Product Overview

Silicon dioxide surface modification can reduce the surface energy, improve dispersion and increase compatibility with the substrate. Nanosilica surface is rich in silica hydroxyl, modification modification methods, mainly divided into physical modification and chemical modification of two categories. Physical modification is mainly through electrostatic adsorption, coating and coating and other physical effects on the surface of the particle modification; chemical modification that is, through the inorganic particles of silica hydroxyl and the chemical reaction between the modifier, to change the surface structure of the silica particles, to achieve the purpose of surface modification. Chemical modification generally adopts three ways: coupling agent method, surface grafting method and one-step method.  γ-Aminopropyltriethoxysilane (KH550) is a colourless, transparent liquid with good solubility in water and organic solvents.KH550 is used to improve the surface properties of silica nanoparticles by converting them from hydrophilic to hydrophobic, thereby improving their dispersion and stability in various applications.

Product Features


 

Enhanced hydrophobicity: The surface lipophilicity of the silica nanoparticles is significantly increased by the KH550 modification, which allows them to perform better in many applications where hydrophobicity is required. 

Improved dispersion: KH550 effectively prevents agglomeration of the silica nanoparticles and improves the dispersion of the material, which is essential for improving the overall performance of the composite. 

Improved mechanical properties: The modified silica nanoparticles show better dispersion and stability in the composite material, which enhances the mechanical strength and durability of the material. 

Stability and electrical insulation properties: KH550-modified silica nanoparticles maintain stable properties at high temperatures and also have excellent electrical insulation properties due to their hydrophobicity, which gives them a wide range of applications in the electronics field.

Application Fields

Oil-water separation: KH550 modified nano-SiO2/PU composite membrane is used for oil-water separation, showing efficient separation effect. 

Polymer composites: In plastics, rubber and other polymer materials, it is used as reinforcing filler to improve the mechanical properties, thermal stability and wear resistance of the materials. For example, it is used to manufacture high-strength engineering plastic parts, or to improve the tear resistance of rubber. 

Paints and coatings: Improve the adhesion, weatherability and corrosion resistance of paints. For example, in automotive coatings, to enhance the bonding between the coating and the metal substrate, and to extend the service life of the coating. 

Adhesives: Improve the bonding strength and durability of adhesives. In structural adhesives, to ensure that the bonded joints can still maintain good performance in harsh environments. 

Electronic materials: used in the preparation of electronic packaging materials to improve their thermal conductivity and electrical insulation properties.

Quality product for the right dog...
Color: Orange
Honestly it's a really cool product well constructed and moves around on its own with several different modes. The design id brilliant with a tough rubber ball that unscrew to expose the element that makes it move in the middle. The dog won't be able to unscrew it but you can if you ever need to replace the ball for any reason but it would take some work for a dog to destroy the outer ball. Almost like "Kong" type material. The ball is about the size of a softball and the element inside is about the size of a golf ball. I thought my dog would love this but she was afraid of it, which is strange because she's afraid of nothing. Anyways I gave it to my neighbor upstairs and she has a yorkshire terrier who plays with it all the time so it all worked out great. Quality product . Good job!

Thought it was a good idea but not for my dog
Color: Blue
Seemed great but my dog continued to bark at it. Finally she hid it and I haven’t looked for it.

Durability
Color: Blue, Color: Blue
won’t give this product 1 star because my dog still had a good time with it for a few hours. After opening and preparing it, I gave it to my dog and it definitely caught his interest. However, when he chewed on it, plastic pieces started breaking off and he began swallowing them. This product is definitely not suitable for aggressive chewers.

Winner !!!
Color: Orange
This amazed us. For perspective, we're talking about a three year old white german shepherd who if he's in the mood, has and can kill a toy within minutes or oddly enough be gentle with furry balls and carry them around as if they are his babies. He's an odd duck. Anyway, since he was a pup, and to this day, he'll play and entertain himself, he'll grab a ball, throw it up in the air, then pounce on it as if it's from outer space. It's really quite cute and funny. Because of those two things I was looking for something interactive that would entertain him and confuse him....let's be honest, watching a confused dog is one of life's great pleasures. I tried two other interactive balls and they were crushed immediately. After reading a lot of reviews, people with german shepherds said this ball actually had a life span. I thought the third time could be the charm and ordered one. Well, I think it actually may be from outer space because he's obsessed with it and hasn't taken a bite out of it. He hasn't once chewed it or even teared little pieces off. The three settings are great. Sometimes he likes one better than another, then forgets about the others. I'll change it up to one he hasn't seen in a while and the whole game starts over again. He'll throw it up in the air as he does with his others, watch it and try to figure out which way it's going to go. And yes, he will pounce on it if he times it right. The size is perfect, it's heavier than your average ball but, that's what make it sturdy. I have to sneak it away when he isn't paying attention to charge it, otherwise he'll sit, stare and cry if he knows it's on the counter charging. It's a lot of fun for all of us. I'm so happy I bought it...... I say give this ball a chance even if you have a beast with killer instincts. I'm buying another for a friends 2 year old golden retriever granddog. Thank you Cheerble.

Awesome for hyper dogs
Color: Blue
AWESOME - I have a dog that just won't stop trying to get me to play with him ALL day! I turn this thing on and he goes nuts and tires himself out...without any help from me. The cover got torn off and torn up in minutes but he doesn't care. He just wants this ball. My other dogs, who are older, aren't really interested. But if you have a hyper dog this is the thing for you and them!
