Covestro polycarbonate: Like a breath of fresh air

Ventilation systems use durable Makrolon® polycarbonate

Like a breath of fresh air

Some people with respiratory insufficiency can go about activities with simple oxygen therapy. Others have more serious conditions that require mechanical ventilation administered by qualified, trained personnel.

Breathe Technologies Inc. offers respiratory therapies intended to improve quality of life. Because it is committed to bringing the highest-quality devices to market, the company needed durable, lightweight and long-lasting materials for components of its portable ventilation products.


The Breathe Pillow Interface™ delivers ventilation therapy by breathing for a patient. Unlike other respiratory devices, the design is slim and low profile. A Sizing Gauge helps patients select the optimal interface size. Both components required a durable, lightweight and biocompatible material.


For its two portable, wearable ventilation systems – the Non-Invasive Open Ventilation (NIOV)™ device and the Life2000h™ ventilator for life-support patients – Breathe Technologies Inc. utilized Makrolon® 2858 polycarbonate. The patient interface and sizing gauge are injection molded from this polycarbonate grade, which is acceptable for ETO and steam sterilization at 121 °C and is biocompatible according to many ISO 10993-1 test requirements, making it an ideal choice for medical devices.
