Processing Parameters:
JK-ZH-140 range of compounds are designed to perform on extruder with Low
compression ratio screws meant for PE extrusion. However it can also be used
on PVC extruder with limitation on output. The recommended temperature for
extruding JK-ZH-140 compound is in the range of 115°C to 145°C for barrel and
150°C for cross head and die. Extra caution must be exerted to see that the
processing temperature does not exceed 175°C which will result in
degradation of the material. Pre-drying of the compound is recommended at
70°C for 2 hours to obtain smooth processing of the cable and attaining good
surface finish on the cable.
Colorability
JK-ZH-140 is a Colorable Compound with PE/EVA base master batch.
Packaging & Storage:
JK-ZH-140 compounds are free flowing pallets and are packed in securely
sealed laminated PP bags with liner to protect against moisture.
The standard packing is 25 kg per bag.
It is recommended to store the material away from direct sunlight and cool
and dry place.
Shelf Life:
Shelf Life of the compound is 12 months from the date of manufacture.
Product alteration may occur due to extended period of storage
