Flexible Foam Polyether Polyol PPG, Raw Material For Sofa, Mattress And Car‑seat PU Foam

Polyether polyols are polyol polymers synthesized by catalytic addition polymerization of initiators containing active hydrogen with cyclic oxides such as propylene oxide (PO) and ethylene oxide (EO). Polypropylene glycol (PPG / polyoxypropylene, CAS: 9003-11-6) is the mainstream product of this series.

It is a colorless to brownish-yellow viscous liquid at ambient temperature, hygroscopic, slightly soluble in water and readily soluble in organic solvents including aromatic hydrocarbons, alcohols and ketones. Specific gravity: 1.03–1.1, boiling point >200℃, flash point >230℃. Hydroxyl value and viscosity are key performance indicators. Grades for flexible foam, rigid foam, elastomers and adhesives can be produced by formula adjustment: low-hydroxyl-value and low-viscosity grades are mainly used for flexible polyurethane foam; high-hydroxyl-value grades are suitable for rigid thermal insulation foam. Some modified polyethers feature low viscosity, low toxicity and hydrophobicity to improve the water resistance and long-term durability of finished products.

As a core raw material for polyurethane (PU), it is widely applied in furniture foam, automotive interiors, home appliances, building thermal insulation, elastomers and adhesives. Special grades can be used as defoamers and non-ionic surfactants.

Packed in clean, dry and sealed galvanized steel drums. Carbon steel, aluminum, PE or PP containers are acceptable for storage. Storage temperature ≤70℃. Nitrogen blanketing is recommended to prevent moisture absorption and oxidation. Store away from sunlight, rain and ignition sources. This product is not readily biodegradable; prevent leakage into surface water or groundwater.

Conventional grades have low toxicity with generally no obvious skin irritation. Amine-modified polyethers are alkaline and may irritate the eyes and skin.

• Avoid prolonged exposure to air and open flame. Fabrics and thermal insulation materials soaked with polyether may risk spontaneous combustion.
• Skin contact: rinse thoroughly with plenty of water.
• Eye contact: flush eyes continuously with water for at least 15 minutes and seek medical attention.
• Spill: absorb with sand, absorbent cloth or similar materials, then flush the area with large amounts of water.
• Fire-fighting media: foam, dry powder, CO₂, water spray.
