Ethyl Cellulose (EC)
Ethyl Cellulose is a thermoplastic, further classified as a cellulosic plastic.
The properties of Ethyl Cellulose include eleven common variations. This page shows summary ranges across all of them. For more specific values, follow the links immediately below. The graph bars on the material properties cards further below compare Ethyl Cellulose to: cellulosic plastics (top), all thermoplastics (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.
