Color and Size
With the process of removing sand and impurity, crashing, filtrating, vermiculites become exfoliated, they can be divided into different sizes: 1-2mm, 2-4mm, 3-6mm, 6-8mm and so on, we can produce many sizes as clients required. There are two kinds of vermiculite in our country golden vermiculite and silvery vermiculite, they have different chemical components.
Product Properties Features
Expanded vermiculite has the following properties and characteristics:
High temperature expansion: when heated to 300℃, the volume can expand more than 20 times, forming a lightweight porous structure.
1.Excellent heat preservation and insulation performance: low thermal conductivity, with good heat preservation and insulation effect.
2.Fireproof performance: non-combustible, suitable for occasions with high fireproof requirements.
3.Environmentally friendly and non-toxic: natural mineral, non-polluting, friendly to human body and environment.
Application Areas
Expanded vermiculite is widely used in the following fields:
Building materials: to make lightweight concrete, sound insulation boards, fire prevention boards, etc.
