Kraiburg TPE elastomers to light up cars, electronic devices

Waldkraiburg, Germany – Thermoplastic elastomers (TPEs) major Kraiburg TPE has introduced a light transmissible elastomeric material, particularly for use in consumer electronics and automotive interiors.

With target applications including EVs, smart home devices and consumer electronics, the ‘Light Effect TPE’ is claimed to “consistently deliver” reliability, and soft-touch properties that enhance product performance and appeal.

The advanced level of light transmissibility “enhances automotive and electronic components with an ambient glow,” said Kraiburg TPE, adding that the mouldable elastomer enables “versatile designs and limitless creative possibilities.”

The durable TPE, it stated, has a density of 0.89 ± 0.03 g/cm³ and a hardness of 60 ±5 ShA, while offering a tensile strength of 10 MPa and an elongation at break of 700%.

With a weathering resistance rating of DE 1.20 (350h), the halogen-free material (compliant with IEC 61249-2-21) maintains performance over a period of time, continued Kraiburg TPE.

The material, it said, “features UV resistance and optimised mechanical properties for long-lasting use, with a controlled level of emission and odor, thus making it suitable for automotive interiors.”

When integrated into EV dashboard panels, door trims, and footwells, the TPE provides ambient lighting for the cabin, with “a subtle glow [that] adds elegance while ensuring adequate illumination for night-time driving.”

For smart devices, meanwhile, the elastomer can be integrated into the device body to provide ambient lighting, including for a logo, backlit display, or indicator light.

The soft-touch surface is said to enhance user-experience in wearables, such as smartwatches, while a smooth finish “improves the comfort of handheld devices and personal appliances.”
