Performance & Applications
💊 Pharmaceutical Preparations
PEG series are versatile excipients for pharmaceutical dosage forms:
- Solvents & Stabilizers: Lower-MW PEGs for aqueous suspensions, emulsions, and injections.
- Drug Carriers: Serves as a carrier for solid dispersions to improve the solubility of poorly water-soluble drugs.
- Ointment & Suppository Bases: Used as water-soluble bases for consistent drug delivery.
- Coating & Capsules: PEG 4000/6000 are excellent for hydrophilic polishing, film-forming, and capsule materials.
PEG-200
Industrial: Organic synthesis medium, heat-transfer fluid, and humectant in daily chemicals.
Textile & Paper: Softener, antistatic agent, and wetting agent for pesticides/papermaking.
PEG-400, 600, 800
Cosmetics: High-performance vehicles and humectants.
Metal & Rubber: PEG-600 enhances grinding performance and surface gloss in metal electrolytes; lubricants for rubber processing.
PEG-1000, 1500
Coatings & Inks: Dispersants for resins (20–30% dosage); adjusts ink viscosity and reduces volatility in stamp-pad/ballpoint inks.
Rubber: Promotes vulcanization and acts as a dispersant for carbon black fillers.
PEG-2000, 3000
Metal Processing: Mold release agents, wire drawing lubricants, and cooling fluids.
Paper Industry: Lubricants and hot-melt adhesives to improve rapid re-wettability.
High MW Grades (4000, 6000, 8000)
Pharmaceuticals: Bases for viscosity and melting point adjustment.
Papermaking: Coating agents to increase gloss and smoothness.
Rubber & Metal: Extends service life by improving plasticity and cooling efficiency.
Pesticides & Pigments: Highly effective dispersants and emulsifiers.
