Polypropylene glycol PPG-400 is chemically stable under normal use conditions, but operational problems that may be encountered in actual operation mainly include: product moisture absorption leading to excessive water content, increased viscosity due to low temperature during storage or transportation, formula delamination or turbidity caused by poor compatibility with other raw materials, and occasional leakage or contact accidents. For different problems, first conduct self-inspection based on the product SDS and the data provided on this page. For example, if the viscosity is abnormal, check the storage temperature (recommended 0–40°C). If the product freezes, it should be naturally returned to room temperature and stirred evenly before use.
If the problem is still not resolved after self-inspection, Guoli Chemical will provide customers with comprehensive after-sales technical support services. You can organize the batch number of the problematic product, a detailed description of the phenomenon (such as appearance changes, performance degradation, process abnormalities, etc.), and relevant operating condition records, and contact our technical engineers through official channels. We usually provide preliminary diagnosis and solution suggestions within 1-2 working days.
In case of emergency (leakage, contact, fire, etc.), please handle immediately according to the following points:
| Situation | Treatment measures |
|---|---|
| Skin contact | Immediately rinse with plenty of water and soap. This product is non-irritating to the skin, but still needs to be thoroughly cleaned. |
| Eye contact | Rinse continuously for at least 15 minutes, lifting eyelids. If irritation persists (may cause mild transient discomfort), seek medical attention promptly. |
| Leakage treatment | Absorb with inert materials such as sand, place in a closed container and dispose of as hazardous waste, prevent from entering sewers. |
| Fire | Use water mist, foam, dry powder, or CO₂ to extinguish. Flash point is approximately 220–230°C. Combustion may produce CO and irritating smoke. |
