Long term heat ageing

One of the limiting factors in the application of plastics at high temperatures is their tendency to not only become softer but also to thermally degrade.Thermal degradation of polymers is ‘molecular deterioration as a result of overheating’. At high temperatures the components of the long chain backbone of the polymer can begin to separate (molecular scission) and react with one another to change the properties of the polymer.

Sonali Long term heat ageing masterbatch can be used as stabilising agent to prevent degradation of polymer against long term outdoor and heat exposure.
