Envalior Unveils Revolutionary PBT at K 2025 and The Battery Show North America

Introduction

Envalior has made waves in the engineering materials industry with the introduction of its innovative Pocan® PBT, presented at notable events such as K 2025 and The Battery Show North America. This new polybutylene terephthalate (PBT) combines sustainable practices with high-performance capabilities and is poised to transform various high-voltage applications.

Exceptional Properties of Pocan® PBT

Pocan® BFN4232ZHR S1 is engineered to exhibit remarkable elongation at break, superior tracking resistance, and hydrolysis resistance. It stands out in its class by being halogen-free and flame-retardant, making it ideal for critical applications. Crucially, it retains high electrical insulation, even under elevated temperatures, ensuring reliability in performance.

Application Areas

The new PBT is particularly suited for connectors in ultrafast charging stations for electric vehicles, operating at voltages of 800V and above. It also holds vast potential in AI data centers and as a secondary power supply in hybrid vehicles. Dr. Jochen Endtner, head of product development for Pocan®, emphasizes the material’s versatility, indicating that it can be utilized in various electrical components, especially within the burgeoning smart grid market.

Technical Advantages

The Pocan® PBT shines with its high elongation at break exceeding 2.5%, synonymous with polyamide compounds, contributing to increased toughness and energy absorption. This characteristic minimizes the risk of breakage under mechanical stress, making it an attractive material for various designs. Long-term testing confirms its resilience; the PBT maintains over 70% elongation at break even after 1,000 hours in rigorous conditions such as 85°C and 85% humidity.

Expanded Applications

Additionally, Pocan® BFN4232ZHR S1 meets stringent SAE/USCAR standards, offering high hydrolysis resistance that opens its application across various sectors historically reliant on polyamide. Such advancements provide designers greater freedom in creating components that require minimal wall thickness, thereby optimizing space while ensuring electrical safety.

The material also exhibits the best possible ratings under the Comparative Tracking Index (CTI A test), achieving a 600 rating—an industry benchmark for insulation performance.

Fire and Environmental Safety

Furthermore, Pocan® PBT's UL 94 certification V-0, at a specimen thickness of 0.75mm, demonstrates its superior flame resistance, adding another layer of safety in its applications. This is particularly vital in color-coded connectors, a common requirement in the design of cable harnesses.

Designed with occupational safety in mind, this PBT is free from halogenated substances and polyfluorinated alkyl substances (PFAS), ensuring safer handling during processing without the risk of harmful emissions.

Future Prospects

Envalior has ambitious plans to diversify its PBT line further by developing additional variants with different glass fiber content to optimize unique properties. New grades can be significantly enhanced for various applications including visual data marking using laser technology, advancing traceability and compliance.

Envalior's ongoing commitment to sustainability is further highlighted by the option of sourcing materials from renewable raw materials, such as bio-based butanediol.

Conclusion

As Envalior showcases its breakthrough materials at significant industry events, the introduction of Pocan® PBT could indeed set new standards in high-voltage applications, particularly in the electric vehicle and energy-efficient devices sectors. With its extensive property profile and applications, it stands on the brink of redefining the engineering materials landscape for years to come.
