Sec. 1. (1) The legislature finds that 10 hydrofluorocarbons are air pollutants that pose significant threats 11 to our environment. Although hydrofluorocarbons currently represent a 12 small proportion of the state's greenhouse gas emissions, emissions 13 of hydrofluorocarbons have been rapidly increasing in the United 14 States and worldwide, and they are hundreds to thousands of times 15 more potent than carbon dioxide. In 2019, the legislature took a 16 significant step towards reducing greenhouse gas emissions from 17 hydrofluorocarbons by transitioning to the use of less damaging 18 hydrofluorocarbons or suitable substitutes in certain new foam, 19 aerosol, and refrigerant uses. However, significant sources of 20 hydrofluorocarbon emissions in Washington remain unaddressed by the 21 2019 legislation, including legacy uses of hydrofluorocarbons as a p.

The contribution of fluorinated greenhouse gases to global warming is projected to triple from nearly 2% to around 6% of total greenhouse gas emissions by the year 2050. This is revealed by global projections prepared for the Federal Environment Agency in a scenario where no new measures are taken. The need for action is evident. F-gases are mostly used in similar ways to the CFCs and halons used in the past, which are responsible for the destruction of the ozone layer in the stratosphere.

  • Low-Surface-Energy Fluoromethacrylate Block Copolymers with Patternable Elements
    Chem. Mater. 2000, 12, 33-40 33 Low-Surface-Energy Fluoromethacrylate Block Copolymers with Patternable Elements Shu Yang, Jianguo Wang,† Kenji Ogino,‡ Suresh Valiyaveettil,§ and Christopher K. Ober* Department of Materials Science and Engineering, Cornell University, Bard Hall, Ithaca, New York 14853-1501 Received April 26, 1999. Revised Manuscript Received October 19, 1999 A series of block polymers were synthesized from tetrahydropyranyl methacrylate (THPMA) and several fluorinated methacrylates. By changing both the length of the fluorinated side chain and the nature of its end group, the surface properties of these polymers were greatly influenced. The polymers with perfluoroheptyl groups showed the lowest surface tension, ∼7 mN/m, whereas those with perfluoropropyl groups showed surface tension around 12 mN/m. The surface tension changed dramatically when the perfluorinated side chain with a CF2H end group was capped, increasing to 18 mN/m for three -CF2- units. The relative volume ratios of different block copolymers did not affect the resulting surface energy. After thermal decomposition of labile THP- groups in these polymers, acid and acid anhydride groups were produced. Thermal cross-linking of these groups increased mechanical robustness and led to better surface stability and adhesion of the polymer to the substrate. Because these polymers were designed for their lithographic abilities, some aspects of their photoimaging properties are discussed. Introduction surfactants, or emulsifiers,2 some of which are soluble in supercritical carbon dioxide.3,4 A monolayer of these Precise control of the surface properties of polymeric materials, properly organized, will make a very low- materials by means of self-organization is a major energy surface.

It is made of perfectly safe polyether/ester, a compound of polyester and polyether molecules which makes it absolutely environmentally friendly and kind on the skin and also means it can be recycled like a PET bottle. Other membranes such as Gore-Tex and eVent are made of PTFE (polytetrafluoroethylene) whose manufacture, disposal, heating and incineration may release PFCs (per and polyfluorinated chemicals / fluorine compounds) which are regarded as ecologically problematic. The performance of fluorine-free polyester membranes and PTFE-based membranes are very similar in terms of them being windproof, breathable and waterproof. Water-repellent impregnations / General facts To meet requirements relating to functionality and care, the outer materials used in outdoor clothing generally have a water-repellent treatment (impregnation) on the outside and a membrane on the inside. The Sympatex membrane ensures that functional clothing is waterproof. Water-repellent treatments also ensure that the textile has durable water-repellent properties. A DWR (durable water repellent) treatments is an extremely thin coating of the individual fibres which ensures that water simply forms beads and falls off. This treatment prevents or delays the ingress of water into the outer material. The result of this is that the garment does not absorb water, it does not gain weight, the

