The Universal Selection Source: Polymer Additives

Addivant
Polymer stabilizers are necessary to avoid polymer ageing. Heat, UV light radiation, shear stress, oxygen, mechanical loading are responsible for polymer degradation, loss of mechanical and aesthetical properties. Antioxidants and UV light stabilizers 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 & light stabilizers?

What is the purpose of polymer antioxidants and UV light stabilizers?

Under the effects of UV light, heat, 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 and UV light stabilizers are used to combat this degradation and extend plastics' lifetime. Antioxidants protect the polymer from heat and oxygen ageing whereas light stabilizers are preserving polymers from UV radiations.

Both additives 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 and light stabilizers 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 and light stabilizers?

As just said, polymer producers, compounders, converters and OEMs need cost-effective heat and light 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 UV light and heat stabilizers 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 Polymer Stabilizers

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.

How to increase the amount of re-grind material when producing PE films

Polyethylene film producers are regularly using re-grind materials to recycle their damaged films and avoid wasting too much resin. Traditional powder antioxidants offer limited use of re-grind material and a limited number of extrusion passes (1 up to 3 passes maximum). Next generation PE antioxidants allow much more extrusion pass and a higher amount of re-grind material thanks to their better heat protection.

How to increase your PE film production output without generating additional yellowing/optical defects

PE films producers are often running their extrusion line at maximum speed and are therefore limited to boost their production capacity. However, the choice of a more performing processing stabilizer, also known as polymer antioxidant, can help you to accelerate your extrusion speed. Download the case study to see why.
