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.
PTFE is a fluorocarbon solid, as it is a high-molecular-weight compound consisting wholly of carbon and fluorine. PTFE is hydrophobic: neither water nor water-containing substances wet PTFE, as fluorocarbons demonstrate mitigated London dispersion forces due to the high electronegativity of fluorine.t is very non-reactive, partly because of the strength of carbonâfluorine bonds and so it is often used in containers and pipework for reactive and corrosive chemicals. Where used as a lubricant, PTFE reduces friction, wear and energy consumption of machinery.
