Antioxidants are necessary to avoid polymer ageing and degradation. Shear stress, oxygen, mechanical loading are responsible for polymer degradation, loss of mechanical and aesthetical properties. Antioxidants help to combat the chemical reactions generated by these factors. Choosing an antioxidant is not only a question of performance. The latest technologies offer superior polymer stabilization but also help the whole polymer value chain to improve its business profitability.

What are polymer antioxidants?

What is the purpose of polymer antioxidants?

Under the effects of shear stress and mechanical loading in an oxygen environment, plastics and elastomers are generally degraded and age rapidly. This is translated by a loss of mechanical properties like strength, stiffness or flexibility and a discoloration, yellowing or loss of gloss of the plastic.

Polymer antioxidants are used to combat this degradation and extend plastics' lifetime. Antioxidants protect the polymer from heat and oxygen ageing.

Antioxidants are added prior to the resin processing. This is why polymer processors, compounders and OEMs need performing and cost-effective solutions which will optimize their business profitability while protecting the plastic all along its lifetime. Converters are looking for antioxidants solutions that will ease and accelerate their production whereas OEM's are paying attention to the polymer quality, aesthetic, durability and regulation compliancy.

How to choose effective polymer antioxidants?

As just said, polymer producers, compounders, converters and OEMs need cost-effective polymer stabilizers, easy to handle, with excellent processing efficiency and, last but not least, compliant with regulatory, safety and environmental requirements. And this is just the tip of the requirement iceberg.

To help you find your path through this additive jungle, Addivant has developed antioxidants allowing you to adapt them to your individual and market challenges in accordance with your production environment. Our objective? Help you grow your business profitability with performing and innovative antioxidants.

Case Studies from Antioxidants

The ultra-low emissive antioxidant for automotive PU foam producers

Addivant™ has designed the NAUGARD® FOAMPLUS LE series to answer the latest and most stringent requirements of the automotive industry and ultimately, the consumers.
NAUGARD® FOAMPLUS LE are new ultra-low emissive antioxidant solutions for flexible polyurethane foams used in automotive applications.

They are drop-in replacements for the existing industry benchmarks and fully meet the stringent VOC and FOG emissions specifications (such as VDA 278) as set by the automotive industry. They also provide excellent protection against degradation (scorch protection and thermal stability) and much more!

Extend polyurethane foams’ lifetime whilst meeting new VOC/FOG requirements in the automotive industry

You are probably struggling to improve automotive polyurethane foams’ durability and, at the same time, to limit the emission levels in order to meet new indoor air quality regulations (for VOC and FOG emissions). Of course, while preserving the polymer’s performance. 

Addivant has developed NAUGARD® PS 3015, a high-performance polyurethane foam stabilisation solution

Unlike the well-known industry benchmark used in polyol/polyurethane applications, NAUGARD® PS 3015 antioxidant enables the production of polyurethane foams meeting stringent new VOC/FOG standards in the automotive industry. In addition, with this new antioxidant solution, there is no compromise on the foams’ performance (scorch reduction, gas fading performance, thermal stability).

How to generate extra revenues by reducing your PE films production downtimes

Powder PE antioxidant, or polymer stabilizers, are blooming on films' surface during the extrusion. This phenomenon generates an accumulation of powder within the extrusion line that needs to be removed. As a consequence, your production line has to be stopped for several minutes and several time a day, which is terrible for your business profitability.

A next generation liquid PE antioxidant has been developed to overcome the drawbacks of powder additives. Download the case study to see why.
