Abstract: It has been unexpected found that the fluid resistance of hoses can be greatly enhanced by adding a chlorinated paraffin to a chlorinated polyethylene elastomer or a chlorosulfonated polyethylene elastomer which is used as the tubular inner core layer of the hose. Hoses made using this approach offer the advantage of having improved resistance to modern automotive fluids, provide a longer service life, and better reliability without compromising flexural characteristics or burst strength. Such hoses are comprised of (1) an elastomeric tubular inner core layer defining a lumen, (2) a friction layer, and (3) an elastomeric cover, wherein the elastomeric tubular inner core layer is comprised of (i) a chlorinated elastomer selected from the group consisting of epichlorohydrin, polychloroprene, chlorinated polyethylene and chlorosulfonated polyethylene, (ii) 1 phr to 50 phr of a chlorinated paraffin, and (iii) 30 phr to 120 phr of carbon black.

Abstract: The invention relates to a tire having a tread of a cured rubber composition which contains dual silica moieties in a sense of containing both hydrophilic precipitated silica and in situ hydrophobated precipitated silica.

Abstract: The present invention is based on the unexpected discovery that the fluid resistance of hoses can be greatly enhanced by adding a chlorinated paraffin to a chlorinated polyethylene elastomer or a chlorosulfonated polyethylene elastomer which is used as the tubular inner core layer of the hose. Hoses made using this approach offer the advantage of having improved resistance to modern automotive fluids, including power steering fluid, transmission fluid, and the like, without compromising flexural characteristics or burst strength. Accordingly, the hoses of this invention provide a longer service life and better reliability then hoses made utilizing conventional technology.

Abstract: The present invention is directed towards speckled tire treads for tires. Specifically, the speckled tire tread includes a primary tread compound that serves as a matrix in which is distributed discrete particles of one or more secondary tread compounds, at least one of the compounds is a different color than the other tread compound(s) so as to be visually distinguishable. For example, the primary tread compound may include carbon black pigment and be black in color while the secondary tread compound can include one or more pigments to provide the particles with non-black color. Thus, the colored particles have a visually distinguishable color from that of the primary tread composition. Additionally, at least a portion of the particles may be situated for viewing on a running surface of the tire tread so that a subject can visually distinguish between the compounds, and such observed compounds may provide a different tire performance characteristic(s).
