Resistance to strong acids, alkalis and organic solvents is a major feature of PTFE Teflon hoses, which can transport almost all chemical fluid media; high temperature resistance - long-term use temperature 200-260 degrees, low temperature resistance - still soft at -100 degrees; corrosion resistance - resistant to aqua regia and all organic solvents, weather resistance - the best aging life among plastics; high lubricity - has the smallest friction coefficient among plastics (0.04), non-stickiness - has the smallest surface tension among solid materials and does not adhere to any substance.
