Treed PC PBT GF

The PC PBT GF filament from Treed Filaments is an affordable engineering filament with superior mechanical strength and dimensional stability thanks to the uniform distribution of high-quality glass fibers achieved through precise mixing and strict quality control. Its anthracite grey color provides an attractive finish, and it is designed to be printed on open printers without the need for a heated chamber. This filament is also very affordable, making it an excellent choice for cost-effective, high-performance 3D printing.

The PC PBG GF filament from Treed Filaments offers excellent mechanical properties, with a tensile strength of 78 MPa, a tensile modulus of 6100 MPa, and a flexural modulus of 6000 MPa. It provides good impact resistance, with Charpy impact values of 16 kJ/m² at 23 ºC and 8 kJ/m² at -30 ºC. As far as thermal performance, the filament offers a thermal conductivity of 0.20 W/m-ºC and a heat deflection temperature (HDT) of 156 ºC at 0.45 MPa and 120 ºC at 1.8 MPa, making it suitable for high-performance applications.

PC-PBT filament with glass fibers combines the impact resistance of polycarbonate, the chemical resistance and good lubrication of polybutylene terephthalate (PBT), and added stiffness from glass fibers, making it ideal for high-strength, durable applications in the automotive, aerospace, electronics, and industrial sectors. Its other advanced features sich as thermal stability, chemical resistance, dielectric strength, and flame retardancy make it suitable for components exposed to high temperatures, chemicals, and mechanical stress, and a great substitute for PA GF in certain applications.
