25. Degradation of Plastic UV Degradation – Unless UV Stabilised – UV Radiation breaks chemical polymer bond – Evaporates – Becomes Thinner – Will Fail

26. Degradation of Plastic UV Degradation Avoidance – Use UV Stabilised Products Added during manufacture – Paint with External UV Protected Acrylic Paints Solar Guard Weathersheild – Avoid Solvent based Paints

27. Degradation of Plastic Constant Exposure to high Temperatures Break Polymer Chains Stabilizers will make plastic resistant to heat
