High-Purity Solvents, Polyurethane (PU) and Resin

Polymer Polyol

Polymer Polyols (often abbreviated as POP), specifically those utilizing CAS 9082-00-2 as a base, are high-performance dispersions essential to the polyurethane (PU) industry. CAS 9082-00-2 identifies the base polyether triol—specifically a glycerol-initiated polymer of ethylene oxide and propylene oxide. In the context of “Polymer Polyols,” this base liquid acts as a continuous phase for finely dispersed solid polymer particles, typically a copolymer of Styrene and Acrylonitrile (SAN).

These materials are engineered to overcome the mechanical limitations of standard polyether polyols. By incorporating solid filler particles at the molecular level, polymer polyols significantly increase the load-bearing capacity (hardness) of flexible foams without requiring an increase in foam density. This technical synergy allows manufacturers to produce high-resilience (HR) and combustion-modified high-resilience (CMHR) foams that offer a sophisticated balance of comfort, durability, and structural integrity. They are foundational in modern chemical engineering for optimizing material costs while enhancing the physical properties of cellular plastics.

Attributes

Key Features and Benefits

Superior Load-Bearing (IFD): Significantly enhances Indentation Force Deflection (IFD), allowing for the production of much firmer foams than standard polyols.
Density Optimization: Enables the formulation of high-hardness foams at lower densities, leading to significant chemical cost savings.
Excellent Cell Opening: Acts as a cell-regulating agent, promoting an open-cell structure which prevents foam shrinkage and improves breathability.
Dispersion Stability: Advanced grafting technology ensures the SAN solids remain in suspension, preventing sedimentation during long-term storage or high-pressure processing.
Enhanced Durability: Improves the fatigue resistance and tensile strength of the foam, extending the service life of end products.
Low VOC Profile: Modern grades are stripped of residual monomers, meeting stringent automotive and indoor air quality emissions standards.

Specifications

Technical Highlights

Chemical Matrix: Glycerol-initiated polyoxypropylene-polyoxyethylene triol (CAS 9082-00-2) providing a trifunctional backbone.
Solids Content: Typically ranges from 10% to 50% by weight, allowing for precise control over the final foam hardness.
Hydroxyl (OH) Value: Generally maintained in the range of 20 to 35 mg KOH/g for high-solids variants to ensure controlled reactivity with isocyanates.
Controlled Viscosity: Formulated to maintain manageable viscosity (typically 1,500–6,000 mPa·s at 25°C) for ease of pumping and mixing.
Particle Size Morphology: Solid polymer particles are engineered to be consistently under 2 microns, ensuring compatibility with high-pressure impingement mixing heads.
Primary Hydroxyl Content: Often tailored with high primary OH groups for high-resilience “cold-cure” molding applications.
