Asbestos can be made of a number of different minerals which are naturally resistant to heat and fire. Chrysotile is the most common of these minerals but anthophyllite, amosite, crocidolite, tremolite and actinolite have all been used as well. The minerals can be broken down into fibers that are then spun with cotton into yarn for fabric or added to products such as paperboard or building materials. It has been used for many types of products where fire resistance is desirable such as insulation, roofing shingles, brake linings and theater curtains.

Is asbestos a good insulator of heat?
Yes, asbestos is an excellent heat insulator. That was one major reason it was widely used in ships and in heating plants.
Does Sheetrock have fire rating by itself?
Yes, the average 1/2" thick board has a nominal 30 minute fire resistance.
What is the group name of asbestos?
Chrysotile asbestos (White) is a Serpentine, Amosite (Grunerite) (Brown asbestos, and Crocidolite (Blue) are Amphiboles
What light is a good example of a fire?
Fire is a good example of NATURAL light
When is too high a resistance not a good thing in a circuit?
Too high a resistance is always not a good thing in a circuit. That's what "too high" means.
What are the five properties of asbestos?
Heat resistance: Asbestos is able to withstand high temperatures without melting. Insulating properties: Asbestos is a good insulator against electricity and heat. Durability: Asbestos is strong and resistant to chemical damage. Flexibility: Asbestos fibers can be woven into fabrics without breaking. Fire resistance: Asbestos is highly resistant to fire and does not easily ignite.
Why did you use asbestos?
Asbestos was used due to its impressive properties. * Fire proof * Heat proof * Electrical resistance * Chemical resistance * Rot proof * Low cost * Abundance * etc
In what profession were asbestos suits originally worn?
Asbestos suits were originally worn in the profession of fire fighting because of its high heat resistance. Asbestos was banned later because exposure to it causes cancer.
What year was asbestos used in buildings?
Up until 1976 it was required in a lot of buildings where fire resistance was necessary.
Was asbestos used in fire proof safes?
Yes, asbestos was commonly used in fireproof safes to provide insulation and fire resistance. However, due to the health risks associated with asbestos exposure, its use in safes has been phased out in favor of safer alternatives.
What fire resistance matterial is no longer used due to its carcinogenicity?
Asbestos is a fire-resistant material that was commonly used in the past but is no longer used due to its carcinogenic properties. Exposure to asbestos has been linked to various health issues, including lung cancer and mesothelioma.
Why is asbestos fire resistant?
Asbestos is fire resistant because, as a silicate, it is basically a kind of rock and will not burn.
What is the one main function of asbestos?
There are several functions of asbestos, but probably the main one is fire-proofing. By the way, asbestos is a rock, and there are actually 5 different kinds. Only one of these can cause cancer.
What was asbestos used for in the 1970's?
In the 1970s, asbestos was commonly used in building materials such as insulation, roofing, and flooring. It was valued for its strength, fire resistance, and insulation properties. However, its use declined as the health risks associated with asbestos exposure became more widely recognized.
Did the National Gypsum Company make fireproof gypsum wall board with asbestos?
Yes, in the past, the National Gypsum Company manufactured fireproof gypsum wallboard that contained asbestos as a fire-retardant additive. However, the company has since stopped using asbestos in their gypsum products due to health concerns associated with asbestos exposure.
What chemical or physical properties make asbestos a good insulator?
Asbestos has high tensile strength and flexibility, allowing it to be woven into fabric or compressed into sheets, making it a good insulator. Its fibrous nature traps air pockets, which provides thermal insulation. Additionally, asbestos is resistant to fire, chemicals, and electricity, which enhances its insulating properties.
What element is fire resistant it's material no longer used due to its carcinogenicity?
Asbestos (particularly blue asbestos)
