SILICAGEL

ADsorbent bags

We guarantee an environment free of moisture and odors since 1986

About

Over the years we have endeavored to provide good service to our customers and deliver a quality product.

History

Silicagel is a family firm established in 1986. From the beginning it works on the adsorbent chemical products field. The final products are adsorbing bags used to obtain an atmosphere free of humidity and odours.

Service

From the beginning the firm has prioritised the realization of customised final products considering the needs of each client, and speeding up the production process and the delivering of the product.

Product

The market product is wide, with various and specific goals for each specific case.

Products

Products used as raw materials in the field of adsorbents are silica gel, activated alumina and activated carbon.

Filling process

The filling process is performed with continuous volumetric filling equipment fed with hot-melt film and raw materials to finally obtain the adsorbing bag.

Final product

The final product consists of the adsorbent bags from raw materials (silicagel, activated alumina and activated carbon).The versatility and quality of the final product is due to the extend range of weights (12 to 500 grams) and formats available. The flexibility and the customised product is the key of the service offered.

Market

The final product market is focused mainly on chemical and pharmaceutical industries, but also on all those companies that require adsorbing bags for their activity where a free humidity or odour atmosphere is required.

We can also offer service and assessment for specific applications in the general field of adsorbent products.
