摘要:
The invention provides novel pellets having high fluidity in a hopper of an extruder and capable of forming a coating layer having good wire diameter stability and capacitance stability even when used for rapid molding of electric wire coating. The pellets contain a fluororesin. Each of the pellets, placed on a horizontal surface, has a substantially circular outline or a substantially elliptic outline and has a major axis D 1 of 3.1 mm or shorter and a minor axis D 2 of 3.1 mm or shorter when observed in the direction normal to the horizontal surface. Each pellet satisfies the following formula (1): (D 1 + D 2 )/2L = 1.8 to 2.6, wherein D 1 represents the major axis, D 2 represents the minor axis, and L represents the height from the horizontal surface to the highest point of the pellet.

Provided is a molded resin strand configured so that interlayer fusion of a shaped object can be improved and mechanical aptitude (specifically, stiffness) in a 3D printer can be more improved even in a case where an inorganic filler such as carbon fibers is mixed. The molded resin strand contains thermoplastic resin, an inorganic filler, and α-olefin elastomer. The thermoplastic resin is polypropylene, for example. The inorganic filler is carbon fibers, for example. The α-olefin elastomer is ethylene-α-olefin copolymer, for example. The molded resin strand of the present invention is used for a 3D printer employing a fused deposition modeling method.

Provided is a resin panel without warpage, in which weight reduction and high rigidity of the resin panel have been promoted. The resin panel (1) according to an aspect of the present invention is a resin panel (1) having a back wall (3), a front wall (2) facing the back wall (3) with a gap therebetween, and ribs (3a) formed by having portions of the back wall (3) depressed toward the front wall (2) and welded to the inner surface of the front wall (2), characterized in that the back wall (3), the front wall (2) and the ribs (3a) are configured by mold-clamping, in a split mold, a first molten resin in a molten state and incorporating a plate-shaped filler, which constitutes the back wall (3), and a second molten resin in a molten state and incorporating a plate-shaped filler, which constitutes the front wall (2), the first molten resin and the second molten resin having been extruded and flowed out from an extrusion apparatus, and the longitudinal direction (3a1) of the ribs (3a) is non-parallel to the direction of flow of the first molten resin and the second molten resin.

The present invention relates to 3D printer inputs including filaments comprising separated layers or sections. These inputs particularly including filaments may be prepared by coextrusion, microlayer coextrusion or multicomponent/fractal coextrusion. These inputs and specifically filaments enable layering or combining different materials simultaneously through one or more nozzles during the so-called 3D printing process. These techniques facilitate smaller layer sizes (milli, micro, and nano) different layer configurations as well as the potential to incorporate materials that would otherwise not be usable in standard 3D printer methods.

A vessel is configured to hold a product in an interior region formed in the vessel. The vessel includes an inner layer arranged to define the interior region and an outer layer. The vessel is formed using a blow-molding process in which a multiple layer parison is blow molded to form the vessel. The multiple layer parison is formed in an extrusion process in which a number of extruders are arranged to co-extrude associated inner and outer parisons to establish the multiple layer parison.

Provided is molded foam having no hollow space caused in a plate-shaped portion. Molded foam (1) of the present invention is molded foam (1) including a tube body (X1) and a plate-shaped portion (Y1) joined to the outer side of the tube body (X1). The expansion ratio of the molded foam (1) is lower than two, and a value of a thickness B/a thickness A as a relationship between the thickness A of the tube body (X1) at the periphery of a point joined to the plate-shaped portion (Y1) and the thickness B of the plate-shaped portion (Y1) is less than 2.82.
