Methods of manufacturing bulked continuous carpet filament which, in various embodiments, comprise: (A) grinding recycled PET bottles into a group of flakes; (B) washing the flakes; (C) identifying and removing impurities, including impure flakes, from the group of flakes; (D) adding one or more color concentrates to the flakes; (E) passing the group of flakes through an MRS extruder (400) while maintaining the pressure within the MRS portion (420) of the MRS extruder (400) below about 25 millibars; (F) passing the resulting polymer melt through at least one filter (450) having a micron rating of less than about 50 microns; and (G) forming the recycled polymer into bulked continuous carpet filament that consists essentially of recycled PET.

A method for manufacturing pellets from polymer, comprising: (1) melting polymer flakes in a first section of a melt processing unit to create a first single stream of polymer melt; (2) separating the first single stream of polymer melt into multiple streams of polymer melt by means of a separation element; (3) passing the multiple streams through a multiple stream section of said melt processing unit and exposing the multiple streams to a pressure within the multiple stream section of the melt processing unit as the multiple streams pass through the multiple stream section; (4) recombining the multiple streams into at least one combined stream of polymer melt; and (5) cooling the polymer melt and forming said pellets from the at least one combined stream. The intrinsic viscosity of the at least one combined stream may be determined and, in response, the chamber pressure within the multiple stream section adjusted.

One aspect of the present invention is a method for producing an ethylene vinyl acetate hot-melt adhesive, comprising: introducing a liquid including at least one of water and alcohol into a heating kneader while or after kneading a hot-melt adhesive material in a liquid state, at an amount of 0.05 parts by mass or more with respect to 100 parts by mass of the hot-melt adhesive material; and performing vacuuming while heating stirring or dispersing the hot-melt adhesive material and the liquid so as to come into contact with each other.

A method of producing a compound for bonded magnets, the method including: heat-curing a thermosetting resin and a curing agent having a ratio of the number of reactive groups of the curing agent to the number of reactive groups of the thermosetting resin of at least 2 but not higher than 11 to obtain an additive for bonded magnets; and kneading the additive for bonded magnets, magnetic powder, and a thermoplastic resin to obtain a compound for bonded magnets in which a filling ratio of the magnetic powder is at least 91.5% by mass.

The invention relates to a low pressure extruder (3) for manufacturing a low density plastic composite material, characterized in that, the volume between the cylinder and the screw per unit length is not decreased along the direction from the hopper to the die in order that the mixture is extruded at low pressure in the melted state out of the cylinder of the extruder; the die is heated by the heater to maintain the melted state of the material in order not to create resistance to the flow in the process of pushing the material mixture out of the cylinder of the extruder. Furthermore, the present invention provides a method and equipment for manufacturing this material.
