  • Patent number: 10472440
    Abstract: Toughened polyolefins and methods used to produce toughened polyolefins in presence of a bio-filler. These materials can substitute traditional thermoplastic polyolefins known as TPOs or mineral filled TPOs. Exemplary compositions include a phase based on ?-olefin elastomers and the use of biobased fillers. The bio-based filler used, can be a material rich in elemental carbon content. The use of additives is of regular usage for these compositions as they may be related to coupling agents, UV absorbers, light stabilizers, antioxidants, and so forth. These composition offer a remarkable lower density compared to traditional TPOs compositions altogether with bio-based value-performance addition.

  • Patent number: 7649036
    Abstract: Blended compositions and methods for the production of thermoset compositions of soy meal, which has been treated to remove non-thermoplastic materials associated with soy beans, and natural rubber. Also provided is a method for the preparation of a prepared granular soy meal by blowing a gas through a stream of granular natural soy meal to remove hulls and cellulose fiber materials which are lighter than the granular soy meal to provide the prepared granular soy meal for the compositions. The compositions are elastic and can be used in place of rubber bands and the like.

  • Patent number: 7582241
    Abstract: A thermoplastic polymer composition reinforced with fibers such as cellulose or other fillers, particularly from natural sources, and a process for manufacturing the composition are disclosed. The polymer is extruded with a salt which reduces the melting point and pelletized. The pellets are then extruded again with the filler. The composition with the filler can then be melted at the reduced melting temperature to manufacture an article.