  • ESL Fact Sheet
    FACT SHEET HYRODGEN FLUORIDE AND OTHER SOLUBLE INORGANIC FLUORIDES CAS#: 7664-39-3 This fact sheet provides a summary of the Development Support Document (DSD) created by the Toxicology Division (TD) of the Texas Commission on Environmental Quality (TCEQ) for the development of Regulatory Guidelines (ESL and ReVs) for ambient exposure to this chemical. For more detailed information, please see the DSD or contact the TD by phone (1-877-992-8370) or e-mail ([email protected]). What are hydrogen fluoride and inorganic soluble fluorides? Inorganic soluble fluorides (F) exist in the atmosphere as both gas and particulates and are used in the production of aluminum, steel, phosphate fertilizers, phosphoric acid, glass, ceramic, and brick products. Hydrogen fluoride (HF) is widely used in the production of fluorocarbon chemicals. Anhydrous HF is used as a catalyst in the production of most fluorine-containing chemicals; as a fluorinating agent in the production of fluorine and aluminum fluoride; and in refining uranium. It is used in the production of refrigerants, herbicides, pharmaceuticals, high- octane gasoline, aluminum, plastics, electrical components, and fluorescent light bulbs. Aqueous hydrofluoric acid is used in stainless steel pickling, glass etching, metal coatings, exotic metal extraction, and quartz purification. How are HF and soluble F released into ambient air? Naturally-occurring F including HF can be released into the air through volcanic activity, dust from soils, and sea-water droplets, then carried into the atmosphere by winds. However, most of the airborne F is generated through the burning of F-containing fuels and from industrial sources. Major sources of industrial HF and F emissions are aluminum production and phosphate fertilizer plants.

Synthesis of highly fluorinated SCPNs from highly fluorinated uni-block copolymer precursor utilizing ‘pseudo-high dilution continuous addition technique’ was investigated. GPC confirmed selective intramolecular crosslinking and TEM images supported formation of sub-20 nm spherical polymer nanoparticles. Amphiphilic SCPNs prepared via step-wise crosslinking of an amphiphilic di-block copolymer chain were investigated for their morphology using 4 different characterization techniques: TEM, AFM, DLS and DOSY-NMR. TEM and AFM images showed presence of discreet SCPNs as loosely crosslinked coils that flatten out when deposited on the surface forming pancake like morphology with ≈ 20 nm sizes. All the techniques showed presence of bimodal size distribution of these nanoparticles in solution. A smaller sized distribution represented discreet SCPNs whereas larger sized (>40 nm) distribution represented physical aggregates of SCPNs. These aggregates were broken down upon significantly diluting the solution of nanoparticles (≤50 ng/mL).

OCCUPATIONAL EXPOSURE TO DECOMPOSITION PRODUCTS of FLUOROCARBON POLYMERS U.S. DEPARTMENT OF HEALTH, EDUCATION, AND WELFARE Public Health Service Center for Disease Control National Institute for Occupational Safety and Health September 1977 For sale by the Superintendent of Documents, U.S. Government Printing Office, Washington, D.C. 20402 DHEW (NIOSH) Publication No. 77-193 PREFACE The Occupational Safety and Health Act of 1970 emphasizes the need for standards to protect the health and safety of workers exposed to an ever-increasing number of potential hazards at their workplace. The National Institute for Occupational Safety and Health has projected a formal system of research, with priorities determined on the basis of specified indices, to provide relevant data from which valid criteria for effective standards can be derived. Recommended standards for occupational exposure, which are the result of this work, are based on the health effects of exposure. The Secretary of Labor will weigh these recommendations along with other considerations such as feasibility and means of implementation in developing regulatory standards. It is intended to present successive reports as research and epidemiologic studies are completed and as sampling and analytical methods are developed. Criteria and standards will be reviewed periodically to ensure continuing protection of the worker. I am pleased to acknowledge the contributions to this report on the decomposition products of fluorocarbon polymers by members of the NIOSH staff and the valuable constructive comments by the Review Consultants on the Decomposition Products of Fluorocarbon Polymers and by Robert B.
