This Nano-Precipitated Calcium Carbonate
(NPCC) product has wide applications in
rubber. Advantages of NPCC-501 usage
include high loading level, increase
reinforcement, and improved other
mechanical properties, etc.
To achieve desirable performance, NPCC-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
NPCC-501 arises from the physical
entanglement from linkages in the polymer
and chemical reactions arising from
surface modification.
NPCC-501 can improve hardness, tensile
strength, elongation at break, tearing
strength and Akron abrasion in rubbers and
thermoplastic elastomers.
In many cases, NPCC-501 can be used to
replace existing reinforcement agents
either partially or completely.
