Polyester Polyol For All Water foaming is a water-reactive polyol designed for water-blown polyurethane foam systems, eliminating the need for hydrocarbon or fluorinated blowing agents. This polyol leverages the isocyanate-water reaction to generate CO₂ gas, enabling low-VOC, halogen-free foam production. Its molecular structure balances hydrophilic segments (for water compatibility) and hydrophobic chains (for foam stability), with a hydroxyl number of 200–350 mg KOH/g and functionality of 2.8–3.2. With a viscosity of 4,000–8,000 cps at 25°C, it supports diverse processing methods including spray, pour, and molding.
Water Compatibility
The controlled hydrophilic-lipophilic balance (HLB) ensures uniform mixing with water (up to 10% by weight), preventing phase separation and enabling stable foam rise with cell size distribution ≤50 μm.
Efficient CO₂ Generation
Optimizes the isocyanate-water reaction to produce consistent CO₂ output, achieving foam density 25–40 kg/m³ with closed-cell content ≥85% in rigid formulations. This reduces material usage while maintaining insulation performance.
Environmental Advantages
Enables zero ozone depletion potential (ODP) and low GWP (≤1) foam systems, complying with EU Ecolabel and LEED requirements. Foams emit ≤5 ppm VOCs and contain no formaldehyde or halogens.
Processing Versatility
Adaptable to rigid and semi-rigid applications, with adjustable cure times (10–30 minutes) to suit production needs. Compatible with standard PU additives like surfactants and flame retardants without performance loss.
Building Insulation
Spray Foam: Used in open-cell and closed-cell spray insulation for walls and attics, providing air sealing and thermal resistance (λ-value ≤0.024 W/m·K).
Insulation Boards: Manufactures rigid foam boards for retrofitting existing buildings, with compressive strength ≥0.8 MPa and moisture resistance (water absorption ≤1.0%).
Packaging and Cushioning
Molded Foam Inserts: Creates custom-fit packaging for electronics and medical devices, with shock absorption ≥80% at 1m drop height.
Loose-Fill Packaging: Produces lightweight, biodegradable loose-fill as an alternative to polystyrene peanuts.
Automotive and Industrial
Interior Trim: Forms semi-rigid foam for door panels and headliners, with low odor and VOC emissions ≤3 ppm to meet automotive standards.
Sound Insulation: Used in acoustic foam barriers for machinery enclosures, reducing noise transmission by 20–30% (measured at 1kHz).
Container: Store in airtight HDPE or stainless steel containers to prevent moisture absorption (water content ≤0.2%).
Conditions: Maintain temperatures at 5–30°C with humidity ≤60%, away from direct sunlight.
Handling: Avoid contact with strong acids and isocyanates when not in production, as premature reaction may occur.
