Keep in mind, PVC board is just not particularly sturdy on its own, so it will need a foundation or assistance process to stop bending or breaking.
PVC was synthesized in 1872 by German chemist Eugen Baumann soon after extended investigation and experimentation.[12] The polymer appeared like a white sound within a flask of vinyl chloride that were remaining with a shelf sheltered from sunlight for four weeks. Within the early 20th century, the Russian chemist Ivan Ostromislensky and Fritz Klatte in the شيش حصير German chemical firm Griesheim-Elektron equally tried to implement PVC in professional products and solutions, but difficulties in processing the rigid, occasionally brittle polymer thwarted their efforts.
