ASC microcellular calcium silicate heat insulation board is a kind of new-type board dominated by siliceous and calcareous materials and made by such working procedures as pulping, shaping, steam curing, drying and post processing etc. It is prefabricated to shape up with good trampling resistance and has the same service life with buildings; it is resistant to fire, water and moisture, and also resistant to radiation and climate changes. The product has the advantages including light weight, high intensity, fire protection, heat insulation and nice processability etc.

· Advantages

  • A1

    Outstanding Waterproofing Performance

    No oil and water absorption enables the product to maintain stable insulating performance.

  • A2

    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.

  • A3

    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, this product has better physical strength.

  • A4

    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.

  • A5

    Excellent Soundproofing Performance

    Great soundproofing effectively reduces industrial noises.

· Applicable Scope

  It is widely used for the roof and wall heat insulation board, ceiling board, air channel of high rises and public buildings, the partition board of various vessels and fire prevention doors etc.
