Meet the cable jackets requirements for very low shrinkage (≤5‰) under high temperature, low temperature, and high and low-temperature cycle conditions. Compared with conventional LSZH materials, the Defender-SCTM series is innovative in that it introduces polar polymers with excellent high and low-temperature resistance, which improves the compatibility of the inorganic flame retardant with the polyolefin composition, while greatly increasing the high and low-temperature resistance of traditional LSZH materials. It makes the material have an obvious improvement in high and low-temperature resistance, mechanical properties, and environmental resistance. It is an ideal jacket material for high-power transmission cables in areas with large ambient temperature changes.
1. Flame retardant:
Fully support optical fiber cable to pass IEC60331-1-2 single vertical burning test;
2. Excellent high and low-temperature resistance shrinkage:
High-temperature shrinkage: 4 hours of treatment at 85°C cycles, if cooled to room temperature, shrinkage ≤ 3‰;
Low-temperature shrinkage: 40 °C for 4 hours, shrinkage at low temperature ≤ 3‰;
High and low-temperature cycle shrinkage: maintained at 85°C for 4 hours, and then reduced to -40°C for 4 hours, after two cycles, the maximum shrinkage at -40°C ≤ 5 ‰.
3. Better processing:
Fully meet the optical cable high-speed extrusion (≥150m/min), the wire diameter is round and stable, less flow, good color stability, higher yield rate. The product batch stability and uniformity are guaranteed.
