The performance of a flexible polyurethane foam is directly linked to its cellular morphology, whose key parameters — cell size, uniformity, and stability — determine critical properties such as comfort, compressibility, resilience, and durability. To ensure proper control over these aspects, silicone surfactants are essential, especially in low-density systems.
AMISIL AMS 452 is a high-surfactancy silicone designed to promote efficient cell formation and structural stabilization in low to medium-density foams, meeting the high standards of the furniture, automotive, and bedding industries.
Technical Features
Formulated with high-activity base silanes, AMISIL 452 provides elevated surfactancy and excellent foam stabilization capacity, supporting both nucleation and cell preservation during the expansion and curing stages.
Key technical attributes:
- High surfactancy → promotes the formation of a large number of fine cells
- High stabilization → maintains block integrity even in ultra-low-density foams
- Recommended for foam densities ranging from 12 to 30 kg/m³
- Compatible with TDI, MDI, and blended systems
- Suitable for discontinuous block and cylindrical block processes
Operational Advantages
Using AMISIL 452 enables:
- Production of low-density foams with good block stability
- Reduction of morphological defects, such as broken or collapsed cell regions
- Improved batch-to-batch reproducibility
- Optimization of blowing agent consumption, with better control of final density
This combination of benefits makes AMISIL AMS 452 a versatile and competitive silicone for a wide range of PU foam types.
Recommended Applications
AMISIL AMS 452 is ideal for:
- Mattress manufacturing
- Furniture and upholstery industry
- Automotive technical parts
- Foams for lamination and combustion-barrier layers
For foam systems where high surfactancy and cell stability are essential, AMISIL AMS 452 offers the ideal technical balance. Its application enables the development of lightweight, resilient foams with predictable performance at an industrial scale.
