Causes of Kyphosis. Kyphosis can occur in people of all ages, but is most common in older patients who suffer from osteoporosis. The condition results from compression of the vertebrae in the spine. Another form of Kyphosis, called postural kyphosis occurs when a person exhibits excessive slouching habits.
Polytetrafluoroethylene (PTFE) is an engineered fluoropolymer. Oustanding resistance to chemicals is one of its primary attributes. A broad temperature range of -100Â°F to 500Â°F (-73Â°C to 260Â°C) make this hose material suitable for the majority of fluid and ambient temperature conditions found in industry.
it has a unique structure In chemistry, polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene which finds numerous applications. PTFE is most well known by the DuPont brand name Teflon. PTFE is a fluorocarbon solid, as it is a high molecular weight compound consisting wholly of carbon and fluorine. Neither water and water-containing substances nor oil and oil-containing substances are wet by PTFE, as fluorocarbons demonstrate mitigated London dispersion forces due to the high electronegativity of fluorine.
