- The effects of exposure to UV radiation results in a color change to the product, slight increase in tensile strength, slight increase in modulus of elasticity, and a slight decrease in impact strength.
- UV degradation occurs only in the plastic material directly exposed to UV radiation and to extremely shallow penetration depths (frequently less the 0.01”).
- UV degradation does not continue when exposure to UV is terminated.
- UV radiation will not penetrate even thin shields such as paint coatings, clothing, or wrapping.
