Uniplex 214 N-Butylbenzenesulfonamide 3622-84-2 Unitex Chemical Plasticizers Polyamides (PA) ADHESIVE SEALANT NON-WOVEN Insoluble in water 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. Stable N-Butylbenzenesulfonamide. Used as plasticizer for polyamides especially nylon, in adhesives for nonwoven interlinings. Possesses good heat stability to 80°C and promotes easier removal from molds and easier machining. Provides better finish and better shape stability due to reduced water absorption.
