PROPERTIES

Low Density

Excellent Fire Resistance

Shape : ECA has a spherical shape resulting from the pelletizing technique used. This leads to minimal settlement after placing.

Decomposability : ECA has strong chemical resistance against acidic and alkaline substance, which helps to maintain the pH value of 7-9.

Compressive : ECA has very high compressive strength.

PROPERTIES

Sound Insulation : ECA has been proved to one of the best sound insulator. An ECA block of width 20cm has capacity of insulating sound up to 45db to 46db respectively.

Environmentally Friendly : ECA generates no pollutants or hazardous wastes.

Excellent Thermal Insulation

Low Coefficient Of Thermal Expansion
