  • Publication number: 20210353821
    Abstract: The filament and suture products disclosed are to be implanted in the body, having non re sorbable ingredients with absorbent qualities to disperse an antibiotic and strong enough to hold tissue securely but flexible enough to be printed or knotted. The products are biocompatible and consist of two dissimilar polymers having unmelted cellulose fiber. These dissimilar polymers and the unmelted fibers are densified by compression and the removal of moisture having fiber orientation and alignment, showing low levels of radiopacity. These products will have radiopacity in household units (HU) ranging from ?200 to 200 HU and produce meshes, bone grafts, scaffolds or wound care products where bone bridging can be observed.

  • Publication number: 20180147327
    Abstract: A molded article consisting of an organic compound, preferably cellulose fibers having a glass transition point above 200 C and melt blended with thermoplastic polymers of different melt temperatures, whereby, a 3 or 4 Dimensional printer that may consist of an additional 5 or 6 axis, has cellulose fiber particles that are layered and compressible in a semi solid state. These layers having non oriented cellulose fiber particles will help produce a buoyant molded article with a surface texture that can absorb moisture and attract gases for coatings.

  • Patent number: 9109118
    Abstract: A cellulosic inclusion-thermoplastic composition that includes cellulosic inclusions and a thermoplastic polyolefin that forms a matrix in which the cellulosic inclusions are dispersed. A maleated polymer and a polar thermoplastic polymer resin of a polyamide or polyester are provided to improve adhesion between the cellulosic inclusions and the thermoplastic polyolefin. The polar thermoplastic polymer resin is characterized by a melting temperature greater than that of the thermoplastic polyolefin. The composition as provided has increased break tensile strength relative to a composition devoid of the polar thermoplastic polymer resin but otherwise is unchanged. The break tensile is measured at 23° Celsius and at an elongation rate of 50 millimeters per minute.

  • Patent number: 7994241
    Abstract: A crystalline polyamide 6 in a compounding extrusion process to make wood flour-polyolefin composite. The wood plastic composite pellet and can be post-blended with reinforced polyolefin pellets in an injection molding step to produce hybrid fibrous composites. The resulting compatibilization in the hybrid fibrous composites gives molded parts having enhanced mechanical properties at greatly reduced temperatures. There is wide variety of molded parts that can be made by varying the blend ratio of the wood plastic compounded product with or without and glass fiber reinforced pellets in the injection molding step.
