FOAM PRODUCT AND MANUFACTURING METHOD THEREOF
The present invention disclosed a foam product and the manufacturing method thereof. The foam product includes a foam core, an outer skin, a cross-linked foam sheet and a bottom plate, wherein the aforementioned layers are all pre-made. The cross-linked foam sheet is laminated onto a bottom surface of the foam core, and the outer skin is then laminated onto a top surface and a periphery of the foam core. Lastly, the bottom plate is laminated onto the cross-linked foam sheet, wherein, the bottom plate has a non cross-linked foam sheet and a non-foam plastic plate, so that when the bottom plate is laminated onto the crossed-link foam sheet, the non cross-linked foam sheet is sandwiched between the cross-linked foam sheet and the non-foam plastic plate.
EXTRUDED SEALED FASTENER
A method of forming a plurality of fasteners includes extruding a continuous strip of material, the continuous strip defining a base portion, a tip portion, and a stem portion extending between the base portion and the tip portion. A portion of material is removed from the continuous strip of material along the tip portion such that a plurality of tip portions are separated from each other and spaced apart, each tip portion having at least one flexible tab. The continuous strip of material is then extruded through a foaming die, wherein the flexible tabs are elastically displaced away from the base portion during a foaming process such that a foam material fills a cavity of the foaming die to form a sealing element around the stem portion. Portions of the continuous strip between each of the tip portions are separated to produce a plurality of individual sealed fasteners.
RESIN FOAM PRODUCTION APPARATUS AND METHOD OF PRODUCING RESIN FOAM
A resin foam production apparatus is provided including: a metal mold including a foaming part and a discharge part; and an extruder configured to feed a resin foamable composition into the metal mold to cause the resin foamable composition to pass through the discharge part. The resin foamable composition comprises at least one type of resin. A ratio of resin pressure Cp2 at the foaming part of the metal mold relative to resin pressure Cp1 generated by the extruder is 0.3 or more.
Hollow porous fibers
A hollow fiber that generally extends in a longitudinal direction is provided. The hollow fiber comprises a hollow cavity that extends along at least a portion of the fiber in the longitudinal direction. The cavity is defined by an interior wall that is formed front a thermoplastic composition containing a continuous phase that includes a polyolefin matrix polymer and a nanoinclusion additive dispersed within the continuous phase in the form of discrete domains. A porous network is defined in the composition that includes a plurality of nanopores.
FOAMED FLOOR WITH WOOD TEXTURE
The disclosure relates to a foamed floor with wood texture. It belongs to the technical field of co-extruded foam plate. It includes a foam matrix and a hard surface layer including (a) and (b); (a): a first exposed surface, a connecting substrate and a base layer formed by the first color resin; (b): a second exposed surface and a connecting substrate formed by the second color resin. The first exposed surface is composed of a plurality of exposed units, and the second exposed surface is composed of a plurality of sunken units. The exposed units and the sunken units are arranged alternately. A connecting unit is arranged between the adjacent exposed unit and the sunken unit, and it's composed of the connecting substrate and a connecting profile. The disclosure uses resin as a material, is based on two surface layers, and realizes the realistic effect of wood texture through some levels of expressions such as three-dimensional (depth of texture), color difference, brightness etc. It can also realize a variety of wood textures by adjusting the three-dimensional, chromatic aberration, and brightness.

Moreover, the invention relates to a method for producing a container, in particular a bottle (30) for storing and optionally applying a liquid, solvent-containing composition, having a multi-layer wall (20), as well as use of a multi-layer wall (20) for producing the container (30).
PROCESS FOR PRODUCING LAMINATED FOAM SHEET AND EXTRUDED LAMINATED FOAM SHEET
A laminated foam sheet having a polyethylene resin foam layer and an antistatic polyethylene layer laminated on one or both sides thereof is produced by coextruding melts for respective layers, wherein the melt for the antistatic layer contains a polyethylene resin, an ionomer resin antistatic agent and a specific amount of volatile plasticizer blend containing an alcohol and a saturated hydrocarbon or a dialkyl ether. The antistatic layer of the obtained laminated foam sheet has specific morphology.
Method and device for determining a layer property of a layer in an extrusion process
Method for determining at least one layer property of a layer to be determined, in particular a foam layer, in an extrusion process, where a supply material is at least partially foamed and an extrusion product with the foam layer is put out (in other words, is output).
