Light Calcium Carbonate for Rubber Shoe Soles

1.Purity::99.2%, Whiteness:95 2. ISO9001 certified, self export right 3.Size(mesh):800~1000 4.Oil absorption:38, moisture:0.3

Our Precipitated Carbonate is as a filler mainly used for rubber, such as rubber shoe soles, rubber tyre, rubber runway etc.

Using PCC in rubber will increase the capacity and save the rubber cost. Besides, it also enhance tensile strength, abrasion and tearing strength.

Features:

High whiteness ,fine grain size,low impurity, adopting dry surface treatment technique,with high activation rate.
