Otoscope device components made with medical-grade TPE

Expansion in handheld imaging technology has led to smaller and lighter otoscope systems, used in regular clinical practice, that make visual assessment faster and more efficient in healthcare facilities and mobile care settings.  As portable medical devices, otoscopes require materials that combine durability, safety, and ergonomic handling.

Industry standard and compliant advanced materials like thermoplastic elastomers (TPE) boost the performance of medical visualization devices.

Efficient material solutions for otoscope components

KRAIBURG TPE, a leading global manufacturer of TPEs and customized solutions for various industries, offers the high-performance THERMOLAST® H healthcare TPE materials, suitable for medical visualization technologies, including otoscope applications.

These otoscope materials are ideal for functional and user-facing components, including sealing elements, cable interfaces, buttons, soft-touch grips, housings, and flexible connections, enhancing device durability and user comfort. As TPE solutions specifically for low-risk, hand-held medical devices such as otoscopes, they enable compact device layouts while ensuring durability and comfort during repeated clinical use.

Multi-component processing and integration

The THERMOLAST® H healthcare series demonstrates excellent adhesion to polypropylene (PP) and polyethylene (PE). This delivers efficient multi-component injection molding and direct integration of soft-touch elements onto rigid housings. As TPE solutions for otoscope devices, this approach improves ergonomics, enhances sealing performance, and reduces assembly steps, thus promoting cost-efficient manufacturing.

Durability for long-term use

The THERMOLAST® H compounds assure dimensional stability, elasticity, and surface integrity in otoscope components that undergo repeated mechanical stress, cleaning, and sterilization. An optimized compression set supports long-term performance of seals, gaskets, and flexible interfaces, even after repeated use and sterilization cycles.

Color options and tactile performance

The THERMOLAST® H series allows colorable and translucent formulations. These options promote visual differentiation of controls and functional zones on otoscope devices, improving usability and clarity during operation. Meanwhile, the smooth, soft touch surface the compounds provide improves grip and handling comfort during extended examinations, enabling consistent device control.

Sterilization compatibility and safety

THERMOLAST® H materials are compatible with common sterilization methods, including autoclave sterilization at 121°C and ethylene oxide (EtO). The compounds are free from animal-derived ingredients, heavy metals, and other harmful substances, thereby ensuring safe use in reusable otoscope devices and accessories intended for close patient and clinician contact.
