ProFlex toluenesulfonamide and benzenesulfonamide grades that plasticize polar resins general-purpose plasticizers cannot soften well. For polyamide, adhesives, inks, and amino, epoxy, and PU systems.
Sulfonamide plasticizers solve a problem general-purpose plasticizers struggle with: softening polar, hard-to-plasticize resins like polyamide, cellulose acetate, shellac, and amino resins. The same polarity that lets them work into those resins gives the finished coating or adhesive good resistance to oils and greases. That is the reason these grades hold a steady place in inks, adhesives, and resin systems.
A clear liquid that plasticizes polyamide and cellulosic resins and works as a dye solvent and pigment dispersant. Low solubility in petroleum hydrocarbons suits grease- and oil-resistant coatings and adhesives.
A liquid plasticizer for polyamide and cellulose, used in nylon, hot-melt and rubber-latex adhesives, printing inks, and surface coatings. Gives low-temperature flexibility, mold release, and low water absorption.
The parent amide, a solid, used in melamine-formaldehyde and urea-formaldehyde laminates and as a reactive plasticizer in epoxy, polyurethane, and melamine systems. Its N-H can react into the cured network.
A harder sulfonamide resin modifier, supplied as a solid and as a solution.
Two of these grades, the N-ethyl and N-butyl monomers, are non-reactive plasticizers that sit in the polymer and lower stiffness. The ortho/para amide is different: its N-H can condense into amino resins and consume isocyanate in polyurethane systems, so it can become part of the cured network. When you formulate with the reactive grade, account for that functionality in the system rather than treating it as inert. We can provide formulation support.
We stock the ProFlex sulfonamide grades in North American warehouses and ship across the United States, Canada, and Mexico. Samples typically go out the same business day, with direct container shipments for commercial volumes. Cross-references to commonly specified sulfonamide plasticizer grades are available on request.
It depends on the grade. The N-ethyl and N-butyl monomers are non-reactive liquid plasticizers. The ortho/para toluenesulfonamide grade is reactive: its N-H reacts into amino, epoxy, and polyurethane systems.
Polar resins that general-purpose plasticizers struggle with, including polyamide and nylon, cellulose acetate, shellac, and amino resins, plus use in hot-melt and PVAc adhesives and printing inks.
For polar resins and the oil-and-grease resistance sulfonamides provide, they fill a role phthalates do not. For non-phthalate food-contact PVC, ATBC is the better-documented choice. The two cover different jobs.
