Antioxidants

Antioxidants Plastics and elastomers are generally exposed to mechanical loads, heat and friction under the oxygen environment of the air. This oxygen environment causes the material to be rapidly exposed to oxidative effects. Antioxidants are additives used to combat these degradations. Antioxidants protect the appearance, lifetime, heat resistance, hardness and softness of the product - Against degradation in the process - Against colour degradation - Against metal degradation - Against thermal degradation.

The natural structure of polymers (without additives) becomes unstable in the presence of oxygen and starts to degrade. The degradation is the same as the oxidation of raw metal, the colour changes to green brown and flaking begins to form on the surface until the material is unusable. When plastic material degrades, the polymer chains are broken into small pieces or chain separation occurs.

When the physical properties of the polymer deteriorate and the average molecular weight decreases, the melt flow rate increases and the surface becomes dusty. Polymer degradation is a natural phenomenon and cannot be stopped completely. Raw material producers research the colour and physical properties of their raw materials to last longer according to end-user requirements. 

How It Works

Many commercial plastics are produced by chain polymerisation method, polyadition, polycondensation method. When the polymer is exposed to heat, light, air, water, radiation or mechanical loading to the breaking pressure, it causes various changes in the chemical structure and molecular weight of the polymer. These reactions cause modifications in the physical and chemical properties of the polymer.
