Carbon black pellets pouring from a steel chute into a weigh hopper
FIG. 01 · N375 · Iodine adsorption number 90 ± 5 g/kg

N375 carbon black is in the same particle size class as N339 but has a lower structure (OAN 114 ml/100 g). This means the compound can take more oil, and swell stays low despite the high oil loading.

Why oil loading capacity matters

High oil loading capacity both lowers cost and improves the processability of the compound. This property of N375 is valuable in applications that are sensitive to both performance and cost, such as tread base layers and conveyor belt compounds.

Applications

Tire treads, conveyor belts, mechanical rubber goods.

How does it work?

Frequently Asked Questions About This Product

Why does N375 allow high oil loading?

Although it is in the same particle class as N339, it has a lower structure (OAN 114 ml/100 g). Lower structure means the compound can take more oil, and swell stays low despite the high oil loading.

In which applications is N375 an advantage?

In applications that are sensitive to both performance and cost, such as tread base layers, conveyor belt compounds and mechanical rubber goods.

What packaging is N375 available in?

We offer two options: a 1,000 kg double-valve PP-PE jumbo bag and a 21 kg two-ply kraft paper-PE bag. A pallet of bags holds 1,155 kg of product; a 20' container takes 9,240 kg and a truck 20,790 kg. With jumbo bags, these figures are 10,000 kg and 22,000 kg respectively.

Does N375 come with a certificate of analysis and a safety data sheet?

Yes. Every shipment is sent with a certificate of analysis (CoA) for that batch, issued by an ISO/IEC 17025 accredited laboratory. We send the safety data sheet (SDS) on request; if you would like to see a sample report before ordering, you can ask for one through the quote form.
