Key Properties of Polyether Polyol PPG3000 for Rigid Foam Insulation
For industries reliant on effective thermal insulation, understanding the core components of rigid polyurethane (PU) foam is crucial. Polyether polyols, specifically grades like PPG3000, play a pivotal role in achieving the desired insulation performance, structural integrity, and processing efficiency. As a dedicated supplier of high-quality chemical raw materials, we highlight the essential properties of Polyether Polyol PPG3000 that make it a preferred choice for manufacturers.
Polyether Polyol PPG3000 is distinguished by its specific average molecular weight, typically around 3000. This molecular weight significantly influences the viscosity and reactivity of the polyol, which in turn dictates the flowability and processing characteristics during foam production. A well-controlled molecular weight ensures consistent cell structure and mechanical properties in the final rigid foam product, making it easier for formulators to achieve precise outcomes. For procurement managers, verifying this specification is key to ensuring batch-to-batch consistency and predictable product performance.
Viscosity is another critical parameter for PPG3000. With a viscosity ranging from 460-530 cps at 25ºC, this polyether polyol offers excellent handling and mixing capabilities. Lower viscosity facilitates easier pumping, blending with isocyanates, and effective penetration into molds or spray applications, leading to a more homogeneous foam with reduced void defects. This property is vital for efficient production lines, reducing processing time and potential material waste. When you buy Polyether Polyol PPG3000 from us, you are assured of these optimized viscosity characteristics.
The hydroxy number, typically between 54-58 mgKOH/g for PPG3000, is a measure of the hydroxyl group concentration, which directly correlates to the polyol's reactivity with isocyanates. A suitable hydroxy number is essential for achieving the correct cross-linking density, which in turn determines the foam's mechanical strength, hardness, and thermal insulation properties. Furthermore, a low water content (0.06% max) and acid number (0.03 max) are indicative of the polyol's purity and stability, preventing unwanted side reactions and ensuring the longevity and performance of the finished polyurethane product.
These carefully controlled properties make Polyether Polyol PPG3000 an exceptional raw material for various rigid foam applications, including building insulation panels, spray foam insulation, refrigerated transport, and pipe insulation. Its ability to impart good mechanical properties and foam stability, alongside excellent flowability, allows for the creation of lightweight yet strong materials with superior thermal resistance.
