Don't automatically jump to HF QC issues. Many rubber blends react with other plastics, some just don't have a long life regardless.
I remember growing up many of my fishing lures, especially the "live rubber" skirts would melt into the plastic on my tacklebox in no time flat.
I've used those gloves, and the Atlas, and a few others. The rubber on all of them do that, some faster than others, but I've never gotten more than 2 years out of a pair with most pair only lasting a few months to a year. Keel in mind, my use was solely for shoveling snow on my plow route and at home. I much prefer the thinner purple rubber nitrile/neoprene ones for anything besides shoveling that I might want that kind of glove for...5 years and counting on the two pair I have of those.
