What are the characteristics of low smoke halogen free flame retardant wire? We don’t know anything about low-smoke halogen-free flame retardant wires. Many people only know about wires, but we still know very little about some wires for different purposes. Therefore, if we want to know about low-smoke halogen-free flame retardant wires What are the characteristics and identification methods of low-smoke halogen-free flame retardant wires? The specific knowledge answers are as follows:
What are the characteristics of low smoke halogen free flame retardant wire?
The purpose of each wire is different, that is because it has the characteristics that other wires do not have, so before we buy low-smoke, halogen-free and flame-retardant wires, let’s first understand what are the characteristics of low-smoke, halogen-free and flame-retardant wires.
1. The characteristics of low-smoke halogen-free flame-retardant wires–the tensile strength is greater than that of ordinary PVC wires: the tensile strength of general PVC wires is greater than 1.05Kgf/mm2, while the tensile strength of low-smoke halogen-free wires is greater than 1.2Kgf/mm2;
2. The characteristics of low-smoke halogen-free flame retardant wire–good weather resistance (-30℃~105℃); good softness (hardness: 80-90);
3. The characteristics of low-smoke halogen-free flame retardant wire – non-migration (because no plasticizer is added in this product formula, so there will be no migration); no toxic black smoke will be produced when burning (a small amount of white will be produced) Smoke); with high volume resistivity: PVC wires are generally 1012~1015Ω/cm3, and low-smoke halogen-free wires are greater than 1016Ω/cm3; (7) It has good high-voltage resistance characteristics: PVC wires are generally resistant to more than 10KV, while low Smoke and halogen-free wires are up to 15KV or more; (8) have good elasticity and viscosity.
