Product Name

Name:Calcium Carbonate Nanopowder


Product Overview

Nano calcium carbonate is a new type of lightweight calcium carbonate products, due to the ultrafine calcium carbonate particles, fine and uniform particle size, narrow distribution, large specific surface area, surface activity and dispersion of good, high surface energy, so that in actual use embodies a lot of ordinary calcium carbonate materials do not have more excellent performance, more widely used. The main synthesis methods of calcium carbonate nanoparticles are carbonation method, precipitation method, etc. The produced calcium carbonate mainly exists in the form of calcite, and its particle size ranges from dozens to hundreds of nanometres. In the polymer melt, the agglomeration of the filler powder will adversely affect the performance of the material, so it is necessary to carry out surface modification of calcium carbonate nanoparticles before filling. Some commonly used surfactants are silane coupling agents, stearic acid, aluminates/titanates coupling agents, etc. These coupling agent molecules usually contain both hydrophilic and hydrophobic groups, which, combined with the groups on the surface of calcium carbonate, are able to reduce the surface energy of the calcium carbonate nanoparticles and improve their dispersion properties.

Product Features

1）Low water content, nearly neutral, and has good chemical stability, do not react with the curing glue in adhesives.

2）The large amount of addition can greatly reduce the cost of adhesive products (for example, the amount of silicone rubber sealant is more than 50%, and the amount of polyurethane adhesive is 20-30%).

3）With reinforcing effect, can improve the mechanical properties of the adhesive, reduce the shrinkage and thermal expansion coefficient, increase the thermal conductivity, improve heat resistance and adhesion force, improve the mechanical strength (hardness and compression strength) and corrosion resistance; can also lubricating the adhesive, improve the operation conditions, and improve the bonding performance.

4）Nano calcium carbonate has small particle size and large specific surface area, and has good solubility with the adhesive after certain surface treatment. It can be used as a thielectric agent in the adhesive system to adjust the viscosity of the adhesive, prevent the adhesive from sagging during the vertical surface construction, and improve its retention characteristics.

5）In the process of making color material, nano calcium carbonate is easy to color and will not affect the color of the product.

6）It has different modification effects in different adhesives, which can improve its rheological properties in PVC plastic sol; increased strength and wear resistance in silicone structural sealant; incremental reinforcement and heat resistance in hot melt adhesive; and thickening and adhesion in water-based adhesive.


Application Fields

1）Plastics industry: As a filler and enhancer, nano-calcium carbonate can improve the rigidity, toughness and heat resistance of plastic products, and improve their processing performance. For example, adding a small amount of light calcium carbonate to PVC products improves the tensile strength.

2）Rubber industry: Nano calcium carbonate used in high-performance tires, auto parts, bicycle tires and running shoes and other products, can increase the strength, rigidity and durability of the product.

3）Paper industry: used as a filler, nano calcium carbonate can improve the brightness, whiteness and flatness of paper, suitable for advanced packaging paper.

4）Patings and inks: Adding nano-calcium carbonate to coatings and inks gives the coating better gloss and durability, while reducing production costs.

5）Pharmaceutical industry: nano-calcium carbonate, as an important component and calcium source additive in the culture medium, is also used in the production of antibiotics, painkillers and gastric drugs.

🐾Ridiculous aggressive chewer🐶
Style: Stick, Flavor Name: REAL Bacon, Size: Medium
Sooooo happy I finally found something that my moms pup couldn't chew up! Not going to like its been very tough. She has now for at least a week (sorry days pushing together 🤪) Let's just say the pup is a chihuahua mix that LOVES to chew. Emphasis on the chewing youre lucky if a toy lasts more than a day let alone a week 🤣 This is so durable I may not need one for her for a while but this will come HIGHLY recommended for ridiculously aggressive chewers. Suitable for ang size dog just make sure you go one size bigger then you think you should. Quick easy chew toys but definitely has some weight to it.

Stands Up to Strong Chewers Without Splintering
Style: Stick, Flavor Name: REAL Maple Wood, Size: Giant
We got the Benebone Maplestick in Giant size for our large, aggressive chewer, and it has held up remarkably well compared to other chew toys we’ve tried. The real maplewood core mixed with durable nylon offers a satisfying chew texture; it feels substantial without being brittle, and our dog goes after it consistently during free play or after meals. It’s noticeably tougher than many rubber or soft plastic toys, yet it doesn’t splinter into sharp pieces, which gives me confidence in regular use. The shape and size are also well suited for bigger mouths, and the way it’s angled makes it easy for a strong chewer to get a grip and work away at the surface. Cleaning is simple, and over weeks of use we’ve seen only normal wear rather than shredding or chunks missing. As someone who’s tried multiple toys claiming “for aggressive chewers,” this one genuinely lives up to its reputation in my experience. While no chew toy lasts forever with a powerhouse chewer, this one’s longevity feels above average without resorting to metal or stone alternatives that can be too hard on teeth. For everyday chewing and play, it strikes a solid balance of durability and engagement.

