Electromobility is driving technological advancements to enhance safety features of vehicles, as well as render more efficient, safe, and comfortable driving. Along with enhanced accessibility to charging infrastructure, battery management systems, the heart of every vehicle, are also advancing.

Connectors and plugs play a vital function in battery management systems in order for batteries to operate efficiently, safely and to last for an extended period of time. These components ensure an uninterrupted supply of electrical energy while the vehicle is in operation and keep the battery charged.

It is critical, therefore, for the selection of advanced materials that will provide top-tier performance while simultaneously safeguarding plugs and connectors from fire hazards. 

Thermoplastic elastomers (TPEs) are safe, versatile, and long-lasting materials that can be used in battery charging system plugs and connectors.

KRAIBURG TPE, a globally recognized TPE manufacturer of thermoplastic elastomer products and custom-engineered TPE solutions, provides safety-compliant TPE compounds in a range of hardness suitable for connectors and plugs.

AD1/CS series – for good adhesion to thermoplastics

Selected TPE compounds from KRAIBURG TPE have been certified as meeting the UL94HB flammability standards, which specify how quickly a material will burn once ignited, to reduce the risk of a fire.

One of these select TPEs from KRAIBURG TPE that is UL94HB-certified is the AD1/CS series of compounds.

It has good compression set and adhesion to polar thermoplastics such as ABS, PC, PC/ABS, ASA, SAN, and PBT via the injection molding and extrusion processes, allowing for various design possibilities.

It is available in both natural and black colors and is suitable for overmolding in plug applications.

FR2 series – featuring high flame retardant properties

KRAIBURG TPE’s FR2 series of compounds is proven to be stable in temperatures up to 60°C and humidity levels of 75%. It displays self-extinguishing properties and does not emit burning droplets.

It is available in a variety of hardness with UL 94 V-0 (1.5 mm) certification and classification according to IN EN 45545-2 R22/23 HL3. The TPE compounds are halogen-free according to IEC 61249-2-21 criteria, and are silicone-free.

The FR2 series of compounds, which is available in both black and natural colors, adheres well to PP and has no interaction with copper. 

It is recommended for plug and connector applications in high voltage battery charging systems.

Sustainability successes of our TPE

Besides the materials for applications in connectors and plugs, KRAIBURG TPE’s recent sustainability innovations include a specially developed material solution for consumer, and industry applications comprising post-consumer recycled (PCR) and post-industrial recycled (PIR) content.
