Polymaker PC-PBT Filament

Polymaker™ PC-PBT

Polymaker™ PC-PBT is a PC/PBT polymer blend which offers good heat resistance and toughness at low temperature (-20˚C/-30˚C). Polymaker™ PC-PBT also features good chemical resistance.

The Industrial range of products provide engineering grade materials to unlock the use of 3d printing in multiple industries for new applications. Industrial products can require specific equipment and skills.


Low Temperature Impact Resistance - Polymaker™ PC-PBT has a high resistance to impact. It also features an excellent low temperature toughness keeping more than 70% of its impact resistance at -30˚C.

Heat Resistant - Polymaker™ PC-PBT is an excellent choice for heat resistant applications, offering better heat resistance than a range of other material types and withstanding temperatures up to 140ºC.

Good Chemical Resistance - Polymaker™ PC-PBT is resistant to hydrocarbons, alcohols, organic acids, inorganic aqueous salts, and mild base and acid solutions. This makes them suitable for applications requiring resistance to intermittent contact with many lubricants, solvents, fuels, oils, cleaning agents, and other automotive-type chemicals.

Formulated For 3D Printing - Using Covestro’s Makroblend® family as its base material, Polymaker™ PC-PBT is specifically engineered for 3D printing to combine excellent mechanical properties and printing quality. Makroblend® is widely used in various industries. Enclosure and 100°C heated bed required; a heated chamber is highly recommended.

Uncompromised Quality - Polymakers leading quality control process and rigorous in-house testing ensure reliable printing and consistency across spools and batches.
