hermoplastics can be subject to degradation if environmental factors are not taken into account.
Environmental conditions that could be damaging to plastics include exposure to UV, moisture, chemicals, temperature and oxidation. Not all grades of thermoplastics are suitable for outdoor applications. Materials that are not UV stable will change both in appearance and molecular structure when exposed to UV, and over time can become brittle, crack, change colour, warp etc.
Careful consideration should be taken to ensure correct material selection for not only the application but also the environment in which the material is expected to perform.
How long will the material / part be expected to last?
To what extend or time period will the material / part exposed to UV?
(For example, direct UV early morning/late afternoon or longer periods of exposure during the high risk UV times of the day.) What other environmental factors impact on the application?
Exposure to other harsh environmental factors, (e.g. water, temperature extremes, chemicals etc.) can impact on overall material performance and contribute to degradation.
This table is a quick guide to assist with product suitability under normal working conditions with exposure to direct sunlight. If you have any questions about environmental effects on thermoplastics, please contact your nearest Dotmar office for assistance.
(Standard grades of thermoplastics can be modified with UV stabilizers to increase UV resistant properties.)
