casein plastic (thermoset, <plastic by property>, ... Materials (hierarchy name)) |
|
Note: Thermoplastic molding materials prepared from casein, a natural phosphorous-containing protein found in milk. While trying to make a waterproof coating in 1897, Adolph Spitteler and associate W. Krische of Germany discovered that casein becomes hard and insoluble when treated with formaldehyde. Casein plastics were used for small items such as buttons, beads, buckles, combs, fountain pens, umbrella handles, cutlery handles, and knitting needles; they are often pigmented to simulate ivory, horn, or tortoise shell.

| Chinese (traditional) ..... 以酪蛋白製成的熱固性塑膠鑄模材料。酪蛋白為存在牛奶中的含磷天然蛋白質。西元1897年德國的安道夫‧斯比特勒（Adolph Spitteler）與其助理W. 克利斯奇（W. Krische）在嘗試製作防水塗層的過程中，發現經甲醛處理的酪蛋白會變硬且不可溶。酪蛋白塑膠可用於製作小型物件，如鈕扣、珠子、皮帶扣、梳子、原子筆、傘柄、餐聚柄和織針。這些產品通常會經顏料染色，以模擬象牙、犀角或龜甲等。 |
