Chemical Name: PPG 1000 Polyether Polyol
PPG 1000 polyether polyol is a 1,000-molecular-weight polypropylene glycol. The terminal end-groups are predominantly secondary hydroxyls and have a relatively low reactivity. It is compatible with most polyether polyols and can be blended with other diols or triols to achieve desirable modifications of product properties. This polyol is acidified with a low level of phosphoric acid, making it suitable for use in isocyanate-terminated prepolymers

Inhalation:
Remove victim from exposure to fresh air immediately, if not breathing, give artifical respiration; if breathing is difficult, give medical oxygen. Get medical aid immediately. Ingestion: Rinse mouth with plenty of milk or water (only if victim is conscious and alert). Get medical aid immediately
Skin Contact:
If skin contact occurs, wash the effected area with plenty of water and a neutral soap for a minimum of 5 minutes
Eye Contact:
If eye contact occurs, wash with plenty of clean water or amphoteric eye solution for a minimum of 15 minutes, holding the eyes open, medical advice should be followed
PPG 1000 polyol is slightly hygroscopic and may absorb water. Containers should be kept tightly closed and protected from contamination with moisture and foreign materials, which can adversely affect product quality. This polyol can become quite viscous at low tem-peratures. For ease of handling, storage temperatures between 20°C (68°F) and 60°C (140°F) are recommended
PPG 1000 is dispatched in polyethylene or corrugated steel, galvanized or carbon steel drums
Shelf life: PPG 1000 is stable for 2 years when stored in the original sealed containers in a cool and dry place
Appropriate literature has been assembled which provides information concerning the health and safety precautions that must be observed when handling PPG 1000 polyol. Before working with these products, you must read and become familiar with the available information on their hazards, proper use, and handling
PPG 1000 polyol is used in a broad range of urethane foam and other applications including coatings, solvent and water-based adhesives, caulks, sealants, elastomers, defoamers, humectants, potting compounds, tire fill, inks, lubricants, antistatic agents, crude oil de-emulsifiers and plasticizers. As with any product, use of PPG 1000 polyol in a given application must be tested (including but not limited to field testing) in advance by the user to determine suitability
