The invention relates to an endless vehicular rubber track. The invention particularly relates to such track having hard rubber guide lugs with a softer guide support layer. It is to be appreciated that such guide lugs may also be positively driven drive lugs. The invention further relates to a vehicle having such track.

Endless rubber track having guide lugs with guide lug support layer, and vehicle containing such track

The invention relates to an endless vehicular rubber track designed for extreme cold temperature working environment. The invention particularly relates to such track having a combination of tread, supporting carcass and guide lug components of rubber compositions intended for such purpose.

Cold environment endless rubber track and vehicle containing such track

The invention relates to a two part endless vehicular rubber track comprised of a polyurethane based tread component and a rubber carcass component. In one aspect, the tread component may be comprised of a sulfur curable polyurethane or blend of sulfur curable polyurethane and sulfur curable elastomer. The invention includes a vehicle containing such track.

Endless two part rubber track comprised of polyurethane based tread component and rubber carcass component and vehicle containing such track

The invention relates to an endless vehicular rubber track. The invention particularly relates to such track having a ground-contacting tread component of a rubber composition.

Endless rubber track and vehicle containing such track

The present invention relates to a rubber article having a surface construction designed for abrasion resistance wherein the surface comprises a series of rubber layers parallel to each other and in a density of from at least 200 layers per 25.4 millimeters as measured along the surface area of the article and in a direction perpendicular to each layer.

Rubber article having a surface design for high abrasion resistance

A rubber tire is provided which contains an electrically oriented composite within a rubber composition component of the tire, wherein said composite is composed of at least two electrically conductive metal elements in close proximity to each other and an electrically conductive rubber composition which is in contact with and electrically connects said metal elements together. The invention also contemplates an electrically resistive rubber composition within said tire rubber component which is juxtapositioned to at least a portion of said electrically conductive rubber composition and to at least a portion of at least one of said electrically conductive metal elements.

Tire with electrically oriented composite

A sulfur cured rubber composition composed of selected natural rubber and carbon black for sensing pressure with reference to applied sinusoidal electrical energy.

Frequency sensitive conductive rubber composition

A method of preparing a composite of polyurethane bonded to the surface of a cured rubber substrate and the resulting composite. The method requires the rubber substrate to contain an hydroxyl terminated polybutadiene polyol. The method is practiced by first applying to a cleaned, cured rubber surface containing the polybutadiene polyol a coating of cyanuric acid followed by an additional coating of a phenol formaldehyde resin and then applying a liquid polyurethane reaction mixture which is cured to form the resultant composite. The invention is particularly directed to the preparation of a tire comprised of a polyurethane carcass applied to a cured rubber tread and to a tire comprised of a polyurethane tread applied to a cured rubber carcass.

Polyurethane bonded to cured rubber containing a diene polyol

A substantially solid industrial polyurethane tire/wheel assembly where said polyurethane is prepared by reacting (A) a curative of 1,3-propane diol with a prepolymer of diphenylmethane-4,4'-diisocyanate and a polymeric polyol or (B) a curative complex of 4,4'-methylene dianiline with a prepolymer of a diisocyanate selected from diphenylmethane-4,4'-diisocyanate and toluene diisocyanate with a polymeric polyether polyol. It is an important feature of this invention that the selection of reactants involved, for the dianiline complex, a partial substitution of the polyether polyol with a polyether-ester polyol.

Solid polyurethane tire/wheel assembly

A mold release agent comprising metallic soaps of the fatty acids in combination with 0.03 to one percent of a polyurethane catalyst selected from secondary and tertiary amines and organic tin compounds.

Mold release agent

A polyurethane reaction mixture mold release comprising 1 to 5 percent by weight of a sodium or potassium soap of a carboxylic acid of 11 to 22 carbons in a diluent of alcohol or water, the mold release being applied to a mold, then addition of a polyurethane reaction mixture to form a shaped polyurethane of the microcellular type, stripping the shaped article from the mold, flushing with water at 40.degree. to 95.degree.C., drying, applying a paint coat of 3 to 10 mils over the polyurethane article to obtain a polyurethane decorative article having a paint coat resistant to peeling.
