Why can't asbestos-free calcium silicate insulation contain asbestos

Why can't asbestos-free calcium silicate insulation contain asbestos

Asbestos refers to silicate mineral products with high tensile strength, high flexibility, resistance
to chemical and thermal erosion, electrical insulation and spinnability. It is a general term for naturally
occurring fibrous silicate minerals. Under the jurisdiction of 2 categories of a total of 6 minerals (serpentine
asbestos, hornblende asbestos, actinite asbestos, direct amphibole asbestos, iron asbestos, tremolite
asbestos, etc.). Asbestos is made up of fiber bundles, which in turn are made up of very long and thin
fibers that can separate from each other. Asbestos has a high degree of fire resistance, electrical insulation
and heat insulation, is an important fire, insulation and thermal insulation material. However, because asbestos
fibers can cause asbestosis, pleural mesothelioma and other diseases, many countries have chosen to completely
ban the use of this dangerous substance.

On October 27, 2017, the World Health Organization's International Agency for Research on Cancer published a
preliminary list of carcinogens for reference, asbestos (in various forms, including actinite, ferrugite, amphibole,
chrysotile, chrysotile, tremolite) in the list of a class of carcinogens.


Regulations in the United States allow products to contain asbestos as long as they contain less than 1% asbestos.
The most common asbestos-containing products produced today are brake pads, roofing materials, vinyl shingles,
automotive clutches, cement pipes, household insulation, corrugated panels, and custom pot-sealing.


Therefore, in our calcium silicate insulation materials, including 650 degrees calcium silicate board, 1000 degrees
calcium silicate tube and shell products, since 1992, it has been prohibited to add asbestos components, the use of plant fiber,
wood fiber and other alternatives, asbestos-free high temperature resistant calcium silicate board is exported to Europe, Southeast
Asia and other regions
