Method of manufacturing a filament formed reinforcement member and a run flat tire support therewith
Patent number: 6989065Abstract: The present invention provides a unitary run flat tire (RFT) reinforcement using filament material that is formed into a relatively rigid shape. The reinforcement is insertable into a mold for an RFT support and can maintain the needed structural rigidity for such insertion. Further, the invention provides an RFT support that is molded and includes the RFT reinforcement. The invention also provides a wheel assembly including a tire, a rim, and an RFT support between the rim and the tire, where the support includes the RFT reinforcement. The RFT support can have a colored indicator formed or subsequently applied thereto to indicate one or more attributes of the support.Type: GrantFiled: September 6, 2001Date of Patent: January 24, 2006Assignee: The Dow Chemical CompanyInventors: Rick L.

Patent number: 6399206Abstract: Polyurethane/polyurea polymers can be electrostatically painted without first being coated with a conductive primer. Disclosed is an improvement in a process for electrostatically painting polyurethane/polyurea polymers, the improvement being to prepare the polymer from a formulation including a non-volatile metal salt conductivity inducing material. The polymers of the present invention can be charged with sufficient charge density to permit efficient paint transfer to the polymer surface. Also disclosed is a composition of at least two adjacent layers, one layer being an outer layer of electrostatically applied paint, and the other an inner layer of polyurethane/polyurea polymer.Type: GrantFiled: September 24, 1996Date of Patent: June 4, 2002Assignee: The Dow Chemical CompanyInventors: Robert Carswell, Martin C. Cornell, Cynthia K. Groseth, James R. Porter, Ralph D. Priester, Jr., Ricky L. Tabor, Melissa J. Zawisza

Disclosed is a process for electrostatically painting polyurethane/polyurea polymers, the process having a step of including a non-volatile metal salt conductivity inducing material. The conductivity of the polymers of the present invention can allow them to be charged with sufficient charge density to permit efficient paint transfer to the polymer surface. Also disclosed is a composition of at least two adjacent layers, one layer being an outer layer of electrostatically applied paint, and the other an inner layer of polyurethane/polyurea polymer.Type: GrantFiled: May 13, 1997Date of Patent: November 3, 1998Assignee: The Dow Chemical CompanyInventors: Robert Carswell, Marty C.

Patent number: 5106884Abstract: The invention includes a process for preparing a flexible, water-blown polyurea foam by reacting a reaction mixture containing at least one polyisocyanate component and an active hydrogen component, wherein active hydrogen compounds of relatively high equivalent weight have an average of about 1.5 to about 4 active hydrogen-containing groups per molecule, of which active hydrogen-containing groups: an average of (a) from about 5 to about 60 percent are primary aliphatic amine groups or (b) at least about 25 percent are primary aromatic, secondary aliphatic, Lewis acid-blocked primary or secondary aliphatic or aromatic amine groups or mixtures of such groups. An amount of at least one alkali metal halide salt effective to increase load bearing strength of the foam is incorporated into the reaction mixture. Differing amounts of alkali metal halide salts are suitably incorporated into different areas of the foam to produce areas having differing load bearing strengths.Type: GrantFiled: October 28, 1988Date of Patent: April 21, 1992Assignee: The Dow Chemical CompanyInventors: Robert B.

Patent number: 4980388Abstract: A polyurea foam is formed from a reaction mixture comprising at least one polyisocyanate component and an active hydrogen component, wherein active hydrogen compounds of relatively high equivalent weight have an average of about 1.5 to about 10 active hydrogen-containing groups per molecule, of which active hydrogen-containing groups: an average of (a) from about 5 to about 60 percent are primary or secondary aliphatic amine groups or (b) at least about 25 percent are primary aromatic, Lewis acid-blocked primary aliphatic, secondary aliphatic or aromatic amine groups or mixtures thereof. Carbon dioxide is adducted to said active hydrogen component. The adduct releases carbon dioxide to blow the foam.Type: GrantFiled: October 17, 1988Date of Patent: December 25, 1990Assignee: The Dow Chemical CompanyInventors: Ronald M. Herrington, Robert B.

Patent number: 4845133Abstract: Flexible polyurethane foams are prepared by reacting a polyisocyanate with certain amine-terminated compounds. The amine terminated compounds are characterized in having at least 30 percent of their active hydrogen-containing groups in the form of primary aromatic, Lewis acid-blocked primary aliphatic and/or secondary aromatic or aliphatic amine groups. The resulting foams exhibit excellent physical properties, even in the absence of a cross-linker compound.Type: GrantFiled: March 21, 1988Date of Patent: July 4, 1989Assignee: The Dow Chemical CompanyInventors: Ralph D.
