Recycled PBT (Polybutylene Terephthalate) is widely recognized for its mature and efficient application in manufacturing high-performance electronic connectors. These connectors play a vital role in ensuring electrical conduction and signal transmission in modern electronics. The demanding requirements for mechanical strength, electrical insulation, heat resistance, and dimensional stability make recycled PBT a highly suitable material in this field.

Recycled PBT offers high volume resistivity and dielectric strength, effectively preventing leakage or short circuits and ensuring safe performance in high-voltage or high-frequency environments. This makes it ideal for power adapters, communication devices, and industrial control boards.
PBT exhibits a high glass transition temperature (50–60°C) and can withstand heat deformation up to 200°C, making it suitable for soldering processes like wave soldering and reflow soldering. It maintains dimensional stability in the range of -40°C to 120°C, ensuring long-term reliable connection performance.
With excellent tensile, flexural, and impact strength, recycled PBT supports the frequent plugging and unplugging of connectors. Its surface hardness also resists wear, significantly extending service life in frequently used components like USB and HDMI ports.
Derived from post-consumer recycled PBT products such as discarded appliance casings and automotive parts, recycled PBT reduces dependence on petroleum and lowers carbon emissions. It is also 10–20% more cost-effective than virgin PBT, aligning with the electronic industry's focus on cost-performance balance.
With the growing global emphasis on sustainability in electronics, the use of recycled PBT in connector applications is rising. According to industry reports, the global recycled PBT connector market reached USD 1.2 billion in 2023 and is expected to grow at a CAGR of 8% over the next five years. Leading connector manufacturers are integrating recycled PBT into their green supply chain strategies.
Despite PBT’s excellent all-around properties, its ester bonds can reduce stability in certain chemical environments. However, through targeted modifications, these limitations can be addressed, enhancing its suitability for more demanding applications.
