Small size PTFE vacuum bellows   Product Description PTFE features of  small size PTFE vacuum bellows   PTFE, PE, rubber characteristics introduction   PTFE is one of the best corrosion resistance materials.          Small size PTFE vacuum bellows features 1.High temperature resistance, working temperature can reach 250 °C.   2.Good low temperature resistance, good mechanical toughness; Even if the temperature dropped to - 196 °C, it can also maintain the elongation of 5%.   3. Corrosion resistance- to most chemicals and solvents, inert, acid alkali, water and a variety of organic solvents.   4. Weather-proof, service life is longest.   5. High lubrication - the lowest friction coefficient in solid materials.   6. Inadhesion - the surface tension of the solid material is is the smallest, don't adhere to any material.   7. Non-toxic, has a physiological inertia, as artificial blood vessels and organs implanted in the body for a long time without adverse reaction.   Usually, PTFE color is white, and PE color is grey.        Packaging & Shipping There are bellows cap to prevent ptfe vacuum bellows damage, and outside package is wooden case.       FAQ 1.Do you supply custom?
