填充聚四氟乙烯制品選用填充聚四氟乙烯樹脂經(jīng)模塑加工制成。懸浮聚合聚四氟乙烯樹脂與各種填充劑混合成填充聚四氟乙烯樹脂。適合與聚四氟乙烯混合的多種填充劑中有玻璃纖維、碳纖維、錫青銅及潤滑劑(如石墨、二硫化鉬)并已廣泛用于規(guī)模生產(chǎn)中。填充聚四氟乙烯與純聚四氟乙烯相比具有較高的壓縮強(qiáng)度,耐磨、導(dǎo)熱好、熱膨脹減少的優(yōu)點(diǎn)。
Filled PTFE article is manufactured by moding method with filled PTFE resin. Filled PTFE resin is manufactured by compounding PTFE granular resin with fillers of many differents kinds. Amongst the many fillers suitable for compouding with PTFE, glass fiber, carbon fiber, Bronze and also lubricating materials like graphite, molybdenum disulphide, have been widely used in large scale production, Broadly speaking PTFE compounds have the following advantage over unfilled.
PTFE. Improved compression strength
Improved thermal conductivity
Dereased thermal espansioin
Improved abrasion resistance
