Patents by Inventor Jing-Han (Helen) WANG

Jing-Han (Helen) WANG has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20250042142
    Abstract: The invention relates to a multi-layer paneling structure having a high gloss cap and second layer of high impact resistance thermoplastic polymer or composites for exterior and interior paneling applications where chemical resistance and/or scratch resistance is desired. The invention also relates to a high gloss, multi-layer panel that can easily be repaired, once marred, to return the surface gloss to at least 90% of the original surface gloss. The invention further relates to articles made with the multi-layer paneling structure of the invention. The multi-layer structure can be used alone, or can be very thin and used as a replacement for an undercoating and coating on an article, such as a metal car part.

  • Publication number: 20240343900
    Abstract: An impact modified hydrophobic acrylic composition includes (a) a hydrophobic acrylic copolymer having: (i) monomer units chosen from tert-butyl cyclohexyl methacrylate, 3,3,5-trimethylcyclohexyl(meth)acrylate, and a mixture thereof; (ii) methyl methacrylate monomer units; and (iii) optionally other monomer units copolymerizable with methyl methacrylate; (b) optionally, other (meth)acrylic copolymers; (c) one or more core-shell impact modifiers, wherein the core-shell impact modifiers have a volume average particle size of from 70 to 350 nm, wherein the melt flow rate of the impact modified hydrophobic acrylic composition is greater than 1.0/10 minutes at 230° C. under 3.8 kg; and wherein the notched Izod impact strength of the impact modified hydrophobic acrylic composition is greater than 4.5 kJ/m2.

  • Patent number: 12077663
    Abstract: Compounds that can be produced by a ring-opening reaction of epoxidized alkanes or epoxidized fatty acid esters having a molecular weight greater than 200 grams per mole are blended with polar polymers to improve the gloss of the polar polymers. These compounds include at least one polar functional group and are blended with polar polymers, or blends comprising at least one polar polymer, in order to improve the gloss of these polymers, such that they have suitable gloss right out of the manufacturing operation without the need for further painting or lamination steps. These compounds may also improve the impact strength of the polar polymers. Also disclosed are composite structures wherein an outer cap layer is made from the polar polymer blended with the gloss improving additive.

  • Publication number: 20220161496
    Abstract: The invention relates a material extrusion additive manufacturing method for producing a clear, internally transparent part composed of amorphous thermoplastic polymer layers at least 0.1 mm thick. The invention also relates to internally clear parts made by the method, having an internal haze of less than 25%, less than 15%, less than 10% and even less than 5%. The method creates a printed dot or line of amorphous thermoplastic polymer that remains at a high internal temperature for a long enough period of time to allow the polymer chains in each layer to be mobile and fluid, permitting sufficient inter-layer chain entanglements to reduce and eliminate layer lines. With a nearly 100% dense final part, voids are eliminated. The resultant printed article has a very high internal clarity, and can have a haze of less than 5%.
