A flame-retardant composition including polypropylene, anhydride modified polyethylene and inorganic filler and a rigid molded article prepared with the flame-retardant composition. Also disclosed a method of molding a rigid article from the flame-retardant composition.

A fusible, phase-change powder composition includes a plurality of powder particles comprising a polymer composition, an unencapsulated phase-change material, and optionally, an additive composition; wherein the powder composition is fusible at a temperature of 25 to 105° C., or 28 to 60° C., or 45 to 85° C., or 60 to 80° C., or 80 to 100° C.

The present invention relates to a method for producing foam and foam produced thereby. The method for producing foam includes a step for producing foam by kneading and injection molding a first extrusion product and a second extrusion product, wherein the first extrusion product is obtained by extruding a first composition including an aromatic vinyl-based resin, and the second extrusion product is obtained by extruding a second composition including a polyamide resin and a foaming agent.

The present disclosure is directed to multi-functional isolation pads that can be used in combination with both clamp-on cable trays and guide-on cable trays without any user manipulation (e.g., folding) of the isolation pad.

A thermally expandable composition includes at least one epoxy-functional polymer, at least one endothermic chemical blowing agent, at least one free radical initiator, and at least one guanidine derivative. The invention is also related to a baffle and/or a reinforcement element for hollow structures including the thermally expandable composition, to a process for manufacturing the baffle and/or the reinforcement element, to use of the baffle and/or the reinforcement element for sealing, baffling, or reinforcing of a cavity or a hollow structure, and to a method for sealing, baffling and/or reinforcing a cavity or hollow structure.

The invention relates to an injection-molding composition comprising at least one polyolefin, at least one delignified wood pulp fiber, at least one maleic anhydride-grafted polyolefin and at least one metal oxide chosen from oxides of alkaline earth metals or of zinc.

An encapsulation assembly includes a body located at edges of the functional glass; and a conductive module embedded in the body or located on a surface of the body, and electrically connected to a functional module on the functional glass. The process of forming an encapsulated glass from the encapsulation assembly for a functional glass can omit complicated manufacturing steps and save materials and thus reduce costs. An easy and stable control of the functional module in the glass can also be accomplished. Moreover, it is much easier to form an encapsulated glass from the glass, which facilitates glass mounting.

The present disclosure provides a process. In an embodiment, the process includes providing pellets of a regrind material. The regrind material is a post-consumer recycle multilayer film (PCR multilayer film) having at least three layers. The PCR multilayer film is composed of (i) a polyethylene layer, (ii) a polyamide layer, and (iii) a tie layer. The tie layer is composed of maleic anhydride grafted substantially linear ethylene polymer (MAH-g-SLEP) having a Mw/Mn from 1.5 to less than 3.5 and a melt index from 0.5 g/10 min to less than 25 g/10 min. The process includes extruding the pellets to form an extrudate, molding the extrudate, and forming, with the extrudate, a molded article having a surface. The surface of the molded article has a surface roughness value, Sa, less than 1000 nm and a root mean square roughness value, Sq, less than 1400 nm.

Disclosed is an airtight container including a main body with an opening, and a cover, the airtight container including: an edge portion to press a sealing edge formed at an upper end of the main body; a locking clamp including an engaging portion to engage with an engaging-portion holder extended from the sealing edge or formed in a lateral wall; and a hinge provided between the edge portion and the locking clamp and including a material to be folded and unfolded with respect to the edge portion so that the engaging portion can be locked to and released from the engaging-portion holder. Thus, there is provided an airtight container with a soft hinge and a double injection-moulding structure, which is improved in durability because the hinge is prevented from damage even though it is used for a long time.

An injection molding machine for foam molding includes: a heating cylinder; a screw disposed in the heating cylinder; and a plurality of inlet portions provided in the heating cylinder and configured to introduce inert gas. An inside of the heating cylinder includes a starvation section on an upstream side in which a pressure of the resin is decreased, and the inert gas from the plurality of inlet portions being to be supplied in the starvation section. Each of the plurality of inlet portions is provided with a check valve or an opening and closing mechanism. A product P×N of an interval P of the plurality of inlet portions and a number N of the inlet portions is 0.5H or more and 1.71H or less with respect to a length H of the starvation section.
