What Are the Key Properties of Pocan® PBT?

PBT is a semi-crystalline thermoplastic with a melting point of approximately 220°C. Its material characteristics make it suitable for applications requiring stable dimensions and consistent performance.

Depending on the grade, Pocan® PBT compounds can provide:

• High mechanical strength and stiffness

• Good dimensional stability

• Low water and moisture absorption

• Good chemical resistance

• Excellent electrical insulation properties

• High tracking resistance

• Flame-retardant performance

• Improved resistance to hydrolysis

• Enhanced impact and toughness

• Reduced warpage

• Laser transmission welding capability

The use of glass fibres, minerals and other modifiers allows these properties to be tailored to specific component requirements.

When Should Glass-Fibre Reinforced Pocan® PBT Be Used?

Glass-fibre reinforced PBT is widely used when higher stiffness, strength and dimensional stability are required.

The Pocan® portfolio includes different reinforcement levels, making it possible to align stiffness, strength and processing behaviour with the technical needs of the component.

Glass-fibre reinforced Pocan® grades can be considered for:

• Electrical connectors

• Terminal blocks

• Automotive electrical components

• Sensor housings

• High-voltage components

• Structural and functional parts

• Components requiring high dimensional stability

PBT's low moisture absorption can be particularly advantageous in applications where stable dimensions and consistent electrical performance are important.

Which Pocan® PBT Grades Support Flame-Retardant Performance?

The Pocan® portfolio includes a wide range of flame-retardant PBT compounds for electrical and electronic applications.

Both halogen-containing and halogen-free flame-retardant PBT solutions are available for selected applications. These materials can combine flame resistance with mechanical strength and electrical insulation properties.

Potential applications include:

• Electrical connectors

• Terminal blocks

• PCB components

• Circuit protection components

• Electrical housings

• Capacitor housings

• Surge protection device housings

• High-voltage and low-voltage connectors

Selected Pocan® flame-retardant grades provide high CTI performance and are designed for applications where electrical insulation and flame resistance are critical.

Which Pocan® PBT Grades Are Suitable for Hot and Humid Environments?

Standard PBT can be affected by prolonged exposure to elevated temperature and humidity. For applications operating in hot and humid environments, Pocan® includes specialised hydrolysis-resistant PBT (HR and XHR) grades.

These materials are designed to improve long-term performance under demanding environmental conditions and can help retain mechanical properties over extended periods.

Hydrolysis-resistant Pocan® grades can be considered for:

• Automotive under-the-hood applications

• Components exposed to heat and humidity

• Electrical housings and covers

• Electrical components operating in demanding climates

• Applications requiring improved resistance to hydrolytic degradation

Selected HR and XHR grades are available with different levels of glass-fibre reinforcement and can provide a balance of mechanical performance and resistance to hydrolysis.

Which Pocan® PBT Grades Are Relevant for High-Voltage and E-Mobility Applications?

The rapid development of electric vehicles and high-voltage electrical systems is creating increasingly demanding requirements for insulating materials.

Pocan® PBT compounds can be used in applications that require a combination of electrical insulation, high CTI performance, dimensional stability, mechanical strength, hydrolysis resistance, stable processing and colour stability.

Selected Pocan® grades are designed for low- and high-voltage connectors and insulating components used in automotive and industrial electrical systems.

Specialised grades combine flame retardancy, high CTI performance, improved hydrolysis resistance and mechanical properties. The portfolio also includes materials designed for applications requiring stable orange colouration and laser marking.

Halogen-Free and PFAS-Free Pocan® Solutions

The development of new electrical and electronic systems is increasing demand for materials with specific regulatory and sustainability profiles.

Pocan® includes selected halogen-free flame-retardant and PFAS-free grades, including materials designed as alternatives to established thin-wall V-0 flame-retardant solutions.

Depending on the grade, these materials can offer a combination of:

• Flame-retardant performance

• High CTI

• Mechanical strength

• Good surface appearance

• Thermal stability

• Electrical insulation

• PFAS-free formulation

Potential applications include connectors, terminal blocks, PCB components and other electrical and electronic components.

Can Pocan® PBT Be Used for Laser Transmission Welding?

Selected Pocan® grades are available with improved laser transparency for laser transmission welding applications.

Laser welding can enable reliable joining of plastic components and is particularly useful for housings and components requiring clean, efficient and precise assembly.

Laser-transparent Pocan® grades can be considered for:

• Electrical and electronic housings

• Welded covers

• Complex technical components

• Components requiring sealed or robust welded joints

Selected grades also combine laser transparency with hydrolysis resistance for applications exposed to hot and humid environments.

Pocan® PBT Blends

In addition to standard PBT compounds, the Pocan® portfolio includes different PBT-based blends, including PBT/PET, PBT/PC and PBT/ASA materials.

These blends are designed to modify the performance profile of conventional PBT and can be selected when specific requirements for toughness, dimensional stability, surface quality, warpage or other properties need to be addressed.

PBT/ASA blends, for example, can be considered for components with complex geometries where reduced shrinkage and warpage are important design considerations.
