ASC CS220 WR WATER-REPELLENT CALCIUM SILICATE


  The insulation material is characterized with waterproof effect for outdoor applications,mainly used in under-ground piping system and special outdoor insulation.According to customers’requirements,the CS170 and CS220 could be made into whole water repellent type. 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. It can still remain its own property at the high temperature of 650℃: heat resistance and super-low chloride ion content, so it can have very good protection on peripheral steel pipes, resist deformation and have super-long service life.

· Advantages

  • A1

    Outstanding Waterproofing Performance

    No oil and water absorption reduces the safety hazard caused by medium leakage.

  • 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, ASC CS220 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's the preferred product for equipment pipelines and heat supply pipeline network systems in industrial fields such as electricity, petrochemical industry, metallurgy, construction, vessel, etc. It can also be used as the backing material for firebricks in various furnaces.
