POLYPROPYLENE POLYMERS FOR POWDER BED FUSION BASED ADDITIVE MANUFACTURING
The invention relates to a sinterable polymer composition, comprising: a random copolymer of propylene and an olefinic comonomer, containing about 2 to 10 wt % olefinic comonomer content, relative to 100 wt % of the random copolymer. The sinterable polymer composition may also contain at least one of a clarifier and a nucleator, and/or at least one additive selected from the group consisting of a primary antioxidant, a secondary antioxidant, an acid scavenger, a peroxide, an enhanced IR energy absorber, a long-term heat agent, and a polyolefin elastomer. The sinterable polymer composition has a melt flow rate from about 1 to 150 g/10 min (230° C./2.16 kg), measured according to ASTM D 1238; a crystallization temperature, Tc, from about 105 to 150° C.; and a xylene solubles content, XS, from about 3% to 40%.
OPTICAL SHEET AND OPTICAL COMPONENT
An optical sheet 10 of the present invention includes a laminate including a polarizing layer 4 containing at least one kind of a light absorbing agent and having a polarizing function, and a protective layer 1 laminated on the polarizing layer 4, in which in the polarizing layer 4, a value of a* is 0 or more and 30 or less and a value of b* is 0 or more and 30 or less in an L*a*b* color system defined by JIS Z 8781-4, and in the optical sheet 10, a size of a Q Blue value defined by Australian Standard Australia/New Zealand Standard 1067-2016 is 0.70 or more. Thus, even when the optical sheet is toned to brown, blue light can be distinguished with excellent distinguishability.
Coextruded Polyethylene Pipe and Methods of Making and Using Same
A pipe having an inner layer and an outer layer. The inner layer includes a first material having a first hydrostatic design basis (HDB), and the outer layer is coextruded with the inner layer and includes a second material having a second HDB. The second HDB is greater than or equal to the first HDB, and the first HDB and the second HDB are as specified in ASTM Test Method D2387. Also provided re methods of making and using the pipe.
METHOD FOR DRIPLESS LIQUID COLOR DELIVERY USING A DRIPLESS LIQUID COLOR FEED THROAT ADAPTOR
Apparatus and methods for converting resin into colored finished or semi-finished plastic parts include a process machine having a barrel, a rotatable screw inside the barrel, and a color feed conduit assembly extending into the barrel for passage of liquid color through the color feed conduit assembly into proximity with the screw.
MULTICOLOR WOOD-PLASTIC PROFILE, MANUFACTURING METHOD THEREFOR AND WOOD-PLASTIC BOARD
A multicolor wood-plastic profile is made of a color master batch and a wood-plastic base material. The ratio λ of the tensile elastic modulus (Et) of said color master batch to that of said base material is 0.26-1.47. A manufacturing method for the multicolor wood-plastic profile includes mixing and melt extruding the color master batch and the base material. A wood-plastic board, including the multicolor wood-plastic profile. The outer surface and the interior of the multicolor wood-plastic profile have two or more colors, presenting a mixed gradual texture similar to natural wood.
Shaping system, and shaping apparatus
Disclosed is a shaping system for shaping a three-dimensional object, which includes a slice data generation step that generates slice data and a shaping execution step that shapes the three-dimensional object by a shaping apparatus based on the slice data. The shaping apparatus shapes the three-dimensional object using inkjet heads. The slice data generation step has a color cross-section data generation step that generates color cross-section data showing at least a cross-sectional shape of the three-dimensional object and a color at each position, a plate division data generation step that generates plate division cross-section data in which the color cross-section data is color-separated for each color of the material, and a plate division cross-section data change step that changes at least some plate division cross-section data. The slice data is generated based on the plate division cross-section data changed in the plate division cross-section data change step.
Method of making a multilayered elastomeric article
Elastomeric articles, such as gloves, made from more than one layer, are provided. The gloves can include a first (grip side) layer in which a first colorant is compounded or integrated and a second (donning side) layer in which a second colorant is compounded or integrated. Alternatively, the gloves can include a translucent first layer and a second layer in which a colorant is compounded or integrated. Either arrangement can enable a breach of the first layer to be more easily detected, either due to the high level of contrast between the first layer and the second when a first colorant and a second colorant are utilized, or due to the translucence of the first layer as compared to the donning side layer, where the intensity of the second layer is increased upon a breach of the translucent first layer.
Inks for 3D printing having low print through depth
In one aspect, inks for use with a three-dimensional (3D) printing system are described herein. In some embodiments, an ink described herein comprises up to 80 wt. % oligomeric curable material; up to 80 wt. % monomeric curable material; up to 10 wt. % photoinitiator; up to 1 wt. % non-curable absorber material; and up to 10 wt. % one or more additional components, based on the total weight of the ink, and wherein the total amount of the foregoing components is equal to 100 wt. %. Additionally, the photoinitiator is operable to initiate curing of the oligomeric curable material and/or the monomeric curable material when the photoinitiator is exposed to incident curing radiation having a peak wavelength λ. Moreover, the ink has a penetration depth (D.sub.p), a critical energy (E.sub.c), and a print through depth (D.sub.PT) at the wavelength λ of less than or equal to 2×D.sub.p.
