Cable grade calcined kaolin

Cable grade calcined kaolin


[Product Description]

calcined kaolin used in rubber cable materials, due to the combination of wet

and dry application of new technology and high-temperature calcination, the product has

a high porosity structure, can improve the electrical cable insulation properties, excellent

dispersion and good compatibility in the rubber system, improve the cable materials mechanical

properties.


calcined kaolin product calcination temperature is reasonable, the product

structure with high porosity, large surface area, used in rubber or plastic cable materials

not only significantly improve the electrical insulation properties but also to improve the

mechanical properties of the product.
calcined kaolin product ultrafine particle size, in the rubber compound has good

compatibility, halogen-free flame retardant cable compound can partially replace expensive

aluminum hydroxide, improve the mechanical properties of the product , reduce overall costs.
calcined kaolin particle size is appropriate, excellent dispersion in rubber compound

with good reinforcement effect, good cost-effective is the first choice of low voltage level rubber

cable filler.
calcined kaolin is the surface special treatment products, in the plastic system compatibility

with good dispersion, can significantly increase the plastic cable materials for electrical insulation

and mechanical properties.
