Details:
125 EM Radiation Crosslinking Flame Retardent XLPE Wire&Cable Compounds
1. Introduce
HEGC 1251H is a low-halogen, flame-retardant, radiation crosslinking XLPE, wire&cable insulation compounds. It has been designed for flame retardent appliance material wire, especially UL 3398, 3321, 3289 etc. If need. Standard color concentrates(EVA or PE based)can be used or we can provide directly color compound. The compound has the following features: Good physical properties, Good electrical properties, Highly flame-retardant, Excellent processability.
2. Processing Techniques
It has excellent processability, it'Draw-Down Ratio is greater than 2: 1. Pressure Die, Semi-pressure Die, Tube-on Die can be used. In a generaly way, Pressure Die is recommended. It can be processed with ordinary screw extruder with L/D=18-25\Screw compression ratio≤ 3: 1.
Recommended processing temperature:
150\165\175\175\165\165 Die
The above temperature can be adjusted according to actual situation, but generally not exceed 185.
Recommended radiation dose: 12-16Mrad.
