Gray PVC-U stick Welding Wire Transparent Clear (Clear)
Length of 1 meter in diameter 3 mm and 4 mm
PVC-U welding wire, for PVC-U plastic welding in the manufacture of chemical tub construction, construction for machinery or chemical equipment parts / chemical laboratories etc.
Plastic welding wire generally has a circular cross section, or blunt / triangular triangle (almost oval), used to unite two similar pieces of plastic.
An important aspect of plastic welding wire is the presence or absence of material porosity that can be seen from the cross section (cross section cut).
Porosity causes air bubbles to be trapped (known as voids) in welding wires, this will reduce the welding quality.
The porosity of welding wire material may occur in the extrusion process, because raw materials used are of low quality (regrind) or added by other materials to give volume impact, so that production costs can be lowered, but consequently the quality of welding wire becomes unreliable.
In this case the perfect mixing and binding process between the welding wire and the plastic sheet that you want to put together becomes difficult / failed, or if forced it will cause the risk of leakage or cracks in the future.
