Tear Resistance Calcium Carbonate CaCO3 Rubber Filler For Tires
Product description
Filling Agent , CaCO3, White powder , Used In Rubber Compound And Coating.
Recommendations and Applications:
This product is of compact crystal structure , with little impurity , smooth surface ,
uniform particle size, with good processability , good flowablity and dispersablity , l
ow oil absorption , etc.
1. It is used as filler in rubber compound , improve products’s performance on tensile strength ,
hot resistance , aging resistance , tear resistance , reduce production cost.
2. When CaCO3 is used in plastic composite material , will obviously increase interface bonding
strength and mechanical properties. It is widely use in all kinds of plastic products like pipe,
type material , degradable plastic wires and cable, plays a role as toughening and
reinforcing agent , improves luster and quality , etc.
3. CaCO3 is also used in coating industry, increase the thickness of coating layer ,
improve abrasion resistance , at the same time increase coating ratio and spraying area.
In addition , it does not contain heavy metals , is the first choice of powder coating.
