VERMICULITE
When subjected to a heat treatment at
temperatures over **0°C the mineral expands, multiplying its
volume between 8 and *0 times.Propierties:
Light
weight: The apparent densities of expanded vermiculate range
between **0 and **0 and **0 Kg/m3 depending on their
grades.Â
Â
Â
Heat
insulation:
Expanded
vermiculite keeps its insulation capacity between **0°C and
***0°C. Its heat conductivity is .**3 Kcal/hr m.°C at an average
temperature of *0 °C. Its calorific capacity is very
low.
The shiny walls of the mica
sheets of vermiculite form a variety of screens that reflect and
diffuse heat energy transmitted via radiation, and make this
material a suitable high temperature insulator.
Soundproofing:
It
is an ideal insulator for a wide range of
frequencies.
Resistance
to fire:
Melting
point: ****- 1,**0ºC
Vicat temperature: 1,**0°C
Incombustible and chemically stable at high
temperatures.
Stability:
Insensitive
to atmospheric agents.Â
Â
Application:
Friction materials, filtration materials, insulation materials, painting, rubber, refractories, chemical and so on.

Expanded vermiculite applied to roof, could expect good response of avoid high temperature, It is cool in summer and warm in winter. Tall building partition with Vermiculite brick construction, have effect of noise-proof, moisture-proof, mainwhile reducing load building.
