NPE-108
Jienuo
Polyether NPE-108 (CAS 37251-69-7), a nonionic alkylphenol ethoxylate propoxylate ether, is a versatile industrial auxiliary. As a low-foam surfactant & emulsifier, it excels in stabilizing emulsions, enhancing dispersion, and boosting fluidity (even at low temperatures). Widely applied in textiles (as oil agent/antistatic auxiliary), dyeing, and detergents (as penetrant), it offers excellent compatibility with various formulations. Its high activity and adaptability make it a cost-effective choice for multiple industrial sectors.
Product Advantage
Superior Compatibility & Stability
It dissolves quickly in water without flocculation, maintaining stable performance across pH 5.0-7.0. Its nonionic nature ensures high compatibility with other additives, reducing formulation conflicts—ideal for complex industrial recipes.
Low-Foam & Efficient Performance
As a low-foam surfactant, it avoids excessive foam in production processes (e.g., dyeing, cleaning). Its HLB 10-11 balances emulsification and wetting, boosting processing efficiency by 20% in textile oil agent applications (tested in 100+ customer cases).
Excellent Low-Temperature Fluidity
With a cloud point of 30-35°C, it remains fluid in low-temperature environments, eliminating blockages in storage/transport—critical for cold-region industrial operations.
Multi-Functional Versatility
It integrates emulsification, wetting, antistatic, and dispersing properties, replacing 2-3 single-function additives in formulations, cutting 15% of raw material costs for customers.

Product Uses
Textile Industry
As a component of synthetic fiber oil agents, it provides antistatic properties and low-temperature fluidity, ensuring smooth fiber processing. It also acts as an antistatic auxiliary, reducing static buildup during textile production.
Printing Industry
Serves as a leveling, spreading, and wetting agent in printing, improving ink uniformity and penetration—enhancing print quality and reducing material waste.
Detergent Sector
Works as a penetrant in detergents, boosting the cleaning efficiency of stubborn stains by improving liquid penetration into fabric fibers.
Add Polyether NPE-108 directly to the formulation (dosage: 1-5% of total mass, adjusted by application). Stir at 25-30°C for 5-10 minutes until fully dissolved. Avoid mixing with strong acids/bases (pH beyond 5.0-7.0 may reduce stability). Store in a dry, ventilated area (shelf life: 2 years).
FAQ
What's the shelf life of Polyether NPE-108?
It has a 2-year shelf life when stored in sealed packaging in dry, ventilated conditions (avoid direct sunlight and moisture).
Can it be used in high-temperature processes?
Its cloud point is 30-35°C; avoid using at temperatures above 40°C, as this may affect its stability and performance.
What's the recommended dosage?
The typical dosage is 1-5% of the total formulation mass, but it can be adjusted based on specific application needs (e.g., 2-3% for detergents, 3-5% for textile oil agents).
