Thermosetting Polyester Applications And Properties
Polyimides are another types of polymers that avaliable as both thermoplastic and thermosetting. But the thermosetting polyimides are much more important because of their properties. In here, we explain these properties of polyimides and applciations of them. Also you can find properties of a specific kind of polyimide polymer.
Thermosetting polyimides are renown with their excellent thermal and chemical resistance properties. Because of that, they are much more important from thermoplastic one. In market, thermosetting polyimides have commercial names as Kapton and Kaptrex. Because of these characteristic properties, polyimides are used in such applications like below;
This material constitutes chemicals that; pyromellitic dianhydride (C6H2(C2O3)2) and 4,40-oxydianiline (O(C6H4NH2)2). These starting materials are mixed in condensation polymerization process to obtain polyimid thermoset. Polyimides have bigger elongation value compared with other thermosets which is 5% according to original shape. It is very high around average thermoset values, but it can be called as brittle material. Tensile strength of this polyimid material is around 80 MPa and modulus of elasticity of this polyimid material is around 3200 MPa.
These are the general characteristics of polyimide thermosets. Do not forget to leave your comments and questions about applications and properties of polyimides below. Your precious feedbacks are very important for us.
