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.

Small but holds alot
Color: Large Coffee
Love this bag! Dis a bit of research as I wanted a zipped bag, with outside pockets for my phone and not those inner pockets for holding credit cards. This is perfect for me. Very nicely put together and is a perfect color of brown. I will be using this alot.

Can’t Open Zipper All the Way!!
Color: Large Coffee, Color: Large Coffee
There is a bizarre piece of metal attached to zipper that prevents the bag from opening all the way. I bought one of these purses last year and it did NOT have this, so the bag opened completely. However, the leather is showing wear so I decided to buy another one, this time in dark brown. When it came, I noticed that the silky satin lining had been replaced by cheap, rough, dull material. I guess that’s okay, even though they raised the price $10. The zipper thing though, no way. I need my purse to be able to open all the way. I sent it back, to be replaced with the exact same item. Just got it today and it still has that metal piece on the zipper!! What the hell?! I included a pic of my old purse showing it zipped all the way open, and the new purse with the zipper stopped about 1.5 inches from the end. I truly don’t understand, but it’s going back again.
