General Information

• Product Name: Sodium Poly(naphthaleneformaldehyde)sulfonate
• CAS: 9084-06-4
• Catalog: SUR-AN-024
• Applications: Dye industry, agricultural sector, construction industry, others

Introduction

Sodium poly(naphthaleneformaldehyde)sulfonate, commonly abbreviated as PNFS, is an anionic surfactant. This compound is a condensation product of methyl naphthalenesulfonate and formaldehyde, resulting in a brown powder with unique solubility and stability characteristics. PNFS is widely utilized for its exceptional dispersing properties, particularly in dye formulations and pesticide dispersions.

Characteristics

PNFS is distinguished by several key characteristics essential for its applications:

• Appearance: PNFS is a brown powder.
• Solubility: The compound is highly soluble in water, making it suitable for aqueous solutions and formulations.
• Chemical Stability: PNFS exhibits remarkable stability in acidic, basic, and hard water environments.
• Dispersing Ability: One of the standout features of PNFS is its excellent dispersing ability. It enhances the uniform distribution of particles in suspensions, which is particularly beneficial in dye formulations.
• Thermal Stability: PNFS maintains its structural integrity and functionality even at elevated temperatures. This thermal stability is essential for processes that involve high-temperature conditions, such as dyeing and textile treatments.
• Compatibility: It shows good compatibility with other anionic and non-ionic surfactants, allowing it to be used in combination formulations to meet specific industrial requirements.
• Affinity: PNFS has a high affinity for proteins and polyamide fibers, making it an ideal choice for textile applications. However, it exhibits no affinity for cotton and linen fibers, which allows for selective application.

Applications

PNFS finds applications in the following aspects due to its versatile properties:

Dye Industry

• Dispersant for Dyes: PNFS is extensively used as a dispersant in vat dyes, disperse dyes, and reactive dyes. Its excellent dispersing properties ensure uniform color distribution and enhance the grinding efficiency, resulting in higher color yield. For instance, in the production of disperse dyes, PNFS prevents the aggregation of dye particles, ensuring a stable and consistent dye solution.
• High-temperature Dying: Compared to other dispersants like dispersant N, PNFS offers superior high-temperature resistance, making it suitable for dyeing processes that require elevated temperatures.

Agricultural Sector

• Pesticide Formulations: PNFS is employed as a dispersant in wettable pesticide formulations. Its ability to maintain stable dispersions in water ensures that the pesticides remain effective and evenly distributed when applied, enhancing their efficacy.

Construction Industry

• Water-Reducing Agent: In the construction sector, PNFS serves as a water-reducing agent in cement formulations. It improves the workability of concrete and reduces the water content required, leading to stronger and more durable concrete structures.

Packaging and Storage

• Packaging Options: Typically packaged  in 25kg bags, customizable according to customer requirements.
• Storage Conditions: Stored in a cool, dry place away from direct sunlight and heat sources to maintain the compound's integrity and efficacy.
