The Ceramic Blanket has the same excellent chemical stability compared with its raw materials. It has excellent strength before and after heating. It has superior acoustic as well as thermal insulation characteristics. The wide range of available densities allow for the most eﬀective deployment of the superior thermal characteristics in a wide variety of applications.

- For some applications, it is possible to use Ceramic Blanket above its classiﬁcation temperature (shrinkage is 5% at 1500°C).
- Low heat storage.
- The combination of long spun ﬁbres and the needing operation produce tough, resilient and strong blankets which resist tearing both before and after heating.

- It is highly unlikely that the products will cease signiﬁcant amounts of dust during normal handling.
- Dust control measures will rarely required in circumstances involving the fabrication of products from the material.
- However according to good working practices the production of debris should be minimized. Use suction where possible to collect dust.
- Clean waste with HEPA ﬁlter vacuum cleaner.
- Observe emission limits. (See Section 8) store in a dry place.
