Frequently Asked Questions
Why Was Asbestos Used in Building And Insulation Products?
The primary reason that asbestos was used in building
products was as a binder or filler material. It was cheap and
easily available. It is stringy and resilient, and thus made a
good binder. Its resilience also reduced the breakage of the
products between the factory and the worksite. In pipe covering
and other materials, asbestos created air pockets which provided
heat resistance.
Asbestos was marketed for its "fire resistant" qualities. In
reality, at approximately 1200 degrees, asbestos transforms into
an inert mineral. Other materials were available, even in the
1930's and thereafter, that could have been used (and, in fact,
were used) as substitutes for asbestos without any sacrifice in
product integrity or heat resistance. The asbestos industry
peddled asbestos as a "magic mineral," creating a demand for the
material, without advising of the dangers of asbestos. As a
result, thousands of American workers were injured.
