New Covestro medical polycarbonate pushes the boundaries of heat resistance

Overmolding polycarbonate with liquid silicone rubber (LSR) is commonly used to produce respiratory masks and other medical devices requiring molded-in seals. Using a polycarbonate made for higher temperatures in silicone overmolding can help to more than double production volumes due to shorter cycle times.

For 50+ years, healthcare customers have relied on our expertise and polycarbonate solutions. 

We continue to look for opportunities to provide added value to our customers. With this in mind, we formulated a polycarbonate made for higher temperatures in silicone overmolding to help our customers more than double production volumes in the same amount of time due to faster curing.

Apec® 2045 offers the highest heat resistance    in our medical polycarbonate portfolio. In addition, it offers a mix of properties that helps ensure high quality, performance and appearance for respiratory masks and similar medical applications with molded-in seals. 

Furthermore, Covestro experts support our customers every step of the way, for example, helping them calculate possible savings when switching to this material. 

Covestro formulated Apec® 2045 polycarbonate for higher temperatures in silicone overmolding.

Apec® 2045 high-heat copolycarbonate designed for medical devices with molded-in seals and healthcare applications requiring hot air sterilization at up to 180 °C.
