Medical Grade of Polyacetal Iupital™ MA Series

The Iupital MA series meets the quality and regulatory requirements for medical materials, and is suitable for applications such as drug inhalers for COPD and asthma, injection devices such as insulin pens, and parts for medical devices.

The MA series is available in a range of standard, high-flow, high-rigidity, and low-friction grades, enabling greater design flexibility for medical devices and equipment, which are becoming smaller and lighter.

In particular, the low-friction grade MAL20 has greatly improved sliding performance with POM. In the past, combining POM parts would generate squeaking noise and friction, so designs would combine different materials in order to avoid these issues. MAL20 suppresses friction and wear, even when combined with ordinary POM, achieving quiet, smooth movement, which greatly improves comfort when used in medical devices.

In addition, with the MA series, we will offer a coloring masterbatch for color mixing. We support parts design not only in terms of physical characteristics, but also in terms of visual design.
