Exfoliated Vermiculite

Exfoliated vermiculite is very porous, lightweight, loose material. Vermiculite has thermal insulating and sound insulating properties, as well as high absorbent properties - can absorb liquids up to 530% of its own weight.

Vermiculite is chemically inert, neutral to the action of alkalis and acids. It is environmentally friendly and sterile material. It is non-toxic and does not contain heavy metals.

It is not susceptible to rot and degradation by microorganisms. It is an unfavorable environment for insects and rodents.

PACKAGING

Exfoliated vermiculite is packed in 100 L polypropylene bags or 100 L corrugated paper boxes.

 

SHELF LIFE

Shelf life of vermiculite concentrate is not limited.

 

STORAGE

  • Products should be stored in a packed form in covered dry storage facilities in conditions that do not allow its moisture and dirt.
  • Stacking height of exfoliated vermiculite in 100 L polypropylene bags should not exceed 1.5 m.
  • Stacking height of exfoliated vermiculite in 100 L corrugated paper boxes should not exceed 5 m.

 

TRANSPORTATION

  • Transporting leads to crushing the grades of exfoliated vermiculite and decrease in its volume up to 15% depending on the distance and conditions of transportation.
  • During transportation, the humidity of vermiculite may change, but not more than 3% of specified characteristics.
  • Shipment is made by any means of transport on request.
