Sorbitol-initiatied Polyether Polyols for Rigid Foams

Sorbitol-initiated polyether polyols, a polyether polyols synthesized from Sorbitol as the starting material, is a special chemical designed for the production of rigid polyurethane foam. This kind of polyether polyol is obtained by ring-opening polymerization of propylene oxide (PO) or other epoxy-based monomers using the polyhydroxyl structure of sorbitol as the starting point of the reaction, and has unique advantages and application characteristics.

Due to its excellent properties, Sorbitol-initiated polyether polyols for rigid foams play a key role in several industries, especially in areas requiring high strength, thermal insulation and energy saving.

1.Building insulation materials: used for insulation of walls, roofs and floors to improve the energy efficiency of buildings.
Refrigeration equipment: as the insulation material of refrigerators, freezers, refrigerated trucks, etc., to maintain a low temperature environment and reduce energy consumption.
2.Pipe insulation: applied to industrial pipes and domestic hot water pipe insulation to prevent heat loss.
3.Home appliance manufacturing: Used for refrigerators, water heaters and other home appliance insulation layer, to provide efficient insulation effect.
4.Automotive parts: Make automotive interior parts, such as door panels, instrument panels, etc., to reduce weight and provide sound insulation and heat insulation.
5.Packaging materials: Certain rigid foams can be used as protective packaging for high-grade fragile products or refrigerated foods.
6.Mold and model making: Used in some mold making that requires accurate shape and dimensional stability.

200Kg or 220Kg metal drum packing,ISO package and ISO-TANK are also can be provided.

Store in cool, dry and ventilated place, period of validity is one year.

Q: What are the advantages of sorbitol-derived polyether polyols over conventional polyether polyols?

A: Sorbitol-derived polyether polyols typically have a higher hydroxyl number and a more complex molecular structure, which allows them to provide better mechanical properties, such as higher strength and rigidity, when preparing hard foams. In addition, they have the potential to improve the heat resistance and dimensional stability of the foam, while they are also more environmentally friendly due to the renewability of sorbitol.

Q: What is the environmental impact of these polyether polyols? Is it sustainable?

A: Sorbitol is a naturally derived polyol derived from plants such as corn and wheat, so the use of sorbitol-derived polyether polyols can help reduce the dependence on petroleum-based feedstocks and reduce the carbon footprint. The choice of this bio-based material supports sustainable development and is also more environmentally friendly in the disposal of the final product.

Q: How do they perform in rigid foam applications?

A: Sorbitol-derived polyether polyols can provide excellent closed-cell structure in hard foam applications, which means better insulation and water resistance. They also improve the compressive strength of foams, making them excellent in areas such as building insulation, refrigeration equipment and packaging materials.
