Question

Bakelite is fire resistance material or not​

Answer 1

Answer:

New Bakelite® FoamSet Materials Provide Improved Fire Resistance Through Lighter Weight and Proven Bakelite Molding Compounds.

Explanation:

Bakelite was the first FRP discovered by Dr. Baekeland. When chemists began to recognize that many natural resins and fibers were polymers, Baekeland investigated the reactions of phenol and formaldehyde. He first produced a soluble phenol-formaldehyde resin called “Novolak,” which never became a market success. He then turned to developing a binder for asbestos, which, at that time, was molded with rubber. By controlling the pressure and temperature applied to phenol and formaldehyde, he found in 1905 that he could produce a hard moldable material, the world’s first synthetic plastic, namely, Bakelite. The development of FRP for commercial use was being extensively researched in the 1930s. In the United Kingdom, considerable research was undertaken by pioneers such as Norman de Bruyne. It was of particular interest to the aviation industry [6]. Mass production of glass strands was discovered in 1932 when Games Slayter, a researcher at Owens-Illinois, accidentally directed a jet of compressed air at a stream of molten glass and produced fibers. Originally, fiberglass was a glass wool with fibers entrapping a great deal of gas, making it useful as an insulator, especially at high temperatures.

A suitable resin for combining the “fiberglass” with a plastic to produce a composite material was developed in 1936 by DuPont. Peroxide curing systems for the resins were used by then. With the combination of fiberglass and resin, the gas content of the material was replaced by plastic. This reduced the insulation properties to values typical of the plastic, but now for the first time the composite showed great strength and promise as a structural and building material. Many glass fiber composites continued to be called “fiberglass” (as a generic name) and the name was also used for the low-density glass wool product containing gas instead of plastic.
