ASC CS220 CALCIUM SILICATE INSULATION


  It is the microcellular structured inorganic rigid and super-light heat insulation material mainly composed of inorganic siliceous and calcium and made by special technology such as the hydrothermal reaction under high temperature and high pressure etc. And it's the national inspection-free product that has firstly won the ISO9001 certification in the same industry. It can still maintain the high insulating effect at 650℃ and is advantageous in the stability of coping with temperature changes. With super-low chloride ion content, it can provide very nice protection on pipelines, and is prefabricated to shape up, greatly extending the service life. Additionally, the company has kept upgrading product technology to improve product, reducing the product density from 220kg/m³ to 180kg/m³ while maintaining its strength, thus reducing the thermal conductivity from 0.065 to 0.049.

· Advantages

  • A1

    Asbestos Free

    Made from algous fossil from hundreds of millions of years ago, the product is entirely asbestos-free and non-poisonous to human body.

  • A2 

    Superior Strength

    With similar density, the strength of this material is the highest among all the inorganic rigid insulation materials with better compressive performance and is not easy to bend, Compared with ASC CS170, ASC CS220 product has better physical strength.

  • A3

    Good Anti-corrosion

    The super low chloride ion content and alkalescence have good protection for metal pipes, which greatly prolongs the service life of pipes and equipment and greatly reduces maintenance cost, bringing lasting protection and better durability。

  • A4

    Wonderful Non-combustibility

    The product passed the EC certificate test by Germanischer Lloyd and has been identified as non-combustible material。 It also passed the test by National Center for Quality Supervision and Testing of Fire Building Materials which identifies it as Grade A1 incombustible material。

  • A5

    Good Stability

    Long time soaking in water will not lead to pulverization. Various performance remains stable after drying.

  • A6

    Excellent Soundproofing Performance

    Great soundproofing effectively reduces industrial noises.


· Applicable Scope

 It's applicable to equipment and pipeline facilities in petroleum refinery, chemical industry, hydroelectricity, nuclear power, thermal power and city heat supply network.
