Expanded Vermiculite - Expanded Volume 8-25 Times, Soft Texture With Excellent Sound Absorption Performance

Expanded Vermiculite is a secondary modified mineral of water aluminate containing magnesium in a laminar structure, and its volume can be increased by 8-25 times, and its color turns golden or silvery white under condition of baking at the temperature range of 800-1000 a , and then an expanded vermiculite in loose structure is generated. It can be used in friction materials, sealing materials electrical insulation materials, paint, plates, varnish, rubber, fire resistant materials, hard water softener, as well as in the industries of smelting, construction, shipbuilding, and chemicals etc.

Expanded vermiculite is widely used in friction material at present, and provided with a soft texture, a hollow structure, and excellent sound absorption performance, so it can effectively reduce braking noise and the specific weight of products.
