Packaging and shipping
Polypropylene Glycol, abbreviated as PPG, is a colorless, odorless, non-toxic viscous liquid with excellent stability, lubricity and water solubility. It is a polyether compound produced by polymerization of propylene oxide, with different molecular weights available to meet various industrial demands. It features good compatibility, low volatility, high thermal stability and anti-oxidation properties, making it widely used in cosmetics, polyurethane, coatings, lubricants and chemical industries.
In cosmetics and personal care, PPG acts as an effective moisturizer, emollient and dispersant, improving skin feel and product texture without irritation. In polyurethane production, it serves as a key raw material for foam, elastomers and sealants, providing excellent flexibility and durability. It is also widely used as a lubricant, anti‑foaming agent, plasticizer and solvent in industrial fields.
PPG is safe, environmentally friendly and easy to use. It should be stored in a cool, dry and sealed condition, away from strong oxidants. With stable performance and high purity, it is a high-quality raw material widely applied in many industries around the world.
Product Description
Polypropylene Glycol (PPG) is a high-purity, synthetic polyether polyol derived from the polymerization of propylene oxide.
It is a clear, colorless, and nearly odorless viscous liquid with excellent hydrophobicity, low volatility, and high thermal stability.
PPG exhibits outstanding solubility in organic solvents and good compatibility with various polymers, resins, and surfactants.
It is non-toxic, non-irritating, and chemically inert, making it suitable for diverse industrial applications. PPG is typically supplied in sealed,
moisture-proof steel drums or IBC tanks (200L/1000L) to ensure product stability and prevent contamination.
All packaging meets international transportation and storage standards, guaranteeing safe handling and long-term quality preservation.
PPG is a versatile chemical widely used in polyurethane production, lubricants, surfactants, and personal care products. In the polyurethane industry,
it serves as a key raw material for flexible foams, elastomers, and coatings, enhancing flexibility, durability, and weather resistance. As a lubricant and anti-wear agent,
PPG reduces friction in mechanical systems and hydraulic fluids. In cosmetics and personal care, it acts as a humectant, emollient, and solvent,
improving product texture and skin compatibility. Additionally, PPG functions as a defoamer, emulsifier, and chemical intermediate in textile, paint, and plastic industries.
Its unique properties and eco-friendly characteristics make PPG an indispensable material in modern manufacturing.
