Custom Materials for Medical Applications

Noise absorption, insulation, and thermal control solutions for the Medical Industry

Medical respirator with medical grade insulation for noise reduction in a hospital setting

Since the inception of Polymer Technologies, we've been supplying foam to various medical equipment manufacturers to mitigate acoustic energy generated within their products.

Our medical applications include but are not limited to oxygen concentrators, blood analysis equipment, thrombosis control, motorized hospital beds, and CPAPs and BiPAPs for respiratory therapy and obstructive sleep apnea.

Acoustical Absorbers for Equipment Enclosures

Cleanliness, usability, and aesthetics all play an integral role in developing medical equipment enclosures. Covers or shrouds made of plastic and metal protect critical components of devices such as oxygen concentrators, blood analyzers, and MRIs, but shielding internal parts doesn’t always absorb the noise produced during operation.

Acoustic insulation can be used to reduce airborne sound, structural resonance, and increase the noise blocking potential of these enclosures, improving patient comfort and equipment operability.

POLYDAMP® Acoustic Foams and composites developed with damping or barrier materials are suitable for medical grade applications. Custom molded polyurethane like POLYFORM® Molded Foam can also be developed to increase acoustic absorption and improve the performance of equipment. Often, considering a molded foam solution at the inception of a product is the best way to ensure equipment efficiency and operability.

Custom Molded Foam Materials for Blowers, Motors, and Pump Housing

Molded foam solutions for medical motors, blowers, and pumps

Patient and operator comfort is crucial when creating medical equipment. The components within devices like oxygen concentrators and CPAP machines include blowers, compressors, and motors that have the potential to produce uncomfortable levels of noise, vibration, and heat that plastic and metal housings alone cannot mitigate. Standard absorptive materials like acoustic foam can be used in addition to barrier and damping materials, but some projects call for custom foam parts. Polymer Technologies develops innovative energy management solutions for medical equipment with POLYFORM® Molded Foams.

Using a molded foam solution enables medical manufacturers to think inside the box in new ways. Molded foam can eliminate the need for fasteners, screws, and parts while creating a more streamlined design that prevents airborne noise and isolates vibration. Another advantage is that molded foam can take the place of parts, allowing designers to develop pathways for wires, vents, and intake valves.

We worked with a manufacturer of respiratory medical devices to help them reduce noise and in the process replaced 37 parts including isolation mounts and 2-D acoustical insulators. Air paths created with plastic were replaced with one molded part. Molded foam enables bold design possibilities to come to life.

Noise Insulation for Intake and Exhaust Plenums

Sound absorbing solutions for intake and exhaust plenums in medical equipment

Helping patients breathe easier often requires the use of oxygen concentrators and respirators that can be loud and uncomfortable to use. Molded foam solutions can enable medical manufacturers to improve air flow control for medical applications and cooling components.

POLYFORM® Molded Foams afford product designers the ability to create noise absorptive components from medical grade foam. Molded foam solutions can also be used to eliminate the line of sight inside devices while maintaining an absorptive air path for intake and exhaust plenums. Traditional 2D acoustic foam can be used for noise insulation as well, but the right decision depends on the needs of the manufacturer.
