production equipment | includes vacuum vulcanizing machines, large-scale flat vacuum
vulcanizing machines, rubber machines, CNC machine tools,
temperature-controlled ovens and detectors. |
Material ptfe/teflon | Display almost universal chemical resistance, an extremely low
friction value which results in very good sliding characteristic,
no stick-slip effect, particular rigidity and almost unlimited
ozone, weathering and ageing resistance, PTFE is impervious to
almost all known hydraulic media, lubricants, chemicals and
solvents.PTFE is non-flammable and so does not constitute and
additional hazard in case of fire. Pure PTFE is not totally without
disadvantages as it has a tendency to cold flow or crawl under
pressure load. These weaknesses are counteracted by the use of seal
compounds mixed with fillers. |
