Typical values in the table are measured under the condition that the material is fully crosslinked, and if suficient crosslinking is not achieved, the performance of the material may be different.
Processing:
it is recommended to use a conventional extruder (three-layer co-extrusion, length-diameter ratio of 20:1 to 30:1)for operation, and other equipment needs to be adjusted according to the situation.
