CAS 9082-00-2 Polyether Polyol For Polyurethane Elastomer Coating And Adhesives POP

Polyether Polyol For Polyurethane Elastomer, Coating And Adhesives POP CAS 9082-00-2

Description:

• Polyether polyol is a polymer composed of repeating ethylene oxide (EO) and/or propylene oxide (PO) units. These units form a chain-like structure with hydroxyl (OH) end groups. The molecular weight and composition of polyether polyols can vary depending on the specific application and desired properties.

Specification:

• Molecular Weight: Polyether polyols are available in a wide range of molecular weights, typically ranging from a few hundred to several thousand grams per mole.
• Hydroxyl Number: The hydroxyl number indicates the concentration of hydroxyl groups in the polyol and is given in milligrams of potassium hydroxide (KOH) required to neutralize the hydroxyl groups in one gram of the polyol.
• Functionality: Polyether polyols can have different functionalities, indicating the number of reactive hydroxyl groups per molecule. Common functionalities include diols (two hydroxyl groups), triols (three hydroxyl groups), and higher functionalities.

Application:

1. Polyurethane Foams: Polyether polyols are a key component in the production of flexible and rigid polyurethane foams. The polyols react with isocyanates to form a three-dimensional network, resulting in foams with varying properties such as softness, resilience, and insulation capabilities. Flexible foams find applications in furniture, bedding, automotive seating, and insulation, while rigid foams are used for insulation, construction, and packaging.

2. Coatings and Adhesives: Polyether polyols are used in the formulation of coatings and adhesives to provide flexibility, durability, and adhesion properties. They serve as a backbone in the polymer matrix, contributing to the final film's mechanical properties, chemical resistance, and film-forming characteristics.

3. Elastomers: Polyether polyols are utilized in the production of elastomers, including thermoplastic polyurethane (TPU) and cast polyurethane elastomers. These materials exhibit excellent elasticity, abrasion resistance, and flexibility, making them suitable for applications such as seals, gaskets, belts, footwear, and automotive parts.

Features:

• Hydrophilic Nature: Polyether polyols possess a hydrophilic nature due to the presence of linkages. This property can enhance their compatibility with water or hydrophilic additives in certain applications.

• Customization: The composition, molecular weight, and functionality of polyether polyols can be tailored to meet specific requirements, allowing for customization of the final polyurethane product's properties.

• Good Compatibility: Polyether polyols exhibit good compatibility with a wide range of additives, fillers, and other components commonly used in polyurethane formulations, enabling the formulation of diverse products with desired characteristics.

• Wide Range of Hardness: Polyether polyols can be used to produce polyurethane foams and elastomers with a broad range of hardness, from very soft and flexible to rigid and tough.

• Excellent Resilience and Elasticity: Polyurethane products based on polyether polyols generally exhibit excellent resilience, elasticity, and resistance to deformation, making them suitable for applications requiring cushioning, shock absorption, and flexibility.
