Odor & VOC reduction Imerys minerals reduce VOC emissions in plastic compounds
Imerys minerals have an odor diluting effect in applications such as automotive parts, building materials, flooring and packaging.
During polymer transformation processes, the heat and shear energy inputs required to melt the polymer cause bond-breakages of the polymer molecules, leading to undesirable reactions. The free radicals generated can attack other polymer molecules or react with oxygen in the air to form low-molecular-weight, oxygen-containing chemicals such as aldehydes and ketones. These chemicals can evaporate into the air as odorous volatiles.
- Demonstrate high absorption power minimizing odor release
- Maintain mechanical properties
- Improve thermal resistance
Imerys minerals are ideal for meeting VDA 270 and VDA 278 automotive standards.
We particularly recommend our:
- New ImerSorb® high-surface-area mineral additive
- Steagreen® surface-treated talc
ImerSorb®, a new mineral additive that reduces odors and VOCs in plastics
We offer a full range of bespoke formulation and technical and process support services to help you match the right mineral grade to your application requirement.
