Summary of Core Advantages

  1. Broad Temperature Adaptability
    FACTOP’s operating temperature range (-60~200°C) is on par with Domestic Medium Hardness Silicone Foam and superior to 3M F7351 (-40~200°C), Dow Corning 3-6548 (-40~180°C), and Wacker Elastosil SC 870 A/B (-50~180°C). It is suitable for more extreme high- and low-temperature scenarios (e.g., polar regions, high-temperature equipment compartments).
  2. Superior Mechanical Properties
  • Compressive strength (≥1.2 MPa) is significantly higher than competitors (Wacker SC 870 A/B: 0.06 MPa; Pres-On S800: 0.062 MPa; Domestic Medium Hardness: 0.6 MPa), enabling structural stability under high-pressure environments.
  • Tensile strength (0.3~0.8 MPa) is comparable to Domestic Medium Hardness and superior to Dow Corning 3-6548 (0.23 MPa), making it suitable for dynamic sealing scenarios requiring high toughness.
  1. Outstanding Environmental Aging Resistance
  • Indicators such as moist heat resistance (≥360h) and freeze-thaw cycle resistance (≥15 cycles) are industry-leading, far exceeding the publicly available data of brands like 3M, Dow Corning, and Wacker. It is suitable for areas with high humidity (e.g., coastal regions) or severe temperature differences (e.g., cold zones).
  • Water absorption (<0.2%) is much lower than Pres-On S800 (1.4%) and Domestic Medium Hardness (≤1.5%), allowing long-term low water absorption in humid environments and avoiding performance degradation.
  1. Environmental Protection & Safety Performance
    FACTOP meets RoHS 10 items certification, with stricter environmental requirements than the industry’s general RoHS/REACH standards; its limiting oxygen index (≥30) also outperforms competitors that do not disclose this indicator, resulting in less smoke release during fire and higher safety.
  2. Construction & Application Flexibility
    As a two-component liquid foaming agent, FACTOP can be mixed on-site and then foamed into shape, adapting to complex three-dimensional sealing requirements (e.g., cable bundles, pipe penetrations). In contrast, Pres-On S800 (as preformed tape) has limited adaptability.

Conclusion

FACTOP polymer silicone foaming agent comprehensively surpasses international brands (3M, Dow Corning, Wacker, etc.) and domestic similar products in core indicators such as temperature adaptability, mechanical strength, environmental aging resistance, and environmental safety. It is especially suitable for harsh scenarios with extreme temperatures, high pressure, and high humidity (e.g., new energy battery compartments, industrial equipment sealing, firestop in high-rise buildings). Its technical parameters not only address the shortcomings of competitors but also set industry benchmarks in multiple indicators, making it the first choice for high-reliability sealing and fire protection solutions.
