PBT is a linear thermoplastic saturated polyester polymer containing ester groups in the main chain. Its chemical name is Polybutylene terephthalate, or PBT for short. It is a polymer similar to PET resin.
Main features: (1): Non-reinforced grades are tough and flexible, with strong resistance to brittleness (2): Dimensional changes during use are very small, which is very good in terms of molding stability and dimensional accuracy Excellent high-reliability material (3): There are flame-retardant grades (94HB) and self-extinguishing grades (94-V-0, V-2) recognized by UL standards, and its electrical properties have the highest value among thermoplastics (4 ): It has excellent long-term chemical resistance. At room temperature, except for drugs other than strong alkali, there is almost no performance degradation in it for a long time. (5): Very low water absorption, in a wide range of temperatures and Long-term use in the humidity range can also maintain excellent electrical properties (6): Not only the non-reinforced grade, but also the reinforced grade has very good fluidity and excellent molding processability (7): The surface of the molded product is very smooth, with low coefficient of friction. Due to the small amount of friction generated, it is suitable for applications that require friction and wear properties (8): By adopting the technology of fusion with other polymers, a polymer alloy that meets various performance requirements has been developed< /p>The following are the physical properties of Japan-Polyplastics DURANEX PBT C5315N
