PEG with different molecular weight has different kinds of physical form. The appearance changes with molecular weight from thick liquid (Mn=200~700), waxy semisolid (Mn=1000~2000) to hard waxy solid (Mn=3000~20000).

Frequently Asked Questions (FAQ)
How does molecular weight affect the physical form of PEG?
The appearance of PEG transitions with molecular weight: low molecular weight PEG (Mn=200~700) is a thick liquid, intermediate weight (Mn=1000~2000) is a waxy semisolid, and high molecular weight (Mn=3000~20000) appears as a hard waxy solid.
What are the recommended storage conditions for this material?
It should be stored in a cool, dry, and well-ventilated place with containers kept tightly closed. The recommended storage temperature range is between 2 - 8 °C.
What is the standard storage stability or shelf life?
According to the technical specifications, the standard storage period is greater than or equal to 1 year under compliant conditions.
Is this product regulated for transportation?
No, transport information indicates that this product is not regulated as a hazardous material for shipping.
Can alternative or customized specifications be ordered?
Yes, while the published technical parameters serve as standard reference values, alternative specifications are welcome for further discussion based on application needs.
