Product Description

Product Overview: Polyether NPE-105

Polyether NPE-105 (CAS 37251-69-7), a nonionic alkylphenol ethoxylate propoxylate ether, excels as a low-foam, low-temperature fluid surfactant. It functions as a core component in textile oil agents, dyeing auxiliaries, detergents, and antistatic textile additives. Boasting good compatibility and stable performance, it serves industries like textiles, dyeing, and cleaning—ideal for enhancing emulsification, penetration, and processing efficiency in various formulations.

Product Advantage

Excellent Compatibility & Solubility
It dissolves in water without swelling (unlike most surfactants), ensuring stable blending in formulations. Its neutral pH (5.0–7.0) avoids reacting with other ingredients, making it suitable for diverse chemical mixes.
Low Foam & High Efficiency
With foam levels lower than general surfactants, it prevents foam buildup in industrial processes (e.g., dyeing, cleaning). Its HLB value (11–12) balances emulsifying and dispersing abilities, boosting processing efficiency by 15% in textile applications.
Superior Low-Temperature Fluidity
Maintaining fluidity at low temperatures (cloud point 38–44℃), it performs reliably in cold environments—critical for regions with low ambient temperatures or cold-storage processing.
Multi-Functional Performance
It integrates emulsification, antistatic, and wetting functions: as a fiber oil agent component, it reduces static by 20% while enhancing fiber lubrication; in dyeing, it improves color uniformity by 10%.

Product Uses

Textile Industry
As a component of synthetic fiber oil agents, it provides emulsification and antistatic protection, reducing fiber friction and static buildup during spinning and weaving. It also enhances fiber processing smoothness.
Dyeing & Printing Industry
Used as a leveling, dispersing, and wetting auxiliary, it ensures uniform dye distribution on fabrics, prevents color spots, and improves dye penetration—ideal for cotton, polyester, and blended fabric dyeing.
Industrial Cleaning
Its strong penetration and cleaning abilities make it suitable for industrial equipment cleaning (e.g., textile machinery), removing oil stains and residues without damaging surfaces.

Product Operate Guide

For general applications: Dilute Polyether NPE-105 with water (ratio 1:5–1:20, depending on use case). Stir evenly before adding to formulations (e.g., fiber oil agents, dye baths). Avoid mixing with strong acids/bases. Store in a cool, ventilated area; seal the container after use to prevent contamination.

FAQ

What is the shelf life of Polyether NPE-105?
It has a 2-year shelf life when stored in sealed packaging in a cool, dry, and ventilated place (avoid direct sunlight and moisture).
Can it be used with other surfactants?
Yes. Its neutral pH and good compatibility allow blending with most nonionic/anionic surfactants—test small batches first to ensure stability.
Is it suitable for food-contact applications?
No. Polyether NPE-105 is designed for industrial use (textiles, dyeing, cleaning) and is not intended for food, cosmetic, or medical applications.
