JD-80B
(Modified aluminum silicate exclusively used in cable material)


.Property and Application
JD-80B, a modified aluminum silicate exclusively used in cable material, is a functionslity addityve by our selecting superior coal series kaolinite through the process of superfimely grinding, refimement, calcination, and modification. It is mainly applied in PVC cable material's formulation to improve product's insulativity.
The main cenefits are:
It has unique specific surface area and porous microchip structure and it can improve greatly product's volume electric resistance ratio and reduce the loss of electrical energy.
It has the capacity of absorbing or intercluding free ion and it can ameliorate product's thermal stability and ageing resistance.
Its particle is superfine and can easily disperse in basal body and it can improve product's smoothness and mechanical property.
It can make cable get long-term dielectric stability property,especially under moisture condition.
