PETOL 28-3B is a tri-functional highly reactive polyether polyol, with a 6000 nominal molecular weight designed for obtaining high resilience flexible polyurethane foams. Due to the high content of EO, the product may become opalescent at temperatures below 30°C. PETOL 28-3B results from the addition of propylene oxide and ethylene oxide to glycerin, under base catalysis.

Safety & Health

Safety Consideration

Handling and using, this product must be in accordance with the practice of industrial products and preventing environmental contamination.

Packaging & Availability

Packaging Information

The product is delivered in stainless steel or coated rail or car tanks, property of supplier or client.

Storage & Handling

Storage Information

Due to its hygroscopic nature, the product is stored in tightly closed containers under nitrogen blanket, in cold, dry, vented areas, far from heat, moisture and inconsistent materials, at temperatures between +20°C and +50 °C. At temperatures lower than 20°C, handling difficulties arise due to increase of polyol viscosity.
