Product introduction
Polyether polyols are high molecular weight compounds featuring ether bonds (—R—O—R—) in their main chain and multiple hydroxyl groups (—OH) on terminal or side groups. They are synthesized through the ring-opening polymerization of olefin oxides—primarily propylene oxide, with ethylene oxide also used—initiated by low molecular weight polyols, polyamines, or active hydrogen-containing compounds in the presence of catalysts. Appearance: colorless, light yellow, or brown liquid.

Product application
Polyurethane Foam:
Polyether polyols are key to producing soft and rigid polyurethane foams, widely applied in furniture, car seats, and building insulation. These foams offer superior thermal insulation, shock absorption, durability, and a lightweight structure.
Polyurethane Elastomers:
Polyether polyols form polyurethane elastomers with excellent mechanical strength and wear resistance, ideal for tires, sports footwear, seals, and automotive parts, meeting demands for high performance and durability.
Polyurethane Coatings:
In coatings, polyether polyols deliver strong adhesion, weather resistance, and chemical stability, making them perfect for industrial and architectural uses. These coatings enhance aesthetics while protecting surfaces from environmental damage.
Polyurethane Adhesives:
Polyether polyols enhance polyurethane adhesives with robust bonding strength and water resistance, suitable for joining wood, metal, and plastic in industrial and construction settings, ensuring reliable, long-lasting connections.
Product advantages
Excellent Flexibility:
Polyether polyols provide superior elasticity and flexibility, allowing end products like foams, coatings, and adhesives to exhibit exceptional deformation capabilities.
Low-Temperature Performance:
Polyether polyols retain excellent physical properties in cold environments, making them ideal for applications in low-temperature regions.
Water Resistance:
With strong water and moisture resistance, polyether polyols ensure polyurethane products maintain stable performance in humid conditions.
Chemical Stability:
Offering robust resistance to chemical corrosion, polyether polyols are well-suited for packaging and storing various chemicals.
Packaging & Storage
Packaging:
Polyether polyols are packed in IBC containers and iron drums.
Storage Conditions:
Store between 2°C and 35°C in a dry, ventilated location, protected from direct sunlight and rain. Shelf life is 12 months; post-expiration use requires passing a quality test.
