properties:
- Easier removal from molds
- Easier machining
- Better finish
- Good heat stability to 80'C
- Better shape stability due to reduced water absorption
Uniplex 214 is the preferred primary plasticizer for polyamide resins, greatly enhancing low temperature flexibility. Uniplex 214 may be added either pre-or post-polymerization for Nylon-11 or 12, and in the extrusion of other polyamides (e.g. Nylon 6, Nylon 66). It is typically used at levels of 5 - 20%, based on the weight of the polymer.
Uniplex 214 is used in such applications as molded polyamide parts, nylon fishing line, nylon-based adhesives for nonwoven interlinings, auto fuel line, coil air hoses, and other high performance applications. |
