Protecting medical professionals and patients from a range of health and safety risks is the number one priority for the medical sector. Ensuring the right quality of Personal Protective Equipment (PPE), such as surgical caps, booties, surgical gowns, and face masks, is essential. Antioxidants for polyolefins enable nonwoven manufacturers to reduce filament breakage during polymer processing and support smaller pores between fibers for better high-performance filtration required for essential medical applications.

Our antioxidants for sterile medical applications are formulated to improve the stability of polymeric materials and promote consistent melt viscosity in polymers to meet the evolving needs of PPE manufacturers.


Polyolefin-based products used in medical applications can be sterilized via different methods including gamma irradiation. Selecting the proper stabilization technology is paramount to ensure the polymer is correctly protected, as polyolefins are sensitive to gamma irradiance and subject to color modification (yellowing), physical property degradation (brittleness) and loss of thermal stability. Similarly, SBR used in applications requiring heat must also be correctly protected. Heat and oxidation can cause cracking, charring, and color fading. Antioxidants for latex-related applications reduce the risk of oxidation and improve durability to prevent cracks and breaks in essential safety products. 

Our antioxidants work exceptionally well in polyolefin and latex applications to improve durability and ensure the safety of medical professionals. 

Today’s manufacturers continue to rely on plastics for a variety of packaging solutions. In food applications, light can affect the contents of products within transparent packaging, impacting a product’s shelf life or safety.
