Thermoplastic Copolyester is a class of TPE that has slightly different properties to the rest of the TPE family. TPU is also a member of the TPE family that is listed separately on Filaments.directory as it has slightly different properties.
Both TPC and TPU are Copolymers of the TPE family. A copolymer is a polymer that is comprised from two or more monomers. Copolymers are a way of enhancing the properties of a polymer by adding other monomers. TPC is a block copolymer, meaning that the two monomers are part of the same polymer but do not mix together. This results in the material having 'soft' and 'hard' regions and is why it can be repeatedly heated and processed.
TPC are high performing polymers that combine the properties of thermoplastics and rubbers. TPC demonstrates high structural strength as well as elasticity and impact resistance. TPC can be elongated significantly before it will deform and break. Because of its impact resistance and combination of tough and flexible properties, TPC is commonly used for applications like solid tires.
TPC is generally printed around the 200°C to 235°C. Like all members of the TPE family, TPC's extremely flexible nature means that it is prone to buckling in the feeding mechanism of your 3D printer, leading to jams. The problem for TPC is less than for TPE as it is slightly stiffer. Like most soft, flexible filaments, TPC adheres very well to itself.
TPC is a great option for 3D printing that requires the flexibility and elasticity of TPE but needs higher impact resistance. Here at Filaments.directory you can select the right TPC filament using our constantly updated list of suppliers and our comprehensive search tool!
