FAQ
Q: What is the main function of PEG4000 in rubber?
A: The core functions are lubrication and demolding, assisting in the dispersion of fillers, reducing processing friction, and improving production efficiency and rubber quality.
Q: Is there any difference compared to other PEG models (such as PEG6000)?
A: PEG4000 has a moderate melting point and better fluidity, making it more suitable for rubber mixing and processing. PEG6000 has a higher hardness and is more suitable for demolding applications.
Q: What should be noted when storing and using it?
A: Store it sealed in a cool and dry place, away from high temperatures, and avoid melting and caking; before mixing, it can be crushed in advance to facilitate dispersion.
