Carbon Black for Rubber and PVC Shoe Soles

Black Gold Chemicals manufactures modified carbon black for shoe soles. Used with SBR and BR rubber, and in PVC soles, our grades raise sole hardness, improve wear resistance, and give a deep, even black, consistent from batch to batch.

What sole producers need from carbon black

A shoe sole is judged on how long it lasts and how it looks. The carbon black in the compound affects both:

• Hardness that matches the sole design
• Abrasion and wear resistance for longer service life
• A deep, even black surface with no grey patches or specks
• Good dispersion in the mixer, so every batch behaves the same

What our shoe sole grades deliver

• Higher hardness: carbon black raises the hardness of rubber and PVC soles.
• Better wear resistance: reinforcement that helps soles resist abrasion and last longer.
• Made for SBR and BR compounds: designed to work with styrene butadiene rubber and butadiene rubber.
• Deep black color: an even black finish on the sole surface.
• Batch-to-batch consistency: every batch is produced to defined parameters.
• Custom adjustment: the grade is adjusted to your compound, process, and target hardness.

Applications

• Rubber shoe soles (SBR and BR compounds)
• PVC soles
• Safety and work shoe soles
• Sports and casual footwear soles
• Slippers and sandals

Tips for consistent soles

1. Add the carbon black at the same stage of mixing in every batch, and keep mixing time and temperature constant.
2. Good dispersion matters as much as dosage. Poorly dispersed carbon black can show as specks and weaker wear resistance.
3. Measure hardness on fully cured soles and adjust the dosage to reach your target.
4. Keep the rest of the formula constant when you compare grades, so the result reflects the carbon black.

How to get started

1. Tell us your sole type, compound, process, and target hardness.
2. We recommend the right grade and a starting dosage.
3. We send a free sample with its TDS and SDS.
4. You run a trial on your line, and we help fine-tune the dosage.
5. Regular supply at the same specification, batch after batch.

Frequently asked questions

Why add carbon black to shoe soles?

Carbon black reinforces the sole compound. It raises hardness, improves wear resistance, and gives the sole a deep black color.

Does it work in both rubber and PVC soles?

Yes. We supply carbon black for rubber soles based on SBR and BR, and for PVC soles.

How much carbon black should I use?

It depends on your compound and target hardness. After reviewing your formula, we give you a starting dosage and help you adjust it on a trial batch.

Do you provide a TDS?

Yes. Once we identify the right grade for your application, we send its TDS and SDS.

Can I get a free sample?

Yes. Contact us with your application and we will send one.
