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.
Frying pans are often coated with PTFE because of the material's stick-resistant properties. The low frictional properties of PTFE make it ideal for coating ball bearings, gears, and flywheels. PTFE is used to insulate pipes that carry toxic or corrosive materials, such as those found at nuclear power plants.n terms of plastics, friction is usually observed against polished steel. To put the low friction coefficient of PTFE into proper perspective, it is the only known synthetic surface material to which the toe pads of a gecko fail to stick.
