A leather substrate formed from waste leather and its method of production, particularly a leather substrate made up substantially of a collagen fibril matrix.

High-strength and tear-resistant leather materials and methods of manufacture

High strength leather material

Dispersion processing aids for the formation of a leather material

Disclosed are flocced mineral materials which may be utilized to prepare high temperature resistant, water resistant articles. These materials are prepared by utilizing, as a starting material, a gellable layered swelled silicate that has an average charge per structural unit that ranges from about -0.4 to -1 and which contains interstitial cations which promote swelling with a source of at least one species of multiamine derived cations.

Layered silicates and water-resistant articles made therefrom

Sheets and laminated composites are described which are prepared with epoxy and flocculated vermiculite and mica dispersions. Processes and procedures are also described to obtain film and sheet materials from the flocculated silicate and epoxy dispersions.

Multi-ply composites and sheets of epoxy and flocced 2:1 layered

Chemically prepared mica and vermiculite materials are described along with the method for preparing them. The mica and vermiculite has dimethylacetamide-lithium chelation complexes at interlayer cationic sites. These materials can be made into suspensions and flocculated.

Dimethylacetamide mica and vermiculite suspensions

Disclosed are flocced mineral materials which may be utilized to prepare high temperature resistant, water resistant articles. These materials are prepared by utilizing, as a starting material, a gellable layered swelled silicate that has an average charge per structural unit that ranges from about -0.4 to -1 and which contains interstitial cations which promote swelling with a source of at least one species of multi-amine derived cations.

Flocced 2:1 layered silicates and water-resistant articles made therefrom

An aqueous suspension of sheet silicate and the method of making the same are disclosed. The suspension is produced by treating crystals of 2:1 layer sheet silicates with a solution containing a water soluble salt of a cation of a secondary, tertiary or quaternary alkyl ammonium compound and thereafter dispersing the vermiculite crystals.

Suspensions of sheet silicate materials and products made therefrom

Two:One layered silicate flocs with homogeneously intermixed polymers and a method for the compositions's preparation is described. Preferred embodiment include co-flocculated homogeneously intermixed polymer and 2:1 layered silicate. The materials are prepared by contacting a co-dispersion of polymer and silicate with a cationic flocculant.

Paper, paper products, films composites and other silicate-polymer,

Disclosed are compositions of flocced mineral materials combined with fibers and/or binders. These compositions may be utilized to prepare high temperature resistant, water resistant articles. These materials are prepared by utilizing, as a starting material, a gellable layered swelled silicate that has an average charge per structural unit that ranges from about -0.5 to -1 and which contains interstitial cations which promote swelling with a source of at least one species of an exchange cation that is derived from guanidine or compounds closely related thereto.
