  1. BAKELITE Ben Hastie, Daniel Bacon-Brown, Billy Martin, MaKenzie Ball MSE 404G Fall 2010

  2. BakeliteorPolyoxybenzylmethylenglycolanhydride • Among first synthetic plastics developed (1907) • Thermoset plastic • Formed via elimination reaction of phenol and formaldehyde • CAS number: 9003-35-4

  3. Producing Bakelite • Less flammable than celluloid • Dr. Leo Baekeland started the corporation around 1910 • Molding • Formula cooked until resinous • Thin sheets to harden • Ground (fillers) • Hot rollers • Ground • Molded with high heat and pressure • Casting • Modified formula to allow resin to be poured into molds • Ovens until polymerized and hard • Could be tinted or marbleized into more colors • These were sold as cylinders/blocks to jewelry makers • New technology after WWII led to injection-molding (less labor-intensive) leading way to a new generation of plastics

  4. Bakelite-Electrical Usage • Due to the fact the Bakelite has high electrical resistance, it was used in many electrical applications • Radio • All non-conducting parts • Automobile • Distributor Caps • Became unpopular to use because of its color

  5. Space Exploration • Bakelite was used as the heat shielding in the Galileo spacecraft, which was sent to Jupiter in 1989.

  6. Uses in weaponry • Very important in World War II • The US Government needed materials for weapons. • Bakelite was used because it was relatively cheap and lightweight compared to steel. It was also easy to make into complex shapes. • Bakelite was primarily used to make hand grenade casings and grips for machine guns. • Still used in some modern weapons. • Mostly magazine casings, but some grips as well. Bakelite magazine casing for modern machine gun

  7. Other Applications and Usages Today: • Porcelain Substitute • Billiard Balls • Dominoes • Pieces for Chess, • Checkers, and • Backgammon • Saxophone Mouthpieces • Whistles • Cameras • Solid-Body Electric Guitars • Rotary-Dial Telephones • Early Machine Guns • Appliance Casing • Jewelry ‘20s-’30s • Clocks, Radios, Kitchenware
