Polybutylene Terephthalate - PBT

Joint tailored development with Mitsubishi Chemical Corporation

PBT is used especially for valve parts, plug connectors and electrical/electronic components, but also for pump housings and wheels, household appliance components, headlight housings and automotive components.

Clear advantage over standard materials in powder bed fusion

Compared to PA12 and PA11, PBT has better mechanical properties and much lower moisture absorption, as well as higher heat resistance. In a joint development with Mitsubishi Chemical Corporation, AM Polymers has developed a PBT material which is characterized by good processability and good mechanical component properties comparable to injection molding.

No need for high temperature system

Unlike other PBT powders, no high-temperature equipment is required for processing ROLASERIT®    PBT-01. The material can be processed on all common standard systems for powder bed fusion. Hence, this material is available on the market without restrictions.

Ductility that pays off

ROLASERIT® PBT-01 has mechanical properties corresponding to typical injection molded PBT materials. In addition, it has a high elongation at break of 15 % compared with other available powders, with good layer-to-layer bonding in the direction of building. As a result, even finer structures can be produced without the risk of damage when unpacking or blasting.

Benefits of ROLASERIT® PBT-01

• High performance and ductility of up to 15 %
• Suitable for series production
• Easy processing & postprocessing (smoothing)
• Economic recycling rate of 30 %
• Superior Young`s Modulus up to 2,650 MPa
• Higher electrical resistivity compared to injection molding
• Outstanding surface quality without post-processing
• Natural / White and dark grey colors available
• Carbon fiber (6,200 MPa modulus) and glass fiber (3,900 MPa modulus) version available

Applications of PBT-01

• Automotive interior / exterior
• Fluid / water pumps
• Medical / pharmaceutical equipment
• Electronic & variety of industrial goods
• Technical components
• Housings, connectors i.e. for electronic unit
• Alternative to PA 12 with glass beads with low refresh rate
