03/02/2020The opacification occurs when inorganic-based deposits accumulate on the surface of the IOL and are prevalent in hydrophilic materials. Here, the surface of medical-grade PMMA has been fluorinated by sulphur hexafluoride (SF6) plasma treatment to increase surface hydrophobicity thus improving the material lifetime in optical applications.

Get Pricebest sf6 mix emissions in Estonia12/11/2021A recent study suggests that the UK's use of SF6 has risen in recent years, and leakage levels are over 1%. It is estimated that, by 2100, appropriate controls could limit the contribution of SF6 to global warming to 0.2%. In the UK, the gas already contributes this much to its annual global warming potential.

Get Price16/10/2019The utilities industry represents 80% of the SF6 global market, so it is logical that they lead the charge for reducing the use of SF6 by adopting more environmentally-friendly products, like SF6-free switchgear. New medium voltage switchgear technology that uses vacuum interruption and air insulation allows us to avoid SF6. And while air-insulated switchgear for MV applications has long had a reputation of being too large compared to gas technology, this is no longer the case.
