PolyOne testing shows that ColorMatrix Amosorb 4020G is one of the most robust oxygen scavengers for PET rigid containers, with negligible effects on efficacy for the rPET grades tested, while other competitive materials lost almost all oxygen scavenging ability with rPET content as low as 20 percent.

In this study, a variety of plastic substrates (30 unique polymer compounds), including poly(acrylonitrile-co-butadiene-co-styrene), poly(butylene terephthalate), poly(etherimide), various thermoplastic elastomers (TPEs), poly(carbonates), and poly(amides), were screened for susceptibility to microbial attack using American Society for Testing and Materials (ASTM) G21 (fungi susceptibility), Japanese Industrial Standard (JIS) Z2801, and modified ASTM E1428-15a (bacterial suscep- tibility) test standards. Among commercially available biocidal additives, ZPT and 2-butyl-1,2-benzisothiazolin-3-one (BBIT) were considered for use to reduce the microbial susceptibility of TPE compounds. All samples were tested in duplicate (n = 2); the bar graph represents the average, and the open circles represent the log10-transformed raw data.

Rigid thermoplastics include both commodity thermoplastics and engineering thermoplastics, such as polypropylene (PP), polystyrene (PS), high impact polystyrene (HIPS), polycarbonate (PC), acrynitrile-butadiene-styrene (ABS), poly(ethylene terephthalate) (PET), poly(methylmethacrylate) (PMMA), styrene acrylonitrile (SAN), poly(phenylene oxide) (PPO), polyamide (PA), PC/ABS blend and PPO/PS blend etc.. Thus, one of the limitations for most of the existing TPE overmolding technology is that one needs to develop and use different TPE materials for different substrates.

It’s in this spirit that we joined legacy PolyOne and Clariant Masterbatch, two complementary businesses, and formed a new one that we’ve named Avient. Through this data, we create safety data sheets, customer certification statements and product safety improvements. Data and information from PolyOne's Performance Products and Solutions segment was not included as it was divested in 2019.
