Irradiationcross-linkable PVC compound
I. Type andapplication
Type | Product | Application and Cable Specification |
1151N | 105℃ Irradiation cross-linkable PVC insulating compound | Used for irradiation cross-linkable cables and wires which working temp. of conductor is 105℃ |
1152N | 105℃ Irradiation cross-linkable PVC jacket compound | Used for irradiation cross-linkable cables and wires which working temp. of conductor is 105℃ |
1151N-R | 105℃ Irradiation cross-linkable PVC insulating compound | Used for irradiation cross-linkable cables and wires which working temp. of conductor is 105℃, according with JASO D618-2008 XLPVC standard. |
II. Productdescription
Irradiation cross-linkable PVC compound forcables and wires, based on PVC resin, is made into granula by specialprocessing with adding plasticizer, stabilizing agent, cross-linking agent andother special agents. The products meet various special requirements, such asdifferent hardness, UV stable, environment friend (RoHs, REACH, PAHs,chlorinated alkanes free, phthalatefree, and etc.), sub-shine and fog surface, low temperature resistant, PS/ABStransfer proof, rodent-repellent, termite-repellent, and transparent, and etc.
III. Irradiatingdosage
The normalirradiating dosage of irradiation cross-linkable PVC compound is 6-8 mega-rad.
Note: For the compound would be coloured if the white and nature colourcompound were irradiated directly, the compound need add white colourmasterbatch before processing.
IV. Processing
It is recommended that compound should beprocessed with common extruder having a minimum L/D ratio of 20. Non-specialrequirements of equipment and processing are needed.
The following temperature(℃) profileof extruder is recommended
Zone | Zone 1 | Zone 2 | Zone 3 | Zone 4 | Head | Die |
Temperature ℃ | 140 | 160 | 170 | 175 | 180 | 175 |
V. Storageand transport
Packaging：25kg/bag， PEmembrane inside bag and Kraft outside bag.
Storage and transport: Avoiding in directsunlight and weathering. The storage place should be in clean, cool, dry, andventilated conditions.
