¢ñ .Property and Application
JD-80A, a modified aluminum silicate exclusively used in cable material, is a functionality additive by our selecting superior coal series Kaolinite through the process of superfineness, refinement, calcination, and modification, It is mainly applied in EPDM cable material's formulation to improve product's insulativity. The main benefits are:
¡ô It has unique specific surface area and porous microchip structure and can improve greatly product's volume electric resistance ratio and reduce the loss of electrical energy.
¡ô It has the capacity of absorbing or intercluding free ion and can ameliorate product's thermal stability and ageing resistance.
¡ô Its super fine particle can easily disperse in basal body and it can improve product's smoothness and mechanical property.
¡ô It can make cable get long-term dielectric stability, especially in the moisture condition.
