Ceramic silicone rubber is a kind of high polymer fire-resistant material which has been popular in recent years

　　1、 Excellent electrical insulation: it can achieve the electrical properties of XLPE and EPDM: volume resistivity of 2 × 1015 Ω· cm, breakdown strength of 22-25kv / mm, dielectric loss tangent of 10-2, dielectric constant of 2-3.5, which can be used for insulation;

　　2、 High and low temperature resistance: the long-term working temperature is - 70 ~ 200 ℃, and the service life can reach 5-50 years according to different environmental conditions;

　　3、 Ozone and ultraviolet aging resistance: no need to add antioxidants and antioxidants, the service life at room temperature can reach more than 30-50 years;

　　4、 Special surface properties: low moisture absorption, good mildew resistance, non stick to many materials;

　　5、 Environment friendly: Halogen-free, heavy metal free, non-toxic, tasteless, no impact on human body and environment;

　　6、 Good chemical corrosion resistance, water and oil resistance;

　　7、 Excellent hydrophobicity, pollution flashover resistance and creepage resistance;

　　8、 Good processability: easy mixing, molding, calendering, extrusion, molding and other processing, good fluidity of rubber compound;

　　9、 At present, the toxicity of smoke is za1 grade in polymer materials, especially in cable materials. That is to say, the mice inhaled the burning smoke for 30 minutes, and there was no change within three days;

　　10、 The thermal conductivity is 0.0033w/mk, especially the honeycomb after ablation, which has better fire resistance and heat insulation;

　　11、 Good flame retardancy: the flame retardancy can reach FV-0 level, the oxygen index is more than 32, and the high can reach more than 38. After ignition, it does not delay combustion, and the combustion with conductor is basically not ignited;

　　12、 The higher the temperature is, the longer the ablation time is, the harder the ceramic armor is. It is better than mica tape, which becomes hard and brittle after combustion, and is easy to fall off;

　　13、 The fire resistance grade of fire-resistant wire and cable made of ceramic silicone rubber can reach the standard of gb12666.6, that is, it can burn in 950 ~ 1000 ℃ flame for 90 min, 3A fuse will not blow; it can also reach the C, W, Z grade of bs6387, that is, C - burn in 950 ℃ flame for 3 h, W - spray water, Z - vibration;

　　14、 Low density (1.42), low price (40000 yuan / ton), high cost performance;

　　15、 Based on the above characteristics, it can completely replace mica tape for medium, low and high voltage fire resistant wires and cables.

　　Ceramic silicone rubber is different from other rubber, plastics and other big characteristics - in the case of fire, high temperature, can be fired into a hard ceramic, this is the ceramic silicone rubber is different from all the current polymer materials "sex" characteristics, but also its key characteristics.
