Long-term operation test of RPCs for the OPERA experiment

Bakelite RPCs will be used to instrument the iron yoke of the muon spectrometers. We present the results of long-term (greater than 6 months) streamer operations of real size OPERA RPCs at cosmic rays fluxes. Given the very low rate observed in the

Bakelite First Synthetic Plastic

Versatile and readily molded, Bakelite found wide use in the expanding consumer economy and opened the door to an era of synthetic materials. Used by Baekeland around 1909, 'Old Faithful' was kept by the General Bakelite Corporation and its successor, Union Carbide Co., which donated it to the Smithsonian Institution in 1983.

Toxic Plastics: Bakelite, the Silent Killer| Natural Health

 · The risk with formaldehyde comes from long-term exposure in enclosed environments with poor air circulation. The people most at risk (just like with asbestos) were those who manufactured it. Formaldehyde is commonly kept as a liquid dissolved in water, and is a precursor to PF resins such as Bakelite.

Bakelite

Abstract. In 1907 Bakelite, the first synthetic plastic was produced. The rapid growth in global plastic production, for many reasons, initiated in 1950s. The annual production of plastics increased by 200 folds over the next 65 years to over 400 million tons annually.

You would think with the history of Ballistol, where it's made, and who it was originally made for that they would have tested it certainly on Bakelites or somebody would have said don't use it, it will take the ink stamps off?

Plastic

The world's first fully synthetic plastic was Bakelite, invented in New York in 1907 by Leo Baekeland, who coined the term plastics. Many chemists have contributed to the materials science of plastics, including Nobel laureate Hermann Staudinger , who has been called "the father of polymer chemistry ," and Herman Mark , known as "the father of polymer physics ."
