    • Product Number:EPA001
  • Details
  • Ingredients of Epaflex【rubber + plastic】
    “Epaflex” High Density Cell Rubber and Plastic Fireproof Insulation Material is produced by foaming quality synthetic elastic mass with sophisticated scientific process, having a structure of highly airtight cells. It has been proven that, with its extremely low coefficient of heat conductivity, Epaflex can sufficiently meet the insulation effect in different work conditions and environments. It is an ideal heat-insulating material.
    Product structure of Epaflex
    1、The advantage of this material over other rubber and plastic materials is that it has a high-density airtight cell structure, with discontinuous cells (and the walls of the independent cells are strong and hard to break), which means, the internal cells of the product do not overlap each other. Hence, the product has a low coefficient of heat conductivity (λ=0.033).
    2、Good flexibility, superb elasticity.
    3、The product surface is compounded with fireproof aluminum foil, smooth and even, giving a luxury and beautiful appearance.
    Pioneering and superior performance advantage of Epaflex rubber and plastic insulating material
    1、Pioneering and superior heat-insulating performance
    According to the test (by Dujiangyan Quality Testing Center), this product has a very low coefficient of heat conductivity (λ=0.033w/m·k at an average temperature of 0oC).
    2、Excellent fireproof performance: (heat-insulating + non-flammable)
    Epaflex is added with fire-retardant, and its fireproof performance meets national GB8624 hard-to-burn Class B1 standard. When it is burned on a flame, it will not drop fireballs. Moreover, the material surface is compounded with fireproof aluminum foil. Hence, the product is not only hard-to-burn, but also non-flammable.
    3、Moisture resisting factor: μ→+∞
    The moisture resisting factor of the material itself is μ≥4500. Thanks to the adoption of compounded fireproof and moisture-proof aluminum foil technology on the surface of the material, its capability to resist moisture penetration increases almost from μ=4500 to μ→+∞(infinite extremity).
    4、Epaflex does not contain PVC
    When charred by fire, the smoke it generates does not contain the toxic element of Chlorine, and hence is absolutely safe.
    5、Stable and reliable safety combustion performance
    Epaflex material has been tested by (Dujiangyan) National Quality Testing Center, with the result that its oxygen index is ≥32%, meeting national fire-proof building material inflammable Class B1 standard.
    6、Hygroscopic coefficient: →0%
    Epaflex does not absorb water even when it is soaked in water for a long time (the material itself is of high-density air-tight cell structure.). Covered by high-strength, i.e. fireproof and moisture-proof aluminum foil, the hygroscopic coefficient of the surface of the heat-insulating layer is almost 0%.
    7、Good frost-resisting property
    The mechanical strength of Epaflex material will not decrease even if the material is frozen with water. After cycles of freezing and thawing, the material still maintains its major physical property.
    8、Superb mechanical strength of airtight cells
    Epaflex is featured with high-density airtight cell structure with tiny and evenly arranged cells. With its superior vacuum hygroscopic coefficient and good mechanical strength of the airtight cells, it is very hard to break even under external forces (when squeezed, it will not have a noise of breaking.), hence is very convenient for engineering.
    9、Superior aging resistance
    After 150 hours of aging resistance (UV) test, there are still no cracks, no pinholes, and no deformation happened to the material. Moreover, the surface of the material is compounded with aluminum protection layer, giving more outstanding aging resistance. Its duration can last up to 15 years.
