Silica gel wires have good acid resistance, alkali resistance, antifungal properties, excellent high and low temperature resistance, excellent electrical properties, excellent chemical stability, long service life, humidity and high temperature resistance and a variety of grease. At the same time, the cable has good flexibility, and has the advantages of waterproof and pressure resistance. The wire is soft and easy to install.
The main chain of silicone rubber is composed of alternating silicon atoms and oxygen atoms. Ordinary silicone rubber is mainly composed of silicon chain bonds containing methyl and a small amount of vinyl. The introduction of Ben group can improve the high temperature and low temperature resistance of silicone rubber. After vulcanization, the properties of silicone rubber are greatly improved.
The heat resistance of silicone rubber materials is closely related to factors such as type, vinyl content (crosslinking density), type and quantity of heat-resistant additives and fillers. The pH value and water content of rubber compounds are also closely related. In the selection of raw rubber polymerization catalyst, the neutralization of residual catalyst after reaction, the selection of silica filler and structure control agent are also important factors affecting the heat resistance of silicone rubber.
For the heat-resistant silicone rubber materials, the increase of hardness will be slower at 250 ℃, and the reduction rate of factors such as tensile strength and elongation at break will also decrease accordingly.
Silicone wire and cable of wire manufacturer is suitable for high temperature range below 600v-30kv. Silicone wire has good high temperature and low temperature resistance, flame retardant, radiation resistance, aging resistance, ozone resistance and water resistance.
Silicone wires produced by wire manufacturers are widely used in lighting, overweight and transportation, machinery, electrical engineering, medical and health, metallurgy, aerospace, new energy, lithium battery, power generation system and other high-temperature industries, as transmission lines of electrical equipment, control and monitoring lines, power connection lines and various control signals, mobile power equipment transmission, etc.
