The meaning of PFAS is synthetic chemicals that contain fluorinated carbon atoms, are used in consumer and industrial products for their desirable properties (such as water, stain, and fire resistance), are highly resistant to breakdown, and accumulate i
“Forever chemicals” have commonly been used in outdoor and activewear to provide better water resistance and durability. But now some states and consumers are demanding changes.
The prevalence of PFAS compounds in environmental samples require an end to end workflow that is highly sensitive to quantify at parts per quadrillion levels (ppq), free from the spoils of contamination throughout the method, produces consistent, precise, and reliable results from injection to ...
A complete transition to fluorine-free foams (F3) has therefore been requested by some clients to reduce ongoing or future risks of contamination. Foam transition requires a thorough cleanout of the previous foam material to avoid cross-contamination with newly introduced F3 material. A traditional ...
From our vantage point as we have helped several brands behind the scenes become fluorine-free, the vast majority of the problems we have encountered over the past three years are mostly related to PTFE. PTFE is also known to be very common in manufacturing in general, meaning it’s safe ...
HyperDRY ECO— works the same way as traditional DWR chemicals by building carbon-hydrogen chains on the down cluster to decrease the surface tension, which ultimately causes water to bead and roll off. The difference is that the HyperDRY compound is completely PFC Free, meaning it is ...
The V0 rating is the highest level of flame-retardant performance in the industry, meaning the material will extinguish within 10 seconds when a flame is applied vertically. LG Chem said it is the first company to certify a V0 level or higher flame-retardant performance with...
(GenX). PFBS, PFNA, PFHxS, and Gen X will also be regulated together as a group using a unitless hazard index. These values are grounded in the health-based MCLGs (of 0—meaning that they conclude that there is no safe level of these compounds in drinking water) but also incorporate ...
Accidental Origins Like penicillin or the mess-free adhesive that makes Post-it notes stick, the first PFAS were discovered by chance. It was 1938 when a failed experiment led DuPont chemist Roy J. Plunkett to create PTFE resin, a waxy, slippery, white substance. It was heat-resistant with...
” Carpenter and O’Bannon set out to make the “ultimate riff on Stanley Kubrick’s 2001: A Space Odyssey,” says Griffiths. While Kubrick’s 1968 film, explains Muir, was one “in which viewers sought meaning in the stars about the nature of humanity, there is no meaning to ...
