Why use antioxidants ?

Plastic has become an essential material in virtually every aspect of modern day life. Recent advances in plastic manufacturing and processing have led to ever more applications in which plastics replace other materials such as glass, metal, paper and wood.

Plastic generally ages rapidly under the effects of light, oxygen and heat, leading to:

    Loss of strength, stiffness of flexibility
    Discoloration
    Scratching and loss of gloss
Antioxidants, Light Stabilizers and Fluorescent Whitening Agents can all help to combat these effects.

This Antioxidants Center is designed to help you learn more about the degradation of plastic due do oxygen and heat - and how to combat it by using antioxidants. Just click on any of the topics in the left column to start.
