Product Features

1)Chemical inertia: Fumed silica is chemically inert and is not easy to react with other substances, which makes it stable in a variety of applications.

2)Surface hydroxyl: the surface contains silanyl and hydroxyl, these functional groups enable it to form chemical bonding with other materials, thus enhancing the properties of the material.

Application Fields

1)Rubber industry: as a reinforcing agent of silicone rubber, it can significantly improve the tensile strength, tear resistance and wear resistance of rubber products.

2)Coating industry: used as a thickening agent of unsaturated resin, as well as the coating of anti-sink, thickening, anti-flow hanging AIDS.

3)Plastic industry: as a plastic filling agent, it can improve the mechanical properties and processing properties of plastics.

4)Ink industry: used as a thickener of ink, can improve the ink touch degeneration and stability.

5)Other fields: it can also be used as metal soft abrasive, insulation and insulation filler, advanced daily cosmetics fillers and spraying materials, medicine, environmental protection and other fields of additives or catalyst carrier.

Super cute, comfortable, practical, love that they are slip on
Size: 10.5, Color: Tobacco/Black
I have worn these 2-3 times already. The first day was a school/work day so I was on my feet 9 hours and the only issue I had was with the side of the boot rubbing against my ankle. I just make sure I wear socks high enough to cover my ankles or jeans that go into the boots now for long wear days. Absolutely love them! They keep my feet dry in this snow( we live in Michigan). I had been looking for a pair like this for awhile now and was getting super frustrated that I couldn't find my size in any that I liked. I saw that they had these available in a 10.5 and I wear 11. I looked at the Sorel website reviews (since the amazon ones weren't super helpful on sizing) and they said that the boots ran big so I took a chance on the 10.5 fitting me. They fit perfect. I have long narrow feet but I could see where they would be tight or uncomfortable on someone with wider feet. I've been trying to find a pair for my mom now since she has boot envy.

Fantastic Boots!
Size: 8.5, Color: Redwood/Gum 10
Completely satisfied with these boots. True to size, well made, comfortable from the get-go; not break in needed. Waterproof- really. The Red Suede has withstood a nasty winter season & still looks great. Good traction. I like the ankle height which looks good with long, mid length pants & leggings. I love the easy slip on/off aspect..made getting ready for dog walking easy. I 100%recommend!

Definitely worth the price
Size: 6.5, Color: Black/Black
Absolutely love these boots! I originally bought them to wear in NYC in December & they did not disappoint. They were comfortable, cute, durable and worked well in the slush/snow. The traction on the bottom is also nice! They kept me warm with wool socks. I wear them almost daily now. Perfect for everyday. easy to wear with variety of outfits. Good every day shoe.

Snagged a deal
Size: 7, Color: Redwood/Gum 10
I waited and waited to get these boots! I knew I was chancing it, but they went on sale, and I snagged them! I am a size 7, and they fit nicely with socks. a little loose, barefooted, but what psycho wears boots without socks? They are comfortable and really well-made.
