NCC-501 FOR NATURAL AND SYNTHETIC RUBBER
This Nanometer Calcium Carbonate (NCC) product has wide applications in rubber. Advantages of NCC-501 usage include high loading level, increase reinforcement, and improved other mechanical properties, etc.
To achieve desirable performance, NCC-501 can be used as a partial or complete replacement of fillers; fumed silica or carbon black (Thermal or Normal) and is applicable in natural and synthetic rubbers like EPDM, NR, SBR, BR, SBS, Silicone and light/colored rubber products. The reinforcement effect of NCC-501 arises from the physical entanglement from linkages in the polymer and chemical reactions arising from surface modification.
NCC-501 can improve hardness, tensile strength, elongation at break, tearing strength and Akron abrasion in rubbers and thermoplastic elastomers.
In many cases, NCC-501 can be used to replace existing reinforcement agents either partially or completely.
