Halogen Free flame retardant:
1. Applications and cable specifications:
General type. Used as cross-likable low smoke halogen free insulation and jacket for electronic wires, cotton coverd wire for construction. Work temperature: -40 to 125 degree C .
2. Description:
Silane crosslinkable low smoke halogen free POE compound, based on POE resin, is produced and pelletized by special technology, adding flame retardant, initiator, crosslinking agent and other special additives. This compound is composed of A materials and B materials, when it is used, please mix the A and B in the proportion of 97:3. This compound has advantage of excellent properties, processing easily, and excellent physical properties, meeting JB/T 10436-2004 standard.
3. Processing:
Equipment: it is recommended that this compound should be processed by professional screw for halogen free compound, with compression ratio of 1.2 to 1.5 (L:D should be 25 to 18). If you use PVC extruder, the speed should be lower and focus on cooling.
The following temperature(degree C) profile of extruder is recommended (temperature here is only for reference, and it will be different according to different extruder and temperature controlling equipment):
Zone | Zone 1 | Zone 2 | Zone 3 | Zone 4 | Head | Die |
Temperature | 110 | 140 | 160 | 160 | 165 | 170 |
Method of application:
(1) When you use this product, please mix A and B before put into the hopper. If you need color, the cable factory can use the polyvinylene masterbatch. The material should be used up after it opened in 8 hours and the rest can be resealed and usable within 24 hours.
(2) The extruder should be cleaned with PVC material after stopping, (It is preferable if you can take apart the screws to clean.)
(3) The silane crosslinkable LSZH compound should not be stayed in the extruder for a long time .If it stayed for long time, it will pre-crosslink after open the machine, which will make lumps in the surface of cable. It need to be discharged all the pre cross-linker, and then produce the cable properly.
(4) To ensure the safety and fully of the cross-linking, when immersed the compound into the hot water or steam, please calculate the cross-linking time based on the terms of more than 85℃, 8h/mm thickness cross-linking speed.
(5) At room temperature, the degree of crosslinking can also meet requirements after 7-10 days. The specific time can be different according to the temperature and humidity.
Note:
(1) Transportation: avoid direct sunlight and weathering and machine damage
(2) Convey: discharge softly, put off softly, avoid from the bursting by the stressed with the aluminum-plastic Bag.
(3) Storage: it can not be landing stack. It should be put on the pallet in the clean dry storage.
(4) Keep dry: When the material used, it must not be contained the outer water. Otherwise, it will seriously pre-crosslink.
(5) Quality guarantee period: 6 months after manufacturing.
4. Storage and transport:
Packaging:25kg/bag, Aluminum foil and PE film bag inside, and Kraft bag outside.
Storage and transport: Avoiding in direct sunlight and weathering. The storage should be clean, cool, dry, and ventilated.
