NEOPTSA, also known as N-Ethyl O/P Toluene Sulfonamide, is a versatile sulfonamide plasticizer used in polyamide resins, printing inks, coatings, adhesives and other polymer systems. |
NEOPTSA is a mixture of N-ethyl ortho-toluenesulfonamide and N-ethyl para-toluenesulfonamide. Its balanced plasticizing performance and compatibility make it a practical choice for formulations requiring improved flexibility and processing performance.

| CAS number: | 8047-99-2 |
| Typical use: | Plasticizer and functional additive |
Polyamide resin films may become relatively hard or brittle under certain formulation and environmental conditions. NEOPTSA can help reduce brittleness and improve film flexibility.
NEOPTSA has good compatibility with many alcohol-soluble and co-solvent polyamide resin systems. Appropriate dosage and formulation testing can help produce a uniform and stable product.
When used at a suitable dosage, NEOPTSA may contribute to smoother film formation and improved resistance to cracking. It can also help the film retain flexibility after drying.
NEOPTSA can help formulators balance hardness, flexibility, adhesion and processing behavior. Laboratory compatibility testing is recommended before commercial production.
★ Polyamide resin modification
★ Gravure and flexographic printing inks
★ Coatings for flexible substrates
★ Industrial adhesives
★ Plastic and polymer modification
★ Nail lacquer and specialty coatings
★ In printing ink formulations, NEOPTSA is often used together with polyamide resin to improve film flexibility and reduce brittleness. Actual performance depends on the resin grade, solvent system, pigment content, substrate and application conditions.
Formulation note:The appropriate dosage should be determined through laboratory testing. Excessive addition may affect hardness, drying or blocking resistance, while insufficient addition may not provide the required flexibility. |
NEOPTSA should be stored in a cool, dry and well-ventilated place. Keep the packaging tightly closed to prevent moisture absorption and contamination.
Users should consult the latest Safety Data Sheet before handling the product and follow appropriate industrial hygiene and personal protection procedures.
