Description
Grade 4251/4251B is silane XLPE compound with monosil method (one step) and is specially used for 1KV and below cable & wire. It has outstanding performance in processing temperature, easy processing characteristics and excellent product properties.
Standard
After crosslinked in the tepid water, the cable made from our product grade 4251/4251B can comply with the standard of IEC60502-2004,GB/T12706-2002.

Typical values were tested on the 1mm sample strip by squeezing film extrusion and be boiled in hot water at 90℃ for four hours.
*Especially, these typical values were tested by press moulding sample under the condition of 180±2 ℃, 15min, and pressure over 15Mpa, then boiled in 90℃water for four hours.
Recommended Processing Technique
1. Extrusion Equipment
Most extruders for PVC and PE suit for 4251/4251B
The recommended equipment and processing technique is as following.
Ratio of length and diameter 18—25:1
Diameter 45—120mm
Ratio of compressing 1.5—3.5
Ratio of elongation 1:1.0—1:1.5
Filtering mesh 40/60/40
2. Extruder processing temperature and other related settings
Temperature Setting: Specific processing temperature should be based on different equipment and pressing conditions, reference settings are as following:
Feeding Section(℃) | Compression Section(℃) | Measurement Section (℃) | Die head and Mould (℃) |
150~165 | 165~180 | 180~200 | 200~210 |
Die head setting: Tubing extrusion style is recommended
3. Crosslink
After extrusion and cooling, the cable can be crosslinked by immersed in hot water (90℃) or exposed in low pressure vapour. The time required for crosslink is based on the thickness of the insulation and the coil size, the thicker the insulation andthe greater the coil size, the longer the crosslink time required. The crosslink time can be calculated according to the equation of 4hr/mm for 90℃.

Note:
1. The independent small package in product grade 4215B is black masterbatch, it must be mixed evenly with silane XLPE compound of monosil method firstly before use.
2. If the cables made from our product grade 4251/4251B fail in heat elongation test, it would be related to the processing techniques. Please contact us any time if you find this problem.- Q:What are the varieties of wire and cable (detailed point)
