In flexible polyurethane foam systems, control over the cell structure is a key factor in the final performance of the product\u2014whether in terms of comfort, mechanical properties, or thermal behavior. In this context, silicone surfactants <\/strong>play a vital role in the formation and stabilization of foam during the foaming reaction.<\/p>\n\n\n\n

AMISIL AMS 480<\/strong> is a silicone specifically designed for high-density formulations that require an open-cell structure,<\/strong> with a focus on morphological control and minimal interference in cell closure. It is a technical solution tailored for applications that require air-permeable foams with structural uniformity and excellent physical performance.<\/p>\n\n\n\n

Technical Profile of AMISIL AMS 480<\/h2>\n\n\n\n

AMISIL AMS 480 belongs to the category of low-surfactancy silicones<\/strong>, which means it has a lower emulsification capacity in the reactive system and a reduced tendency to promote the closure of the formed cells. In other words, it acts as a non-aggressive<\/strong> cell structuring agent, ideal for systems aiming for open, fine, and homogeneous cells.<\/strong><\/p>\n\n\n\n

Key Technical Properties<\/strong>:<\/p>\n\n\n\n

    \n
  • Low surfactancy<\/strong> \u2192 reduces cell closure;<\/li>\n\n\n\n
  • Good morphological uniformity<\/strong> \u2192 promotes small and consistent cells;<\/li>\n\n\n\n
  • Compatibility with high-density formulations<\/strong> \u2192 suitable for foams between 25\u201355 kg\/m\u00b3;<\/li>\n\n\n\n
  • Assists in controlled foam expansion<\/strong> \u2192 contributing to elasticity and post-compression recovery.<\/li>\n<\/ul>\n\n\n\n

    Typical Applications<\/h2>\n\n\n\n

    AMISIL AMS 480 is recommended for formulations in which:<\/p>\n\n\n\n

      \n
    • The cell structure needs to be open to allow airflow or gas permeability;<\/li>\n\n\n\n
    • Performance is required in foams demanding high resilience without compromising ventilation;<\/li>\n\n\n\n
    • The project requires high density with controlled cell distribution, minimizing internal mechanical gradients.<\/li>\n\n\n\n
    • Possible applications<\/strong>: insoles, bra cups, technical parts, among others.<\/li>\n<\/ul>\n\n\n\n
      \n\n\n\n

      Safety and Sustainability<\/h2>\n\n\n\n

      From a regulatory standpoint, AMISIL AMS 480 does not present any concerning toxicological profile <\/strong>and is not classified as carcinogenic, mutagenic, or reproductive toxicant. While it is derived from fossil sources, it complies with modern occupational safety and environmental requirements, with low impact throughout the PU foam life cycle.<\/strong><\/p>\n\n\n\n

      \n\n\n\n

      AMISIL AMS 480<\/strong> is the ideal technical choice for foam systems requiring open structure, high density, and precise cell morphology control, without compromising reaction stability or foam integrity. It is an essential tool for foam producers and formulation chemists seeking performance and consistency in the process.<\/p>\n\n\n\n
