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.
RE: PTFE Vs. TFE. PTFE is the chemical description for polytetrafluoroethylene, or better known as DuPont's Teflon. Many other suppliers also manufacture PTFE grannular and free flow resins. TFE is the chemical name for tetrafluoroethylene, which is a colorless and taseless gas, extremely toxic and ultimately deadly. Don't confuse the two, although the plastics industry has misused these terms over the years interchangably.
