The Stabilizer system has a significant influence on the performance and service life of PVC cables. It enables efficient manufacture of cables and wires, ground cables, installation cables, telecommunication cable and imparts specific attributes to the finished products-including good heat stability and electrical properties, initial color and color stability, suitable for light and heavy calcium black, white wire and cable, excellent thermal stability, suitable for power cable jacket.
Suitable for soft, semi-rigid wire and cable material, environmental protection, non-toxic PVC plastic products, such as wire and cable, rolling film products, SGS inspection in line with the European ROHS environmental standards and other countries around the world a series of environmental standards.It can be used for j-70, h-70,UL60 ~ 105 wire and cable.
With better temperature resistance, suitable for the formulation of heavy calcium carbonate, good initial coloring and stability.
Congo red can be greater more than 80 minutes
Suit for white and black wire & cable
|Calcium carbonate||50 PHR|
|Flame retardant||1.6 PHR|
PVC has been used to produce wire and cable insulation and jackets for more than 50 years. PVC formulations must have matching characteristics, ranging from grounding, telecommunications, installation and heating wires to cables for the electronics and automotive industries. The stabilizer system has a significant impact on the performance and service life of PVC cables. It can effectively manufacture cables and wires, and give the finished product specific properties-including good thermal stability and electrical properties, initial color and color stability, good mechanical properties, stabilizer dispersion
① Experimental conditions
In an electric aging box with natural ventilation, the temperature was 135±2℃, and after being placed for 336 hours, the change rate of tensile strength and elongation at break before and after aging was calculated according to the formula.
