Function of plastic dowel
The main function of rail plastic dowels are to insulate the fastener parts from the ties. Rail plastic dowels are used to guarantee the good connection and linkage of the rail fastening system with the concrete sleeper, with screw spikes or bolts. These plastic dowels of the railway sleeper can also be responsible for the electrical insulation.
Material of plastic dowel
Rail plastic dowels are usually made of HDPE or PA6. The high portion of durable plastics ensures corrosion protection. Sdu Plastic dowel 25mmx165mm and Sdu plastic dowel 25mmx140mm short are most favorite.
Package of plastic dowel
Normally, the package of the plastic dowels are 25kg Per Woven Bag in Gap Wooden Cases.
