Product Feature

Propylene glycol is the raw material of plasticizers, surfactants, emulsifiers and demulsifiers.

 - High Purity and Stable Quality

Polykem supplies high-purity Propylene Glycol for customers who need stable material performance in regular production. Before shipment, product quality can be checked against agreed specifications, including appearance, purity, moisture and acidity. For applications such as resin production, cosmetic formulations or industrial processing, consistent PG quality can help reduce unnecessary adjustment during use.

 - Good Solubility and Compatibility

Propylene Glycol is easy to mix with water, alcohols and many common organic solvents. This makes it useful in liquid formulations where ingredients need to dissolve, disperse or remain evenly distributed. In many applications, PG works not only as a solvent, but also as a carrier or humectant, especially in personal care products, industrial fluids, coatings and antifreeze-related systems.

 - Multiple Grades Available

Different applications may require different grades of Propylene Glycol. Polykem can supply PG for industrial, food, pharmaceutical, cosmetic and resin-related uses, depending on the customer’s target application and specification needs. Related documents such as COA, MSDS and TDS can also be provided when required.

 - Stable Supply and Flexible Packaging

For customers with trial orders or regular procurement plans, Polykem can provide flexible supply support for Propylene Glycol. Packaging can be arranged in drums, IBC tanks or bulk shipment according to order quantity and delivery requirements. For overseas orders, the team can also assist with packaging confirmation, export documents and shipment coordination.
