Carbon black N375 is a rubber-processing grade defined by a specification table covering iodine adsorption, oil absorption (DBP), tint strength, pellet hardness, pour density, ash content, heating loss, pH value, pellet fines, sieve residue and toluene extract transmittance. Each property is stated on the certificate of analysis for the batch supplied.
Carbon black N375 is a rubber-grade reinforcing carbon black supplied by BHD Chemical, part of the N-series carbon black range. We deliver it on spec and on time, with each batch backed by documentation tying every property to the certificate of analysis.
