Thanks to their lightweight, impact, chemical and water resistance as well as hygienic qualities, styrenics polymers have been widely used in medical and testing equipment. Key applications include test tubes, petri dishes, and devices for the transportation of pharmaceutical goods such as vaccines. Styrenics are also used in drug delivery devices such as inhalers, providing flexible and cost-effective solutions. It is estimated that 80% of petri dishes and around half of medical inhalers and drug delivery devices are made using styrenic polymers.

Allowing the use of disinfectants on their surfaces, styrene-based materials enable the reuse of medical devices which would otherwise need to be disposed of. This means waste is significantly reduced, maximizing the value and sustainability of medical equipment. Styrenic-based materials also contribute to the safety of these applications as they are resistant and not susceptible to breaking compared to alternatives (e.g. glass).
