聚四氟搅拌棒的材料为聚四氟乙烯。其耐腐蚀、耐强酸、强碱、王水和各种有机溶剂。除熔融金属钠和液氟外，能耐其它一切化学药品。在王水中煮沸也不起变化。耐极限温度：能在+260℃至-180℃的温度下长期工作。不粘附任何物质，无毒害。具有生理惰性，可植入人体内，对人体无害。不易破损，极大地提高使用寿命，长期使用比玻璃制品更经济。

Materials for teflon ptfe stirbar. Its corrosion resistance, resistant to strong acid, strong alkali, aquaregia, and a variety of organic solvents. In addition to the molten metalliquid and sodium fluoride, can all other chemicals. Boil in aqua regia doesn'tchange. Resistance to extreme temperature: can at + 260 ℃ to 180 ℃ under the temperature ofworking for a long time. Don't adhere to any material, non-toxic. Havingphysical inertia, can be embedded in the body, harmless to the human body. Noteasy to damage, greatly improve the service life, use for a long time moreeconomic than glass products.
