聚四氟攪拌棒的材料為聚四氟乙烯。其耐腐蝕、耐強酸、強堿、王水和各種有機溶劑。除熔融金屬鈉和液氟外，能耐其它一切化學藥品。在王水中煮沸也不起變化。耐極限溫度：能在+260℃至-180℃的溫度下長期工作。不粘附任何物質，無毒害。具有生理惰性，可植入人體內，對人體無害。不易破損，極大地提高使用壽命，長期使用比玻璃制品更經濟。

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.
