Gloves
Published in Robert N. Phalen, Howard I. Maibach, Protective Gloves for Occupational Use, 2023
Marie-Noëlle Crépy, Pierre Hoerner
Industrial gloves are made with a wide variety of materials and thicknesses. Various rubber types, such as NR, CR, and NBR, but also Butyl Rubber (IIR), Ethylene-Propylene Diene Monomer (EPDM), Fluoroelastomers (FKM or FPM), Chlorosulfonated Polyethylene (CSM), and Silicone Rubbers (VMQ), are used for the manufacture of industrial gloves. In addition, various other materials which are not conventionally classified as “rubbers,” such as thermoplastics (PVC, TPU, SBC), polyolefins (polyethylene (PE)), polyvinyl alcohol (PVA), polyamides (PA), or leather, can also be used. Each of these materials is selected for its specific features and performance levels, as described in detail in Section 2.

Bisphenol S (4,4′-sulfonyldiphenol, BPS) and bisphenol AF [2,2-bis(4-hydroxyphenyl)perfluoropropane, BPAF] (Figure 1) are structural analogues of bisphenol A [2,2-bis(4-hydroxyphenyl)propane] and are used in a number of applications. BPS is a component of polyether sulfone, a thermoplastic. Polyether sulfone is used in a variety of consumer products and applications, including but not limited to, developer in thermal paper, wash fastening agent in cleaning products, and in microwaveable dishes (Liao et al., 2012c; Rochester and Bolden, 2015). In addition, BPS is used as a chemical intermediate in the preparation of fire retardants, electroplating chemicals and colorant, and as a modifier for leather, fiber, and epoxy curing agents (EPA, 2014). BPAF is used as a crosslinking agent in the synthesis of certain fluoroelastomers (fluorocarbon-based synthetic rubber) and as a monomer in the synthesis of specialty polymers (DuPont, 2006; Halocarbon, 2008; NTP, 2008).
Thermoplastic, rubber-like marine antifouling coatings with micro-structures via mechanical embossing

A thermoplastic elastomer (TPE) was used (polyvinylidenefluoride hexafluoropropylene (P(VDF-HFP), Tecnoflon® N215) which was supplied by Solvay SA and which is referred to by the supplier as a fluoroelastomer copolymer. The TPE was tested via multiple techniques (XRMA, GC-MS, GPC and NMR) for toxic species and these were not found. The lubricant, a perfluorinated polyether (PFPE, Fluorolink E10/6) was also kindly supplied by Solvay SA. A perfluorinated copolymer (fluorinated ethylene propylene copolymer (FEP, TEFLON® FEP 100)) was purchased from Du Pont de Nemours Nederland B.V. The solvent, methyl isobutyl ketone (MIBK) was purchased from Acros Organics and methyl ethyl ketone (MEK) was purchased from Biosolve B.V. An adhesion promoting acrylic basecoat (experimental material XX/04901, a copolymer comprising of methyl methacrylate, lauryl methacrylate and 3-(trimethoxysilyl)propylmethacrylate), a commercial fluoropolymer, a non-biocidal marine fouling release coating (Intersleek® 1100SR), and polydimethylsiloxane (PDMS) were all supplied by Akzo Nobel N.V.
Comparative analysis of two isocyanate-free urethane-based gels for antifouling applications

Vishal Vignesh, Shane Stafslien, Morgan Evans, Kellen Wise, Alec Marmo, Michael Tonks, Anthony Brennan
AAM, HEMA and Irgacure 651 (2,2-dimethoxyacetophenone) were obtained from Sigma Aldrich. HFBMA was obtained from Alfa Aeser. Non-isocyanate urethane crosslinkers NIUDMA (E9/E11/E12) were synthesized by the Brennan Research Group as detailed in the work by Vignesh et al. (2021). Ethanol, nitrogen gas (N2, ultra-high purity), deionized water, heat plate equipped with magnetic stirrer, disposable pipettes, glass slides (Fisher), glass plates, clamps, Fluoroelastomer (Viton®) gasket mold were all obtained from the Brennan Research Group. All other chemicals, unless explicitly mentioned, were utilized as received. Intersleek® 700, 900 and 1100 SR commercial FR coating systems were received from AkzoNobel and prepared as specified by the manufacturer.
