A combination of materials that may be formed through an extrusion process. The resulting product has at least two layers. By coextruding multiple layers of at least two types of materials together, the final product may have improved mechanical, thermal, electrical, and other properties as compared to the original materials used. Additionally, by using an additive, filler, or doping material in at least one layer of the final product during the extrusion process, the mechanical, thermal, electrical, or other properties of the final product may be further improved.

A prepreg includes composition elements [A], [B], and [C] described below, [A] a reinforcing fiber, [B] a thermosetting resin, and [C] a thermoplastic resin. [C] is present on a surface of the prepreg, [B] contains a first curing agent [b1] and a second curing agent [b2], and the reinforcing fiber of [A] that crosses over a boundary surface between a resin region containing [B] and a resin region containing [C] and that is in contact with both resin regions is present.

A film comprising a perforated layer, wherein the perforated layer is characterized by water vapor transmission rate (WVTR) of at least 300 gr/m2/day; and wherein the perforated layer is characterized by a liquid permeability of less than 0.6 gr when measured according to AATCC 35. Further, methods of manufacturing the composition of the invention are provided.

Provided is a layered product that uses a high temperature-resistant transparent film having sufficient heat resistance, and that is capable of being mechanically released from an inorganic substrate after various processes are performed on the inorganic substrate since the adhesive strength between the high temperature-resistant transparent film and the inorganic substrate is appropriately weak, and that is less warped along with the inorganic substrate. In this layered product, no adhesive is used between the high temperature-resistant transparent film and the inorganic substrate, the release strength between the high temperature-resistant transparent film and the inorganic substrate is at most 0.3 N/cm, and the warpage amount of the layered product when heated at 300° C. is at most 400 .Math.m.

The present invention relates to an ethylene-vinyl alcohol copolymer composition, a single-layer film and a multilayer structure containing the same. Said ethylene-vinyl alcohol copolymer composition includes an ethylene-vinyl alcohol copolymer, an antioxidant, and a fluorine-containing compound; and the ratio of the antioxidant content to the fluorine content is 0.5 to 65. Thereby, the film containing said ethylene-vinyl alcohol copolymer composition not only has good heat resistance, but also can avoid the situation that a large number of gels are generated during the preparation process.

A method for forming a multilayer plastic sheet material (1) for floor and/or wall panels, wherein a first polymer mass comprising a rigid PVC is melted under pressure and is passed through an extruder head at a specified discharge rate in the form of a plastic strand in sheet form that is provided with one or more layers so that a multilayer plastic strand is formed, which is passed to two or more rolls of a finishing stand, which processes the multilayer plastic strand into a sheet of defined thickness, which is then led away via a transport device to a sawing device to be cut to the desired length, wherein, after the plastic strand in sheet form leaves the extruder head, it is first passed between a top roll and a bottom roll of a roughing stand, wherein the speed of the rolls of the finishing stand and the rolls of the roughing stand is synchronized with the discharge rate of the plastic strand in sheet form from the extruder head, so that said plastic strand is processed without stress.
