Product Overview

Multi-walled carbon nanotubes are made of multilayer coiled graphene sheets and maintain a fixed distance between the layers, forming a coaxial circular tube structure. The tube diameter is usually between 5 and 30nm, and the length can range from a few microns to dozens of microns. The specific size depends on the preparation method and conditions. The purity of industrial-grade MWCNTs can reach 95% or higher, ensuring their stability and reliability in applications. The main preparation method of industrial grade multi-walled carbon nanotubes is chemical vapor deposition (CVD) method. In the process of CVD, carbon source substances (such as methane, acetylene, etc.) are decomposed and deposited into tubular structures under the action of catalysts (such as iron, cobalt, nickel, and other transition metals at high temperature). Precise control of the diameter, length and structural properties of MWCNTs can be achieved by controlling reaction conditions and the use of specific catalysts.

Product Features

 

1)Mechanical properties: Industrial-grade multi-walled carbon nanotubes have extremely high strength and toughness and are considered the super fibers of the future. It is 100 times as strong as steel and weighs only 1 / 6 of steel, giving it great potential for composite enhancers.

2)Conductivity: Multi-walled carbon nanotubes have good electrical conductivity, even better than copper. This makes it widely used in electronic devices, conductive inks, sensors and other fields.

3)Thermal conductivity: multi-wall carbon nanotubes also have excellent thermal conductivity, their thermal conductivity is much higher than the general metals and alloys. This makes it have an important application value in the thermal interface materials, heat dissipation materials and other fields.

4)Chemical stability: Multi-walled carbon nanotubes have good chemical stability and can maintain their stability in a variety of harsh environments.


Application Fields

 

1)Electronic devices: Multi-wall carbon nanotubes can be used to manufacture high-performance conductive inks, sensors, flexible displays and other electronic devices. Their excellent electrical conductivity and mechanical properties enable these devices to have higher performance and longer service life.

2)Energy storage and conversion: Multi-walled carbon nanotubes can be used as electrode materials for lithium-ion batteries and supercapacitors to improve energy storage and power output capabilities. Its high specific surface area and excellent electrical conductivity make the electrode material have higher energy density and faster charge and discharge speed.

3)Composite materials: In composite materials, multi-wall carbon nanotubes as enhancers can significantly improve the mechanical properties and electrical conductivity of materials. They can be added to plastics, rubber, metal matrix, etc., to enhance the strength, stiffness, and thermal conductivity of the material.

4)Other fields: multi-walled carbon nanotubes can also be used as catalyst or catalyst carrier, hydrogen storage materials, thermal interface materials, etc., which has a wide application prospects in chemistry, energy, environmental protection and other fields.

My Dachshunds Love These
Size: Small
These balls are durable, flexible material, highly chewable without being easily destroyed. I stuff them with Milkbone Maro Snacks, which are just the right size to twist into the holes in the ball. My dogs literally get an hour+ chewing and chasing entertainment from these. They chew them, they sometimes 'pop' out of their mouths, go rolling across the floor, dogs chasing them. This satisfies their urge to hunt prey. Dachshunds can easily tear this kind of stuff-it-toy apart. These have lasted for a long time without tearing or shredding. I would NOT recommend them for a dog much larger than a tweenie weenie. They're a bit on the small side and might be swallowed by a larger dog. It would be cool it they also came in a larger size (and probably ball wall thickness also) for the bigger dogs to enjoy. These stuff-it chew balls are better than the kong balls my dogs had before these. Highly recommend them.

My puppy’s favorite fetch toy!
Size: Small
Update Aug 27, 2024: After 10 months, these are still his favorite ball. He’s obsessed with fetching and plays with them all day. They do bounce really high. Unfortunately, the small size aren’t available for sale anywhere anymore. I tried the medium size, and he has a bit of trouble hanging on to them, but he manages. Weirdly, he prefers the orange one, but he also plays with the blue one. My 7 month old Shih Tzu puppy loves to fetch, and these are his new favorites. They’re small enough to fit in his mouth, and they are made of hard plastic, so he’s able to hold on to them. They have a lot of bounce, and this adds to the fun for him. I highly recommend them.

Genuinely bummed that these great balls can’t stand up against my Chloè.
Size: Medium
I love all the Chuckit brand of balls. I found that the Strabo and glow balls in the Chuckit line are the softest, and as such, don't last as long as the rest of Chuckit line of balls. Having said that, they do last longer than than every other brand I've tried (and I do believe I’ve tried every brand available on the market today.) The strato balls do bounce higher than any of the other balls in the Chuckit line. They really are a good value.

Great dog balls at a great price
Size: Medium
The balls are a favorite for my dog. I could have done without the hole through the middle because I don't do treats in balls anyway. My dog loves balls for their own merit. I needed replacement balls for my Nerf Dog Ball launcher. It seems the originals have disappeared from the market. I took a chance because the price is right and this Chuck-it ball works very well so we're liking this ball a lot. So far my Dachsund, who can destroy a tennis ball (the kind they are selling as Nerf Dog replacements) in 3 minutes has not done any damage to this one so that's a win. I recommend this as a much better ball than the fuzzy tennis balls. I like the colors too since many dog toys are green (which gets lost in the lawn, etc.) or red (even though dogs have red/green color blindness. Blue and orange are good and pretty easy to find. I liked these well enough that this set was my second purchase so I will have spares in case the others are lost.

My Baby loves his new baby!
Size: Medium, Size: Medium
Finally! A ball my 107 lb. pitty/pointer mix can’t destroy. He has torn up every single “indestructible” toy in a day or so until now. He peels fabric and fur off non-rubber toys. He is a 4-legged shredder. I’ve added pictures of him for a size reference of my dog versus this product. I know I had wanted that when shopping for this item. This ball is now his beloved “baby.” He goes absolutely insane looking for it, chewing it, chasing it, and even sleeping with it. He won’t rest unless he knows exactly where it is. It is his only toy, and he is good with that. After getting this home, I tried giving him other choices, but he won’t touch them. I was worried that he would rip it apart by putting his teeth in the holes, but so far, not a scratch. It is soft enough to collapse just enough to keep it from cracking when his jaws crush it but not so soft that he can rip it to sheds. The holes are large enough to prevent a suction or vacuum effect on his tongue or mouth. For his size jaws, it is a perfect fit. Other dogs might have problems with suction or be able to get their teeth in those holes and rip it apart. Who knows? The older version of the Chuckit squeaky ball was his favorite for the year and a half he had it, but the way they make them now, he peels off the orange triangle in hours flat, the squeaker falls out (choking hazard), and then he rips it apart. I’m going to stock up on these. I can’t imagine how crazy he will be if they ever stop production or change the materials.
