Avient has developed a range of ECCOHTM non-halogen, flame retardant solutions to enable manufacturers to meet the Construction Product Regulations (CPR)

SBS based TPEs will develop a yellow or orange color and a distinctive odor when they have been processed at too high a temperature or held at temperature for too long.

Gravi-Tech™ Density Modified Formulations PROCESSING GUIDE 2 Gravi-Tech GRAVI-TECH™ Density Modified Formulations Gravi-Tech™ polymer-metal composites are high-density materials developed as thermoplastic-based alternatives to lead and other traditional metals.

Email: zach.zander@avient.com Abstract The incursion of microbial growth on polymeric products can deteriorate their performance and lead to the development of undesirable staining and odors. Apart from pathogenic microbes and their apparent impact on human health, bacteria and fungi can also cause staining, unpleasant odors, and deterioration of polymeric product performance over time.[4,5] To reduce the spread of infection through casual contact with con- taminated plastic surfaces, or to extend the useful life of polymer products by preventing the development of said staining or odors, antimicrobial technologies can be employed.[6] For the latter scenario, the use of Environ- mental Protection Agency (EPA)-registered biocides in plastic components is allowable under the “Treated Arti- cles Exemption” set forth by The Federal Insecticide, Fungicide, and Rodenticide Act, which enables polymeric articles to be treated for the purposes of material preser- vation or protection without additional registration requirements.[7] Within the plastics industry, there are certain applica- tions and products where biocides have already found significant usage. All in all, ZPT proved to be a highly effective addi- tive in protecting various TPEs from fungal and bacterial growth, and it is expected that this can extend the useful life of TPE products by preventing microbiological degra- dation and the development of staining, odors, and unsightly growth.[4,5,34] However, it should be noted that leaching of bulk-imbedded biocides from the polymer substrate is required to exert antimicrobial action, and the long-term effectiveness and release of ZPT from these compounds are currently unknown.[16,31,35-37] Future studies are required in order to determine the true dura- bility of the compounds when exposed to the specific envi- ronmental conditions of the end-use target applications (e.g., surfactant washes, humidity cycling, fluid contact, weathering).
