Carbon Black Supplier in Malaysia: ASTM N220, N330 and Pigment Grades
- Also known as
- N330
- N220
- Pigment Black 7
- Lamp Black
ChemTrade supplies carbon black to rubber compounders, plastics processors and ink and coating formulators across Malaysia. We carry the ASTM N-series rubber grades, N220 and N330, in bags, and source other designations and pigment and conductive grades to order.
In rubber it is the reinforcing filler, and the designation is the whole decision. N330 is the high abrasion workhorse that disperses easily, N220 reinforces harder for tread and wearing parts, and the coarser grades from N550 upward trade abrasion resistance for loading and extrusion.
Outside rubber it is bought for colour and for conductivity. Pigment grades go into masterbatch, coatings and printing inks on jetness and dispersion, while conductive grades make a polymer antistatic at a loading set by the resistivity the part has to reach.
Handling is dusty and fine black gets everywhere, so gloves, glasses and a mask are needed and the charging area wants ventilation. Ask for the safety data sheet with your enquiry and read the exposure limit off it.

Carbon Black grades and forms
We supply several forms to suit different formulating and dosing setups. If you need a size that is not listed, ask us.
| Grade | Form | Assay | Typical use | Packing |
|---|---|---|---|---|
| N220 | pellets or powder | — | Intermediate super abrasion furnace black, the higher reinforcing of the two rubber grades we carry. Tread compounds and other parts where abrasion resistance and tensile strength decide service life. Harder to disperse than N330 and it builds more viscosity in the mix. | 20 kg bag |
| N330 | pellets or powder | — | High abrasion furnace black, and the general workhorse of rubber compounding. Tyres, hoses, belting, mouldings and extrusions, where it balances reinforcement against ease of dispersion and mixing cost. Start here if a compound does not specify a grade. | 15 kg bag |
| Semi reinforcing grades | pellets or powder | — | The coarser end of the N-series, N550 through N774. Used where the compound needs loading, extrusion smoothness and low cost more than it needs abrasion resistance. Send the designation your compound calls for and we will source against it. | bags |
| Pigment grades | powder | — | Colour rather than reinforcement, for masterbatch, plastics, coatings and printing inks. Bought on jetness and dispersion, and the fine particle blacks that reach the deepest black are the hardest to disperse, so the choice follows the mixing equipment. | bags |
| Conductive grades | powder | — | Used to make a polymer conductive or antistatic rather than to colour it, in cable compounds, antistatic mouldings and conductive coatings. Loading is set by the resistivity the part has to hit, so tell us the target. | bags |

Carbon Black applications
Safety and handling
Store bags in a cool dry place away from oxidisers and from open flame, and keep them closed, because loose fine black contaminates everything near it and does not come off. Handle with gloves, safety glasses and a dust mask, and ventilate the charging area: the dust irritates the eyes and the respiratory tract, and inhalation over a working life is the exposure the limits are written for. Ask for the safety data sheet with your enquiry.
Common questions about carbon black
Which grade do I need, N220 or N330?
N330 unless your compound says otherwise. It is the general purpose high abrasion black and it disperses more easily, which keeps mixing cost down. N220 gives more reinforcement and better abrasion resistance, so it goes into tread and other wearing parts, at the price of a stiffer mix that is harder to disperse. Send us the compound or the property you are trying to hit and we will say which one fits.
What is the difference between carbon black and activated carbon?
They are different products for different jobs. Carbon black is made by burning hydrocarbons under control and is bought for reinforcement and for black colour, so what matters is particle size and structure. Activated carbon is made from coconut shell, coal or wood and is bought for adsorption, so what matters is pore volume and surface area. If you need to strip colour, odour or contaminants out of a liquid or a gas, you want activated carbon and we supply that separately.
Do you supply N550, N660 or another designation you do not list?
Ask. We are a trading house rather than a producer, so the grades we have moved recently are not the limit of what we can bring in. Send the ASTM designation, the quantity and the delivery point, and we will confirm what can be sourced and on what timescale before quoting.
Can you supply pigment or conductive grades rather than rubber grades?
Yes, and they are chosen on different numbers. Pigment blacks are specified on jetness and on how readily they disperse in your system, and conductive blacks on the loading needed to reach a target resistivity. Tell us the polymer or the coating system and the property you have to meet, because the right answer depends on your mixing equipment as much as on the black.
What packing is available?
Bags, and the size follows the grade because a fluffy black fills a bag that a pelletised one would not. What we have moved is 15 kg and 20 kg. Larger jobs are quoted in bulk bags or by the pallet, so tell us the tonnage and we will price the packing that suits it.
Will you send a safety data sheet and a certificate of analysis?
Yes, ask for both with your enquiry and we will send the safety data sheet and the batch certificate for the grade being quoted. Check any figure your compound depends on, iodine number, DBP absorption, surface area or ash, against that certificate rather than against a web page.
How is carbon black priced?
By the tonne and by grade, on enquiry. It is made from oil feedstock, so the price moves with the feedstock and with freight, and a published figure would be wrong for most enquiries. Send the designation, the quantity and where it is going and we will quote a current price with a stated validity period.
