Frequently Asked Questions

Are AURA® infusion technology samples available for lab testing?
A limited number of Makrolon® polycarbonate color chips, colored through AURA® infusion technology are available for examination. However, we suggest that customers provide us with their own parts to be infused. In this way, the customer can determine whether the technology will yield acceptable aesthetics in their own parts.

Is there any loss in physical properties when using AURA® infusion technology?
No. Testing by Bayer so far has indicated no reduction in physical properties.

Will the color rub off the part?
No, the color penetrates into the part, which eliminates potential rub-off.

Do you have any particulation or abrasion studies/results to share?
Abrasion resistance is not changed through the use of AURA® infusion technology. If the polymer has poor abrasion resistance before infusion, then it will have poor abrasion resistance after infusion.

Does the user have to consider stress lines in parts to be treated with AURA® infusion technology?
Yes. AURA® infusion technology is a surface-coloring technique. If the surface area is stressed, the stress lines will become visible.

What happens if the part to be treated by the AURA® infusion technology process is textured?
Textured parts are colored and retain their original texture.

Can AURA® infusion technology be used on glass-filled products?
Yes. However, if the surface is glass-rich, the process will not tint or hide the glass fibers, which can result in undesirable aesthetics.

What about recycling of parts colored through AURA® infusion technology?
Samples colored with AURA® infusion technology can be recycled in the same manner that parts produced from virgin materials in a similar color are recycled, i.e., parts colored with AURA® infusion technology require no separation or special handling.

Is regrind possible with parts to be colored with AURA® infusion technology?
Experiments we have conducted with regrind indicate that regrind is possible and does not present a problem when used in recommended amounts.
