KIMYA TPC ESD / Electrostatic Discharge Safe Filament
The Kimya TPC-ESD 3D filament belongs to the thermoplastic copolyester family: is an elastomer. TPC is obtained by copolymerization of two types of monomers: an ester (a rigid segment) and an ether (a flexible segment). Its “-ESD” formulation also provides protection against electrostatic discharge. It offers resistance to chemicals and to impacts and has a Shore hardness of 91 A. It can be used to print flexible, elastic parts. The Kimya TPC-ESD 3D filament is used in industry to produce connectors, sensors, measuring devices, etc. It has the following properties:
- Excellent flexibility
- Electro Static Discharge: protects against electrical discharge
- Easy to print
- Complies with the REACH standard
- Product Dimensions: 20.7 × 20.5 × 6 cm; 1.1 kg
