3.Uses
| Propylene glycol is mainly used for surface coating and glass fiber reinforced unsaturated polyester resin (UPR). It's second largest application is antifreeze, instead of ethylene glycol used in antifreeze aircraft and used as a coolant in the food. It can be used in the production of plasticizer and hydraulic brake fluid. It also can be used as nonionic detergents and as a moisturizer in medicine,cosmetics,animal food and tobacco industry.In addition ,PG can be used for printing ink and epoxy resin, etc.as a good performance of solvent . |
4.Packing and Transport
Packing: In iron drums with zinc inside; 210±0.5kg/drum, Packed in TANK, ISO TANK or on the client's requirements.
Storage: store in a cool, dry, well-ventilated area away from incompatible substances. Store protected from moisture.
