An expression Ho × 0.4 ≤ H ≤ Ho is satisfied where H is a maximum height for an unbroken first plate-like test piece having a thickness of 1 to 2 mm after the test piece is kept at -10° C. for three hours and then is hit by a dropped weight of 250 g; and Ho is as same maximum height for the unbroken second plate-like test piece only made of the base resin with a thickness of 1 to 2 mm as for the first plate-like test piece. An expression So × 0.4 ≤ s ≤ So is satisfied where S is a Charpy impact strength (JIS K 7111) of the molded article, and So is a Charpy impact strength of the molded article only made of the base resin.

A feeding and blending apparatus for a system for continuous processing of powder products comprises at least two system inlets for powder products; and at least two feeding and dosing devices arranged in a row. Each of the at least two feeding and dosing devices comprises, an inlet being connected with a system inlet, at least one feeder, at least one actuator configured to operate the at least one feeder, and an outlet being connected with an inlet of the powder blending device. A separation wall is configured to separate a process area from a technical. Process components of the at least two feeding and dosing devices are positioned in the process area and technical components of the feeding and dosing devices are positioned in the technical area. Connections between the at least one actuator and the at least one feeder pass through the separation wall.

A method for producing a foam-molded product by using a plasticizing cylinder, includes: plasticizing and melting the thermoplastic resin to provide the molten resin in a plasticization zone of the plasticizing cylinder; introducing a pressurized fluid containing the physical foaming agent at a fixed pressure into a starvation zone of the plasticizing cylinder to retain the starvation zone at the fixed pressure; allowing the molten resin to be in the starved state in the starvation zone; bringing the molten resin in contact with the pressurized fluid containing the physical foaming agent at the fixed pressure, in the starvation zone in a state in which the starvation zone is retained at the fixed pressure; and molding the molten resin having been brought in contact with the pressurized fluid containing the physical foaming agent into the foam-molded product.

A deodorization method and apparatus are disclosed to eliminate, reduce or correct the odour of incoherent plastics, i.e. in the form of granules and/or microgranules and/or powder and/or flakes or the like, with a container of the incoherent plastics, an actuator for generating a process gas flow from a gas inlet to a gas outlet of said container, an olfactory sensor arranged to detect odorous emissions in the process gas exiting from said container, a controller configured to control at least one parameter of the process gas on the basis of an odour intensity measured by said olfactory sensor, with the aim of eliminating the substances that cause undesired odours from the incoherent plastics that is usable in a transformation process to make an end product.

A foam dispensing apparatus and system thereof can be used for dispensing a mixture of a resin component and an isocyanate component. The foam dispensing apparatus contains a heated hose assembly, a spray gun containing a spray head and a mix tube, and a nozzle for dispensing the resin and isocyanate components from the spray gun. Components of the foam dispensing system are lightweight and/or low cost thereby facilitating use and maintenance.

A charging system for feeding processing material to at least one extruder screw including a hopper configured to conduct the processing material along a feed direction to the extruder screw, and a material reservoir for the gravity-driven feeding of the processing material to the hopper. The charging system also includes a feeding device via which processing material recirculated at the hopper against the feed direction by action of the extruder screw can again be conveyed in the direction of the extruder screw together with processing material fed from the material reservoir.

A system for adjusting a gap in a slot die for producing a polymeric web. The system includes a slot die that has a polymer reservoir that extends between a polymer inlet and a melt outlet. The melt outlet has a first edge and a second edge that each extend longitudinally along the melt outlet. The second edge is opposite the first edge. A plurality of actuators move the second edge along a plurality of positions along a length of the second edge. The first edge is spaced apart from the second edge by a gap that has an adjustable profile. A pressure sensor communicates with the reservoir and measures the pressure of the polymer in the reservoir. A control unit with an algorithm correlates the profile of the gap to the pressure in the reservoir. The algorithm is configured to generate control signals to cause the profile of the gap to be uniform.
