Polyethylene Glycol (PEG-2000) Functions & Its Essential Role in Metalworking

Polyethylene Glycol (PEG-2000): An Essential Solution for Precision Metalworking

As industrial standards advance, quality demands in metal processing have become increasingly stringent. PEG-2000 has emerged as an indispensable raw material to address critical challenges:
✔ Surface imperfections
✔ Thermal deformation during cutting
✔ Tool wear reduction

This versatile additive delivers triple-action performance:

1. Lubrication – Minimizes friction for smoother machining

2. Cooling – Prevents heat-induced material distortion

3. Anti-corrosion – Provides in-process rust protection

Technical Specifications
