Polybutylenterephthalate (PBT) belongs to the group of technopolymers. It is a rather unusual plastic for the furnishing sector.
This type of polyester is used as insulation in the electronics industry, as it combines a high level of sturdiness with resistance to heat.
It has a crystalline structure and is resistant to most chemicals.
If we also want to name the product for which it has been used, we can say that: “The goal for the seat of the BCN stool was to find a material that provided excellent flexibility without deflecting too much under body weight.”
