Polyester polyols are a key component in the formulation of rigid polyurethane (PU) foam. Compared to polyether polyols, polyester polyols exhibit higher functionality, increased hardness, and better resistance to abrasion, chemicals, and thermal aging. In rigid foam applications, polyester polyols are valued for their low thermal conductivity, mechanical strength, and compatibility with blowing agents and isocyanates.
Rigid PU foam made with polyester polyols is widely used in insulation panels, cold storage units, building facades, pipelines, and automotive components. The unique molecular structure of polyester polyols contributes to dense, closed-cell foam that offers excellent insulation properties and load-bearing performance.
Our polyester polyols for rigid foam are manufactured with strict quality control, ensuring consistency and optimal performance in demanding environments. The typical specifications include:
Hydroxyl Value: 315 ± 15 mgKOH/g
Acid Value: ≤ 2.0 mgKOH/g
Moisture Content: ≤ 0.1%
Viscosity (25°C): 3000 ± 500 mPa·s
Appearance: Pale yellow transparent viscous liquid
These parameters make our polyols suitable for fast-curing systems, high compressive strength requirements, and consistent foaming behavior.
Polyester polyols are extensively used in the production of PIR (polyisocyanurate) and PUR panels for insulation in walls, roofs, and flooring systems. The excellent thermal resistance ensures minimal energy loss, making buildings more energy efficient.
In the cold storage and refrigeration industry, rigid foam formulated with polyester polyols is used in refrigeration doors, cold room panels, and refrigerated trucks. It offers dimensional stability and thermal insulation even in sub-zero temperatures.
Used in refrigerators, freezers, water heaters, and industrial cooling equipment, polyester polyols help form rigid foams that maintain internal temperature while reducing power consumption.
In petrochemical and district heating systems, rigid foam with polyester polyol serves as an effective thermal insulator for underground or exposed pipelines, maintaining operational efficiency in extreme climates.
Polyester polyols are used in the formulation of structural foam for vehicle interiors, doors, and ceiling panels, offering lightweight durability and noise reduction.
Our polyester polyols offer high hydroxyl values, enabling better crosslinking with isocyanates, resulting in a stronger and more rigid foam structure.
Foams formulated with our polyols demonstrate low thermal conductivity, helping meet high energy-efficiency standards across industries.
Rigid foam exhibits high compressive strength, load-bearing capacity, and dimensional stability, even under long-term use and thermal cycling.
Produced with low acid values and minimal VOCs, our polyols support sustainable manufacturing practices and safer end products.
Our polyester polyols can be blended with other polyol types or flame-retardant additives to tailor foam properties for specific applications.
We offer more than just high-quality raw materials. With years of expertise in polyurethane chemistry and a customer-centric approach, we provide:
Technical support & formulation guidance
Customizable hydroxyl/acid values
Reliable and stable supply chain
Competitive pricing & fast delivery
Standard Packaging: 200 kg drums / 1000 kg IBC totes
Storage Conditions: Keep in tightly closed containers in a dry, ventilated place. Avoid exposure to direct sunlight or freezing conditions.
Shelf Life: 12 months under recommended storage conditions.