Our dogs love them and they hold up well.
Style: Fishbone, Flavor Name: REAL Jack Salmon, Size: Large
The dogs love them and are very durable! I recommended to a friend who has a strong chewer and his dog loves them too. They like all varieties but particularly the fish flavored ones. Any kind of chew toy made out of any cloth even cordura is ripped up in minutes but they chew on these for hours.

Dog LOVES this bone & great value.
Style: Tripe, Flavor Name: REAL Beef, Size: Medium
My dog absolutely loves this bone! She chews on it with "furvor" and never grows tired of it. It lasts a very long time, several months and is a great value for the money. She chews it every day and it keeps her busy. It is hard but is able to be chewed with no problems. This is the third Tripe Benebone she has had. It's her favorite out of all the Benebone varieties. She hasn't had any negative reactions to it. After it has been chewed, the surface does get prickly, so I'd recommend being cautious not to step on it in your bare feet!

Doesn't really taste like bacon. I know becaused I chewed it. Great as a slower eating thingy.
Style: Dental Chew, Flavor Name: REAL Bacon, Size: Dental Medium
So my dog has this thing where she does not want to chew on anything that she is supposed to chew on unless it's a knuckle bone that she cannot be trusted with (because she bites off fragments of bone) or one of those flexible, edible nylabones for "gentle" chewers, which she will eat in a single sitting. If I want to get her to chew something that might actually withstand her for more than an hour, I have to pretend it's mine. It's a secret forbidden treat that I love very much and just "accidentally" left within her reach to steal and covet. So it's pretty much standard practice at this point that, when I get her a new chew toy, I gotta carry it around for a while, pretending to chew on it. I got this bone in the mail and did exactly that, but I noticed right off the bat that, for a bacon-flavored thing, it didn't smell like anything at all. It was just this plain sort of plastic scent. And that's how I ended up actually chewing on it instead of just miming it out because maybe the bacon flavor was under the initial layer? But no, it wasn't. It was just bacon-colored plastic. So if your dog is the type of chewer that will chew regardless of flavor, this should work out fine. If not, go for something else. My dog did not give a heck about this bone, even once the "this is actually mine but you cleverly stole it away" ritual was completed. After that, I tried putting it in her bowl with her food, thinking maybe the flavor of the food would rub off enough that she'd want to chew it. She didn't, but what did happen is the reason I'm giving this a positive review at all. While it fails utterly as a chew, it makes a really great impromptu "stop eating so fast, you tornado shaped like a dog" mechanism. We've bought actual slower eating bowls for her and never had any success, because she just gives up and cries if she can't get her face into the crevices. But when we put this in her regular round bowl and pour her wet food around it, she's able to nose the benebone around in the bowl as she eats her food, but it does slow her down considerably. She's way less farty and whiny after food time, which anyone who has experienced how specifically racid dog farts can be will know is a blessing. So, thanks, Benebone. For us, your product is worthless as a chew, but invaluable as a makeshift slower eating thingy. Edit: Benebone got in contact with me about my review and offered to refund my purchase and send me some different products to try. I declined the refund, because I do find the bone I bought useful for the above-described purpose of slowing my dog down when she eats. But I did accept the samples. She's still pretty unimpressed with them, and I will probably end up passing them along to other dog-havers I know, but I myself am pretty impressed with Benebone's customer service and so have changed my review from 3 stars to 4. It was "suggested" that I mention that other dogs will probably be more satisfied with Benebone's flavors if they are not as picky as my dog is, and that sampling a Benebone yourself is maybe not the most reliable way to test its tastiness, when dogs have much more sensitive noses/tongues than humans. Which is certainly true! But I don't think my dog is a complete alien for wanting something with slightly more discernible flavor and scent. And I do think some of the advertising for Benebone implies more of that than you actually get in the finished product. So I'm gonna have to double down on my previous assessment that, if your dog likes to chew for the sake of chewing, Benebone will probably really appeal to them. But if they're a more food-motivated chewer, you're better off with fully-edible chews like rawhide or bully sticks.
