BHD Chemical, part of BHD Group, supplies carbon black N330, an N-series carbon black, against the BHD technical data sheet. The spec table gives iodine adsorption, DBP oil absorption, tint strength, toluene extract transmittance, ash content, heating loss, sieve residue, pour density, pellet hardness and pellet fines. N330 is quoted on request by volume and destination.
Carbon black N330 from BHD Chemical is an N-series carbon black supplied against a published technical data sheet: iodine adsorption, DBP absorption, tint strength, pellet data and impurity limits are all set out in the BHD TDS. We quote every order on request, stating grade, volume and destination plainly. BHD Chemical and BHD Sourcing are two divisions, one house, and one accountable house stands behind your supply.

Carbon black N330, specified before it is quoted
Carbon black N330 is an N-series carbon black. Compound engineers and procurement teams know it by its iodine number, DBP absorption and tint strength. BHD Chemical supplies N330 against the ranges in the BHD technical data sheet, so you can check the grade against your own qualification before you ask for a price.
The spec table on this page gives every value from that TDS. We do not round or restate them. If a figure is not on the sheet, we do not claim it.
What the compound engineer checks
The TDS covers the properties a rubber compounding lab compares first: iodine adsorption, oil absorption (DBP), tint strength against IRB3, and toluene extract transmittance. It also sets limits for ash content, heating loss and sieve residue. Put these ranges next to the ones your compound is qualified on, then request the TDS and a sample for lab work.
What the mixing room checks
Operations supervisors care about how the pellets convey and dose. The TDS gives pour density, individual pellet hardness and pellet fines, together with the heating loss limit. If your conveying or bulk handling line has particular requirements, include them with your quote request. We will review them against the spec before we commit.
One accountable house behind your supply
BHD Chemical sits within BHD Group, alongside BHD Sourcing. You deal with one accountable house. The same team answers for the grade, the quote and the delivery terms. We commit only to what we can deliver on spec and on time, and we put it in writing in the quote.
How to request a quote
Send us the grade (N330), your volume, your destination and the Incoterms you prefer. We will reply with a written quote. If you are still qualifying the grade, ask for the N330 technical data sheet first. You can see the rest of the carbon black range, and the other product families, on our products page.

Frequently asked questions
What documentation comes with a carbon black N330 order?
Every batch ships with a certificate of analysis covering the properties on the specification table, so you can verify the material against your own requirements before it enters production.
What form is carbon black N330 supplied in?
It is supplied in pelletized form, which limits dust and improves handling during compounding.
Can BHD Chemical confirm a specific property before I order?
Yes. Specific values are stated on the certificate of analysis for your batch; contact BHD Chemical with your requirements and we will confirm against the specification table.
What industry is carbon black N330 used in?
It is used as a reinforcing filler in rubber compounding for the tyre-rubber industry.
