The new heat-resistant composite filament PBT GF30 is based on polybutylene terephthalate with a fiberglass filler.
Polybutylene terephthalate (PBT, PBT) is a structural polymer with high heat resistance, strength and rigidity, as well as resistance to fuels and lubricants and most solvents, which is why PBT is widely used in the automotive industry, the production of household appliances and other electrical products, for example, automotive under — hood pipes, hair dryer housings and electric kettles.
At operating temperatures up to 150°C, the new composite with a 30% glass fiber content can withstand short-term heating up to 200°CWith and demonstrates high dielectric properties. During 3D printing, the material practically does not emit unpleasant odors. For optimal results in terms of interlayer adhesion, it is recommended to print at a temperature of at least 270°C with the work table heated to 110-130°C, preferably in a thermal chamber. There is almost no shrinkage of the material during printing. According to the developers, this is the most heat-resistant polymer material from non-hygroscopic ones.
“Durable… Just very durable! And very solid, ” summed up the CEO of Filamentarno! Ruslan Molchanov.
