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. Exposure to sunlight and some artificial lights can have adverse effects on the useful life of plastic products. UV radiation can break down the chemical bonds in a polymer. This process is called photodegradation and ultimately causes cracking, chalking, color changes and the loss of physical properties. Plastic generally ages rapidly under the effects of light, oxygen and heat, leading to:
- loss of strength, stiffness of flexibility
- scratching and loss of gloss
- They do not absorb UV radiation, but act to inhibit degradation of the polymer
- Increase Shelf life of the product.
