BLACKLEAF Tarifs & Verified Deals – August 2026

Reliable graphene source

This isn't my first time ordering from Blackleaf. We've been using their graphene nanoplatelets for a while now in our composite materials, and they've always been consistent. This last order for a larger batch of nanoplatelets was just as smooth as previous ones. The quality of the material is always what we expect, which is crucial for our production. Delivery times are reliable too; it usually takes about a week to get to our facility in Texas. That consistency is why we keep coming back instead of trying other suppliers. They just make it easy.

Got my graphene powder fast

Needed some graphene powder for a prototype, so I put in a request with Blackleaf. The whole process was pretty easy. Got a quote back in a few days, then placed the order. It showed up at my workshop in Oregon in about 6 days, which was quicker than I thought it'd be. The powder looked good, did what I needed it to do. No complaints, felt pretty good about the whole thing.

Decent ink, slow communication

I purchased a small quantity of their solvent-based graphene ink for a research project. The product itself seems good, it integrated well into our system for flexible electronics. The performance was on par with what they advertised. However, getting the initial quote took longer than I expected, around five business days, which held up our procurement a bit. Once the order was placed, shipping was efficient, arrived in about a week. I appreciate the quality of the ink, but an improvement in their quote response time would make the overall process much smoother.

Graphene additives worked well

Ordered graphene additives. Quote was clear. Delivery took 5 days to reach Denver. Product was high quality, exactly as described. Used it for polymer reinforcement, saw good results. No issues with the order or product. Efficient service.

Good product, solid support

I ordered a sample of their water-based graphene ink to test in our printed electronics setup. The quoting process was straightforward, took about two days to get a detailed response. Delivery to our lab in California was surprisingly quick, about 4 business days after the order was confirmed. The packaging for the ink was very secure, no leaks or damage. We ran some initial tests, and the ink performed as specified in the datasheet. I did have a question about optimal curing temperatures for a specific substrate, and their technical support team got back to me within a day with some helpful suggestions. The usability of the ink was pretty standard for a conductive material, no unexpected issues. Overall, a positive experience from start to finish.

Good value for graphene dispersion

I was looking for a good price on graphene dispersion for a new energy storage application. Blackleaf's quote for a sample felt quite competitive compared to other suppliers I checked. I specifically asked about volume discounts for future industrial scale-up, and they provided clear information on their tiered pricing. The sample arrived promptly, and the quality seems to justify the cost. It felt like a solid investment for the value received, especially considering the potential for larger orders down the line. I always try to get the best deal, and this felt like one.
