11584040 · 2023-02-21 ·

The present invention relates to a manufacturing method of a natural fiber composite material for injection molding using a reduced nozzle heating jig, and particularly, to a manufacturing method of a natural fiber composite material for injection molding using a reduced nozzle heating jig, which is configured to include: combining natural fibers and synthetic fibers (S1); heat-pressing the combined ply yarn while passing through a reduced nozzle heating jig 100 and melting and pressing the synthetic fibers and fusing the synthetic fibers to the natural fibers (S2); and palletizing the mixed ply yarn (S3).

Molded parts with thermoplastic cellulose biopolymer compositions having oriented fibers for medical devices and implants

A longitudinal extending body with oriented fibers comprised of an organic compound, preferably cellulose fibers, with a hydrophilic and hydrophobic polymer having absorbable and non res sorbable qualities in the body, with an internal construction to promote cell growth. The longitudinal body has at least one wall having oriented fiber to include cellulose fiber extending the length of said body. This extending body has a surface that is smooth to the touch for additional processing methods such as machining, compression molding and 3 D printing.

Single-component polysiloxane non-skid / non-slip coatings

Disclosed is a composition having: an organosilane polymer, a polyamide polymer; and an abrasive aggregate. The organosilane is made by: reacting an amino-functional alkoxysilane with one or more polyisocyanates to form one or more adducts having an unreacted isocyanate group; and reacting the adducts with one or more polyfunctional amino- and/or hydroxyl compounds so that the polymer contains no unreacted isocyanate groups. The polyfunctional amino- and/or hydroxyl compound has a cycloaliphatic group or an aromatic group. The composition can be used to make a single-component polysiloxane non-skid/non-slip coating that is applied by rolling, spraying, or troweling and cures with atmospheric moisture.
