It is low in contraction, but high in plasticity.
It dissolves in hedrochloric acid.
It is insulating and salt resistant, etc.

Sepiolite series products

It is widly used:

_ Polymers and Elastomers: The use of sepiolite fillers

improve processing, dimensional stability, mechanical

strength and thermal resistance.

_ Roof Panels: Sepiolite improves binding of the

components while increasing the fire resistance.

_ Construction additives: Sepiolite provides thixotropy

making for easier application, preventing sagging and

providing a better quality finish in mortars, plasters and

concrete. It is also used as a processing aid in the

manufacture of fibre-reinforced cement products.

_ Bitumens: Sepiolite allows controlling the rheological

properties in heat application systems, improving fire

resistance. It also improves the stability and the

application in emulsions and asphalt in solvent products.

_ Rheological additives for aqueous systems: Sepiolite

provides stability, pseudoplasticity and thixotropy in

different applications as paints, adhesives, mastics and

sealants.

_ Rheological additives for organic systems: Organically

modified sepiolite allows controlling the rheological

behaviour of different solvent-based systems as paints,

greases, resins and inks enhancing their stability under a

wide temperature range and making for easier application.
