Acrylic elastomer is a general term for a type of synthetic rubber whose primary component is acrylic acid alkyl ester (ethyl or butyl ester). [3] Acrylic elastomer possesses characteristics of heat and oil resistance, with the ability to withstand temperatures of 170–180 °C.

The "serpentine" and "stone" of the pillars are made of celluloid glued to wood. Assorted tortoiseshell celluloid guitar picks. Most movie and photography films prior to the widespread move to acetate films in the 1950s were made of celluloid. Its high flammability was legendary since it self-ignites when exposed to temperatures over 150 °C in ...
1941 Acrylic fiber. Acrylic fibers are synthetic fibers made from a polymer Polyacrylonitrile with an average molecular weight of ~100,000, about 1900 monomer units. To be called acrylic in the United States, the polymer must contain at least 85% acrylonitrile monomer. Typical comonomers are vinyl acetate or methyl acrylate.
While the company closed its East Liverpool, Ohio, plant, which meant leaving the city where it was founded in 1871, it's still made in America — but in Newell, West Virginia. Amazon Crayola Crayons
