YUCHENGTECH 20g PTFE Weight PTFE F4 Weight Acid Alkali Resistant PTFE Balancing Weight for Lab Used on a Balance 2 pieces/lot

Introduction PTFE is a polymer of tetrafluoroethylene with excellent chemical stability and corrosion resistance. PTFE main characteristics: 1. Extraordinary chemical resistance, tolerating almost all chemical solvents (strong acid, strong alkali and various organic solvents). 2. The appearance is pure white, clean and sanitary, less pollution. 3. High temperature resistant, use temperature -200～+250℃, short-term endurance of 300℃ on the heating plate. 4. Good low temperature resistance: - 196℃ can be maintained at 5%. 5. It shall be used on the asbestos net without direct contact with naked flame, which is used for sample digestion, boiling, steaming and other treatment. 6. High lubrication: the lowest coefficient of friction in solid materials. 7. Non-adhesion: non-adhesion of any substance; Self - wettability: friction coefficient of solid material is 0.04. 8. Non-toxic: it has physiological inertia and can be implanted into human body; Anti-aging, can be used in the atmosphere for a long time. 9. Anti-pollution: the blank value of metal elements is low, the content of lead is less than 10-11 g/ml, and the content of uranium is less than 10-12 g/ml. parameter Weight: 20g Error: ±0.1g Diameter: 22mm
