Galalio is a bioplastic material made from casein, a protein found in milk. It is a thermoplastic, meaning that it can be softened by heat and then shaped or molded. Galalio was first developed in 1909 by Wilhelm Krische and Adolph Spitteler in Germany. It was originally used as a substitute for ivory in items such as buttons, combs, and jewelry.

Galalio is a strong and durable material that is resistant to water and heat. It is also non-toxic and biodegradable. However, it is not as flexible as some other plastics, and it can be brittle if it is too thin.

Galalio is still used today in a variety of applications, including:

* Buttons

* Combs

* Jewelry

* Eyewear

* Electrical components

* Toys

Galalio is a versatile and sustainable material that has a wide range of uses. It is a good choice for products that need to be strong, durable, and water-resistant.
