Production Processs
Recommendable temperature of the extruder fuselage: 70ºC-110ºC.
Neck temperature: 100ºC-110ºC
Head temperature: 110ºC-115ºC
Recommendable to use the mesh 20x60 with double-layer filter.
Package Storage
The semi conductive shielding material is installed in the double-layer polyethylene film. After sealed package, it is loaded into the hard corrugated box which is not easy damaged, and the outer membrane is water proof, the net weight of each case is 600kg. It is stored in a clean, dry and ventilated warehouse, with a height of less than two layer. The transport process keeps away from sun, rain and mechanical impact.
