DescriptionThis Stir Bar made of PTFE which nontoxic and strong corrosion resistance. Its PTFE material deign which you can put it high temperature of -200~ +250 degree. And its weather resistance design that long-term exposure to the atmosphere, the surface and performance of the same.Feature- Color: White.- Material: PTFE.- Size: 31.5x0.8x1cm.- Appearance of pure white.- Low-temperature resistance: a good mechanical toughness, even if the temperature dropped to -196 degree, 5% can also maintain the application rate.- Corrosion resistance: For most of the chemicals and solvents, showing inertia, the ability of strong acid and alkali, aqua regia and a variety of organic solvents.- Non-adhesion: with a solid material in the smallest surface tension, does not adhere to any substance;- High lubrication: the friction coefficient of the solid material (0.04) at the end.- Weather resistance: long-term exposure to the atmosphere, the surface and performance of the same,- Anti-pollution: low blank value of metal elements, lead content of less than 10-11 g / ml.- Non-toxic: a physiological inertia, as artificial blood vessels and organs long-term implantation of the body without adverse reactions.- High temperature: the use of temperature -200 ~ +250 degree; hot plate can be short-term resistance to 300 degree, open fire in the asbestos to be used.
