聚四氟乙烯棒有二種。直徑4-9mm的棒選用分散聚合聚四氟乙烯樹(shù)脂經(jīng)糊膏擠壓加工制成;直徑10-50mm的棒選用懸浮聚四氟乙烯樹(shù)脂徑柱塞擠壓加工制成;直徑50mm以上的棒徑模壓加工制成。
在已知塑料中聚四氟乙烯具有最優(yōu)良的耐化學(xué)腐蝕性能與介電性能,不老化、不粘、在無(wú)負(fù)荷情況下能在-180%°C - +260°C溫度下使用,在已知固體材料中它具有最低摩擦系數(shù)。
There are two kinds of PTFE rods to offer . One is manufactured by paste extruding method in the diameter from 4 to 9mm and the other is made by ramertruding methruding method in the diameter from 10 to 150mm;Rods over diameter 150mm are manufactured by moulding.
PTFE is the most chemical-resistant plastic of all known plastics . It does not age.
PTFE has a wide range of practicalble temperature from -180℃~+250℃ and a wax-like surface to which anything hardly sticks.
PTFE has the lowest coefficient of friction of all know solid materials . It has the best electrical properties of all plastics.
