Collection Risks

Rigid PVC boards often contain volatile heat stabilizers, and other additives that can pose risks to collection materials. According to research published in August, 2020, Komacel White Gloss Rigid boards do not contain harmful heat stabilizers that are present in several other PVC boards. [1] It is important to keep in mind that not all PVC products have the same properties and therefore they should not be used interchangeably.

Komacel has routinely passed Oddy tests (see below), but it is possible that low levels of hydrochloric acid will be released during the slow degradation of PVC products. Komacel should be safe to use in most situations, especially for short term display. As an added precaution, avoid placing collection materials in direct contact with Komacel without a barrier. [2]

Environmental Risks

Although the company reports that this product is 100% recyclable this is probably pre-consumer at the manufacturing plant. In practice, there is little to no reported success in finding someone to recycle PVC.
