Polyethylene glycol 2000 is a medium-to-high molecular weight PEG. Due to its longer molecular chain, it is used in coating systems to enhance the flexibility and weather resistance of the coating. EG2000 has a higher molecular weight and a more significant toughening effect, making it suitable for industrial coatings with high requirements for impact resistance and bending resistance. PEG1500 has better compatibility and is commonly used in water-based architectural coatings and anti-corrosion coating systems.

Application areas
|
1. Food Industry
|
It is commonly used as an emulsifier, thickener, anti-crystallization agent, stabilizer, and humectant, increasing the viscosity and stability of food and improving its taste, texture, appearance, and stability. In baked goods, it prevents ice crystal formation and extends the product's freshness. Furthermore, in sauces, condiments, and gravies, it acts as a thickener and preservative, giving products a smooth, creamy texture and inhibiting the growth of bacteria and fungi.
|
|
2. Beverage industry
|
As an antifoaming agent, it solves the foaming problem in beer and soft drink production.
|
|
3. Manufacturing
|
As a coolant and antifreeze, it lowers the freezing point of the liquid and prevents the cooling system from freezing. It is commonly used in automobiles, industrial equipment, and air conditioning systems to ensure that the liquid can still flow under cold conditions.
|
|
4. Pharmaceutical manufacturing industry
|
As a solvent, diluent, and carrier for drug delivery systems, it can be used in the preparation of drugs and medical products.
|
|
5. Daily chemical industry
|
It is used as a wetting agent and consistency regulator, and is often used in products such as creams, lotions, toothpaste, shaving creams, and detergents. It is also suitable for non-rinsing hair care products, giving hair a silky shine.
|
|
6. Industrial Manufacturing
|
It can be used as an additive, diluent, or surface treatment agent in fields such as lubricating oil, coatings, paints, pulp, and textiles.

Stability and storage conditions
Store in a cool, dry place, avoiding direct sunlight. Polyethylene glycol is a flammable liquid; therefore, fire safety regulations must be followed during storage and handling. Keep away from open flames.
