Northfil

Company Description

Northfil operate a large mill and 2 mines producing a serpentine consisting of antigorite, a hydrous magnesium silicate. This material has been found to be a very useful filler/additive in the manufacture of tires and PVC plastic as it solves several problems associated with other additives. Some have also used it as an asbestos substitute as it has similar properties.We are capable of exporting large amounts of this material 1000-80,000 ton orders and currently have samples and a sales agent in Guangzhou. We also have started mining vermiculite and are willing to export custom orders (www.northfil.com). We are also always available to do custom milling or toll grinding.
