摘要:
Disclosed is an electrically conductive thermoplastic polymer composition comprising a thermoplastic polymer, an impact modifier and a combination of metal fibers and metal-coated fibers, structures made therefrom, and a process to make said compositions and structures.
摘要:
The present invention thus provides a plastic part with a surface area of a semi-rigid sheet material such as metal, wood or wood-based paper product and a novel process where the sheet material edges are covered with a second plastic component that adheres both to the sheet material and to the first plastic material. A first plastic substrate component is prepared with an adhered sheet material surface area and then the edges of the sheet material are overlapped by a second molded-on, plastic edge-covering component. A preferred sheet material laminate structure is also provided with a backing layer that protects an interior adhesive layer. The second molded-on edge-covering component covers the sheet material edge to provide an aesthetically pleasing surface. This construction produces a more durable sheet material edge covering and eliminates the tendency of the sheet material to peel off the molded part during use.

An electrically conductive article including a substrate and at least one electrically conductive layer disposed on the substrate. The conductive layer may include a thermoplastic resin and from about 1 to 30 weight percent of at least one conductive additive based on a total weight of the thermoplastic resin and the at least one conductive additive. The conductive article may have a surface resistance between 0.001 to 20Ω at a test distance of 2.54 cm (1 inch).

摘要:
The present invention provides thin injection molded plastic articles with an attractive, surface area of at least two different materials, such as leather, fabric, wood, metal or other semi-rigid surface material. These molded articles have desired combinations of thin dimensions, aesthetics and/or durability with the true feel of the real materials. The molded plastic articles thus have a plastic substrate component with a front decorative surface having at least two decorative surface areas of layers of different first and second materials having adjacent and connecting surface areas that are generally coplanar or continuous, including at the border line where the two surface layer materials meet. Relative to the front surface, at least a portion of the first material is located on top of and overlaps at least a portion of the second. In the process embodiment two surface material pieces are located in a mold cavity, the two materials together being located so as to each provide a surface area on the front side of the molded part. Optionally there is an adhesive and/or backing material on the back or non-decorative side of one or both surface material pieces. A molding plastic is injected into the mold that contacts and adheres to the back side of the surface material(s) and provides a molded on plastic substrate component. While the molding plastic is sufficiently fluid, pressure is applied to the cavity, preferably in an injection molding process, sufficient to compress and/or form the two different surface materials into a substantially coplanar or continuous surface and press the thicker overlapped area to a necessary depth into the plastic substrate component.
