Medical-Grade and Healthcare TPE for Metered-Dose Nasal Spray Bottles 

Self-administered medication often presents a challenge: ensuring accurate dosage. Metered-dose inhalers (MDIs), designed for patient use via inhalation, deliver a precise amount of medication to the lungs with each spray. MDIs are widely used to treat asthma and other respiratory conditions. The container closure system, which houses the pump, is designed to provide consistent medicine delivery. Incorporating advanced healthcare TPE materials, such as thermoplastic elastomers (TPEs), in components like seals and gaskets enhances drug delivery devices, ensuring precise medication administration and reliable operation.

KRAIBURG TPE, a global manufacturer of TPEs and customized solutions for various industries, offers medical-grade THERMOLAST® H series compounds for metered-dose nasal spray bottles, providing functional reliability for efficient and intuitive operation, as well as high-performance properties that meet medical device specifications, from safety and biocompatibility to lightweight build and material sustainability.

Material quality for sturdy components
The THERMOLAST® H series features an optimized compression set, ensuring that critical components such as seals, gaskets, and soft-touch actuator parts retain their shape and continue to function even after repeated use. This TPE solution for metered-dose nasal spray bottles provides a smooth, soft-touch surface that enhances handling comfort, resulting in convenient, accurate, and easy operation of the spray bottle.

Reliable adhesion in multimaterial designs
The THERMOLAST® H series showcases excellent adhesion to polypropylene (PP) and polyethylene (PE), widely used plastics in medical device housings, allowing soft functional elements to integrate seamlessly with rigid bottle components through multi-component injection molding. Manufacturers seeking effective pharmaceutical packaging solutions benefit from reduced assembly complexity, reliable mechanical bonding, and design flexibility.

Colorability for functional efficiency 
The THERMOLAST® H series is colorable and available in translucent formulations, providing clear visibility of liquid levels and enabling functional differentiation of components. The application of metered dose nasal spray bottles materials likewise bolsters device usability and accurate medication administration, improving treatment compliance and outcomes.

Material safety assured for critical applications
The THERMOLAST® H series complies with international standards and regulations. All raw materials are approved in accordance with (EU) No. 10/2011, GB 4806.7-2023, and (FDA) CFR 21. In addition, bio-compatibility testing has been conducted in accordance with ISO 10993-5 and GB/T 16886.5, ensuring the safe and reliable performance of the device. Free from animal-derived ingredients and harmful substances, the material is also compatible with sterilization methods such as autoclaving (121°C) and ethylene oxide (EtO), ensuring contaminant-free and safe use in sterile environments.
