CompoundOne sells PBT (polybutylene terephthalate) and ABS (acrylonitrile / butadiene / styrene) under the trade name Compadur®.
Polybutylenterphtalates (PBT) are semi-crystalline plastics which are characterized by high strengths, stiffnesses and very good dimensional stability. They are low in creep, good impact strength and high resistance to friction and wear. Other features include:
Resistance to acids and many solvents
Low water absorption
Good electrical properties
Low thermal expansion
Typical application temperatures are between -50 and + 150 ° C. They are also good to glue and weld.
These properties result in frequent applications in vehicle construction and the electrical industry, e.g. as a housing or plug connector.
Acrylonitrile-butadiene-styrene copolymers (ABS) are amorphous thermoplastics, which are used more than 50% in the automotive and electrical industry. The preferred properties are:
High heat resistance
Continuous temperature of 85-100 ° C
High surface hardness Scratch resistant surfaces
Good impact strength
Good flowability
ABS is very good for galvanizing.
Because of its low resistance to external weathering, ABS is used primarily for indoor applications.
