What This Grade Is For
Hydroxyethyl Cellulose Ether for Metalworking Fluid is supplied by Yiyuantong Chemical as a thickener and lubricity aid in water-based metalworking fluids. HEC is widely used in multiple industries due to its excellent thickening, suspension, moisturizing, solubility, and stability. HEC provides reliable functionality and performance in various application fields, becoming an indispensable component in many products.
Key Benefits
- Raises viscosity so the fluid stays on the tool and workpiece
- Keeps additives and solids suspended in the sump
- Contributes to surface wetting and heat removal in the cut
- Held in stock: 800 tonnes of HEC are carried year round, and confirmed orders ship to the named port within 3 working days
Problems It Solves
- Water-based cutting fluid that will not carry lubricity to the tool edge
- Fluid that separates in the sump between shifts
- Additives that drop out of the concentrate during storage
Application Scenarios
- Water-miscible cutting and grinding fluid
- Drawing and forming lubricants
- Quenching fluids
Who It Is For
- Metalworking fluid formulators
- Lubricant blenders
- Industrial fluid suppliers
Technical Features
- Non-ionic backbone, so viscosity survives salt and hard water
- Cold-water soluble, no cooking step needed in the mixing room
- Supplied from 300 to 200000 mPa.s so the grade can be matched to the process
- Molar degree of substitution of 1.8 to 3.0 for biological stability and high transmittance
- Solvent process raises the degree of substitution by 30 to 35 percent against traditional routes

How It Compares
| Polyalkylene glycol thickeners | Cellulose ether builds viscosity at low addition and is not oil dependent |
|---|---|
| Xanthan gum | Cellulose ether resists the microbial attack that shortens sump life with some biopolymers |
Use Guide

Hydroxyethyl Cellulose Ether for Metalworking Fluid FAQ
Will it affect the biocide package?
Run a compatibility check with your existing package before scaling up; the material itself is used in water-based fluids as a thickener and suspension aid.
What dose is typical?
It is set by the viscosity you want in the concentrate. Send the target and we will propose a grade and starting dose.
Are you a manufacturer or a trading company?
We are a manufacturer and you are welcome to visit the plant. Our hydroxyethyl cellulose project runs at 5000 tonnes a year on an acetone countercurrent washing process.
What payment terms do you accept?
L/C, T/T, D/A, D/P, PayPal and Western Union. We have worked with China Export and Credit Insurance Corporation for many years.
How fast can you ship?
Stock items are despatched within 5 days of payment. If the grade is not in stock, production and despatch take 7 to 10 days from payment.
