M5 White Screw Bolt PTFE Plastic Fastener for Chemical Engineering
screw or bolt is one of plastic fastener that with perfect peformance for industry , and widely used to various fileds , Comparied to other plastic materials , screw bolt with outstanding advantages .
1 . High temperature resistance . can be workable for temperrature from 200 to 260 degress ,
2 . Quite low friction . screw bolt with good lubrication , the friction factor is only 0.4 .
3 . No stickness . not nearly be dissolved to any solvent .
4 . Resistant corrossion
5 . Not easy to be aged ,
6 . Good insulation for electricity .
7 . Low temeprature resistance . screw bolts keep good material performance even 100 degree under zero .
