Material solutions for electrified mobility systems.

Politem develops compounds for battery, charging and high-voltage applications where electrical safety, thermal performance and dimensional reliability come together.

From Battery Systems to Charging Infrastructure

E-mobility components operate at the intersection of electrical safety, mechanical protection, thermal exposure and compact design. Material selection must also consider processing, colour identification and long-term performance under changing environmental conditions.

TYPICAL APPLICATIONS

• Battery module components	• Cell holders and separators
• Battery covers and auxiliary housings	• High-voltage connectors
• Busbar holders and insulators	• Charging plugs and sockets
• Charging-station components	• Cable protection and routing
• Thermal-management components	• Sensors and control housings

Material and Technology Portfolio

Material families are selected according to voltage environment, temperature, mechanical loading, wall thickness and production process.

Material Platform	Relevant Technologies
PA6 and PA66	Reinforced, flame-retardant, hydrolysis-resistant, heat-stabilised and impact-modified solutions
PBT	Electrical insulation, dimensional stability, hydrolysis resistance and flame-retardant grades
PPA	High-temperature stiffness, dimensional control and reinforced solutions
PP	Lightweight flame-retardant, mineral-reinforced and recycled-content options for selected components
PC ABS	Impact performance, flame-retardant options and appearance for charging and electronic housings

Performance Priorities

Targets are defined for the exact component and cannot be reduced to a single material property.

• Electrical insulation and CTI	• Flame retardancy
• Glow-wire behaviour	• Thermal ageing
• Dimensional stability	• Low warpage
• Mechanical strength	• Impact resistance
• Hydrolysis resistance	• Colour stability and identification

Application Driven Development

Politem supports material development from initial requirement mapping through formulation, moulding trials and performance validation. Orange and other safety-identification colours are developed together with the required thermal and electrical property targets.

TESTING AND VALIDATION

Relevant testing may include flammability, glow-wire, CTI, mechanical, thermal, dimensional and colour evaluation. Customer-specific automotive, charging-infrastructure or mobility protocols are reviewed project by project. External test reports or certifications are identified separately from in-house results.
