Silicone Surfactant AC-3525 Polyester PU Foam Stabilizer NPEO-Free
NPEO-Free Universal Foam Stabilizer
AC-3525 is a nonylphenol ethoxylate (NPEO)-free universal foam stabilizer specially developed for the production of polyester-based polyurethane foam. It combines superior emulsification power with excellent cell opening efficiency, making it the ideal choice for high-performance PU foam formulations.
Key Features & Advantages
- Outstanding Emulsification Performance: Forms clear and homogeneous activator solutions with commonly used polyester foam catalysts without requiring additional emulsifiers.
- Superior Cell Opening Efficiency: Delivers excellent foam stabilization and cell structure control for improved foam breathability and recovery performance.
- Broad Foaming Compatibility: Versatile and suitable for various polyester-based polyurethane foam formulations, including semi-rigid foam with high T65 ratio.
- NPEO-Free & Environmentally Compliant: Fully free of nonylphenol ethoxylate, meeting global environmental and safety regulations including REACH SVHC requirements.
- Extremely Low VOC: Ultra-low volatile organic content makes it perfect for foam products subject to fogging tests, ensuring compliance with automotive interior standards.
- Flame-Retardant Foam Compatible: Facilitates the production of flame-retardant foam and helps products pass combustion tests more easily.
- Improved Die-Cutability: Can be safely used with paraffin oil additives to effectively improve foam die-cutability in downstream processing.
- Cost-Efficient Dosage: Typical recommended dosage of only 0.8–1.5 pphp ensures economical formulation costs.

Frequently Asked Questions
Is AC-3525 compatible with TDI and MDI based polyurethane systems?
Yes, AC-3525 is a universal foam stabilizer designed for polyester-based polyurethane foam. It demonstrates excellent compatibility with both TDI and MDI systems, forming clear and homogeneous activator solutions with commonly used catalysts including N-methylmorpholine and N,N-dimethylbenzylamine.
What is the recommended dosage for flame-retardant foam formulations?
For flame-retardant foam formulations, the recommended dosage range is 1.0–1.5 pphp. AC-3525 facilitates the incorporation of flame retardants and helps finished foam products pass combustion tests more easily. Our technical team can provide formulation-specific guidance upon request.
Does AC-3525 meet automotive interior VOC and fogging requirements?
Absolutely. AC-3525 features extremely low volatile organic content (VOC), making it specifically suitable for foam products that must pass stringent fogging tests, including automotive interior applications such as seat cushions, headrests, and armrests. It is NPEO-free and compliant with REACH SVHC regulations.
Can I request a free sample for lab-scale foaming trials?
Yes, we offer free samples up to 1 KG for qualified customers to conduct lab-scale foaming evaluations. Standard lead time for samples is 3-5 working days. Please contact our technical support team with your specific formulation details for a faster turnaround.
