Refers to do not contain halogen low smoke zero halogen cable (F, Cl, Br, I, At), do not contain lead, cadmium, chromium, mercury and other environmental material made of rubber burning will not emit toxic fumes (such as: halogenated hydrogen, carbon monoxide, carbon dioxide, etc.) of the environmental protection cable.

Low of halogen pointer is: all the value of the halogen ≦ 50 PPM (PREN 14582) according to regulations

Low combustion to produce hydrogen halide gas content < 100 parts per million (according to the regulations EN5067-2-1)

Low combustion halolide gases produced by the soluble in water after PH ≧ 4.3 (weak acid) (EN - 50267-2-2) according to regulations

Low product after burning in airtight container through a beam of light the light transmittance ≧ 60% (according to regulations, EN - 50268-2)

Low Pb < 90 PPM, +, Hg, Cd, Cr6, PBBs, PBDEs are less than 5 PPM

Low smoke zero halogen wire and features:

(1) the tensile strength is larger than general PVC wire, PVC wire tensile strength commonly greater than 1.05 Kgf/was, and low smoke zero halogen wire and tensile strength is greater than 1.2 Kgf/was;

(2) with good weatherability (- 30 ℃ ~ 105 ℃);

(3) have good softness (hardness of 80-90);

(4) has not moved, because the product need not add plasticizer in the formula, so there won't be moving morphic);

(5) does not produce toxic smoke during burning, can produce a small amount of white smoke);

(6) have high volume resistivity: PVC wire is commonly 1012 ~ 1015 Ω/cm3, low smoke zero halogen wire is greater than 1016 Ω/cm3;

(7) has good resistance to high pressure characteristics: generally resistant to 10 kv, PVC wire and low smoke zero halogen wire up to more than 15 kv;

(8) has good elasticity and stickiness.

3. Low smoke zero halogen wire adding material formula:

(1) selection of linear elasticity of PE and PE as main resin, flame retardant material which contains three kinds of water of crystallization of metal oxides: respectively above 200 ℃, 300 ℃, 300 ℃ water of crystallization.
