纯
TFE
Virgin TFE
纯
TFE
是一种很好的、多用途、通用的阀座材料。
TFE
具有显著的耐多种化学
腐蚀的性能，
包括有机化学材料，
无机化学材料和多种溶剂，
通常被认为
是化学
惰性物质。
TFE
是一种自润滑
聚合物，摩擦系数很低，这使得
TFE
成为角行程
球阀极好的阀座材料。
Virgin TFE
is a good all-around, general purpose seating
material. TFE has
outstanding
resistance to chemical attack by a broad spectrum
of organic
chemicals, inorganic
chemicals and solvents and is generally considered
chemically inert. TFE is a
selflubricating polymer with a very low
coefficient of
friction, which makes an
excellent seating material for quarter-turn ball
valves.

NIBCO uses
short strand fiberglass as a reinforcement for our
mid-range ball
valve products. Adding
reinforcement increases the pressure containing
capabilities of TFE by reducing its
tendency to cold-flow.
