Patent number: 7781510Abstract: This invention pertains to highly filled polymer compositions comprising a low molecular weight ethylene and/or alpha olefin homopolymers and copolymers, or blends therefrom, filled with high concentrations of fillers or additives. Examples of such fillers or additives include fire retardants, talc, ceramic manufacturing agents, color concentrates, crosslinking agents, and blowing agents. Because of the low crystallinity (and therefore high percentage of amorphous phase) and low viscosities of the base polymers, highly processable compositions can be formed containing even if containing relatively high loadings of fillers or additives. Such highly filled compositions are thus ideally suited as concentrates or masterbatch formulations for a variety of different compounding applications.Type: GrantFiled: November 27, 2007Date of Patent: August 24, 2010Assignee: Dow Global Technologies Inc.Inventors: Selim Yalvac, Brad M.

Patent number: 7482402Abstract: The present invention is directed generally to fiber reinforced polypropylene compositions, and the beneficial mechanical properties imparted by such compositions. The fiber reinforced polypropylene compositions include at least 25 wt % polypropylene based polymer, from 5 to 60 wt % organic fiber, and from 0 to 60 wt % inorganic filler. Lubricant may also be optionally incorporated into the composition. Articles molded from these fiber reinforced polypropylene compositions have a flexural modulus of at least 300,000 psi, and exhibit ductility during instrumented impact testing. The fiber reinforced polypropylene compositions of the present invention are particularly suitable for making molded articles including, but not limited to household appliances, automotive parts, and boat hulls.Type: GrantFiled: December 13, 2005Date of Patent: January 27, 2009Assignee: Exxonmobil Research and Engineering CompanyInventors: Arnold Lustiger, Jeffrey Valentage, Walter T.

Publication number: 20080293866Abstract: A composite material comprises a particulate material generated as a waste by-product of an industrial process, and a binder for binding the particulate material into a uniform mass. The particulate material and binder are combined in preselected proportions and compressed to form a counterweight having a preselected density and a fixed configuration. A counterweight is manufactured by selecting a first proportion of a particulate material generated as a waste by-product of an industrial process, selecting a second proportion of a binder for binding the particulate material into a uniform mass, combining the first proportion of the particulate material with the second proportion of the binder into a uniform mass, forming the counterweight from the uniform mass, and incorporating the counterweight into a finished product.Type: ApplicationFiled: April 13, 2007Publication date: November 27, 2008Applicant: INNOTECInventors: Lucas B.
