Smart lock systems are electronic alternatives to mechanical locks, operating without physical keys. They use technologies like PIN codes, fingerprint recognition, RFID cards, Bluetooth or Wi-Fi, and voice control to provide secure, convenient, and remote access in homes, offices, apartments, and vehicles. To make operation more intuitive, manufacturers use thermoplastic elastomers (TPE), which simplify functions, improve control surfaces, and enhance visibility in low light, while keeping the locks reliable and easy to use.

KRAIBURG TPE, a global manufacturer of TPEs and customized solutions for various industries, offers Light Effect TPE, a light-transmissible material that creates an ambient glow. It combines aesthetics with performance and is suited for smart home devices, automotive interiors, and other electronic applications.

Illuminating features for function and style
KRAIBURG TPE¡¯s Light Effect TPE is tailored for components that emit light, providing subtle backlighting and illuminated indicators to enhance user engagement and device intuitiveness. It allows soft, diffused light to pass through, making it ideal for lighting keypads, buttons, or keyholes in low light, signaling lock status, marking touch-sensitive areas, and adding lighting accents. Available in black and colored variants, it gives designers control over illumination levels for both functional and aesthetic purposes.

Reliable performance and versatile applications
KRAIBURG TPE¡¯s Light Effect TPE compounds have a density of 0.89 ¡À 0.03 g/cm³, a hardness of 60 ¡À 5 ShA, and offer a tensile strength of 10 MPa with 700% elongation, providing the flexibility and durability needed for demanding applications. The material is weather-resistant, UV-resistant, halogen-free (in accordance with IEC 61249-2-21), and maintains its performance and shape throughout its service life. It bonds well with polypropylene (PP), making it suitable for smart lock systems, interior car lighting, light panel covers, gaming accessories, display panels, household appliances, consumer electronics, and smart home devices. It can also be reused during production to promote a more sustainable manufacturing.

Soft touch for precision and control
KRAIBURG TPE¡¯s Light Effect TPE has a soft-touch surface that gives smart lock devices a high-end, tactile finish. When used on frequently handled components, it improves comfort and control, resulting in smoother operation and a more polished device interface.
