Sillikolloid P 87 is a natural agglomerate of corpuscular quartz and lamellar kaolinite. These two elements together form a lose structure which offers particular advantages in terms of application possibilities when used as a functional filler.
* Applications:
In elastomer applications Sillikolloid P 87 can be used as a functional filler either on its own or in combination with other non-reinforcing or reinforcing fillers.
In general Sillikolloid P 87 is suitable for any rubber products used for technical applications. Its particular properties are high tensile strength, high tear resistance and excellent extrusion properties. Used in black profiles and hoses it has a slight matting effect. It is equally suitable for black and colored compounds. |
