This stops polymer chains from breaking down and prevents uv damage.
Uv absorbers keep your materials strong and looking good.
Tip: If you add uv absorbers like KST-UV312, your products last longer and keep their color and strength.
Uv absorbers do more than block rays. They turn uv energy into something safe. When a uv absorber molecule takes in a photon, it starts to move and shake. This movement turns the energy into heat. The heat spreads out safely in the material. The process happens very fast, so uv energy cannot hurt the product.
Here are the main steps in this table:
| Mechanism | Description |
|---|---|
| UV Absorption | Uv absorbers catch harmful uv rays before they reach the material. |
| Energy Conversion | The absorbed uv energy turns into heat, not damage. |
| Photosensitization Prevention | The energy leaves the molecule in a way that does not start new reactions. |
