TECHNICAL WHITEPAPER Thermal Degradation of Plastics

The Results of Thermal Degradation The chemical reactions involved in thermal degradation lead to physical and optical property changes relative to the initially specified properties. Thermal degradation generally involves changes to the molecular weight (and molecular weight distribution) of the polymer and typical property changes include:

Diet Coke and Mentos

Table Salt Rock Salt Sand Cake Mates Discrepancies exist between the amount of mass lost and distance traveled. Notable samples: Lifesavers, Molecular Sieve Pump Beads, Dawn. These can be explained by the rate of reaction. Reactions that take longer to occur lose lots of mass but the spray doesn’t travel very far. Think Mt. St. Helens vs ...

TECHNICAL WHITEPAPER Low Temperature Properties of Polymers Introduction Most plastics at room temperature show their familiar properties of flexibility (a low Young’s modulus) and high resistance to cracking but when the temperature decreases this can change rapidly and many common plastics become brittle with low failure stresses.

TECHNICAL WHITEPAPER Thermal Degradation of Plastics

The termination of thermal degradation is achieved by ‘mopping up’ the free radicals to create inert products. This can occur naturally by combining free radicals or it can be assisted by using stabilizers in the plastic. A general mechanism for thermal degradation is shown below:
