The process includes the steps of supplying a bimodal or multimodal polyolefin in form of a polyolefin powder to the hopper; (a) measuring the flow rate of the polyolefin powder or (b) measuring the flow rate of the prepared polyolefin pellets; supplying one or more additives to the hopper; adjusting the flow rates of the additives supplied to the hopper in response to the measured flow rate of the polyolefin powder or adjusting the flow rate of the polyolefin powder in response to the measured flow rate of the polyolefin pellets; melting and homogenizing the polyolefin powder and additives within the extruder device; and pelletizing the molten polyolefin composition into the polyolefin pellets.

Thermoplastic compositions are described that exhibit resistance to hydrocarbon absorption. Methods for forming the thermoplastic compositions are also described. Formation methods include combining a polyarylene sulfide with a first impact modifier and a second impact modifier such that the impact modifiers are dispersed throughout the polyarylene sulfide. A crosslinking agent can be combined with the other components of the composition following dispersal of the additives throughout the composition to dynamically crosslink at least one of the first and second impact modifiers.

A producing method for producing a foam-molded product by using a plasticizing cylinder having, from an upstream side in the following order: a plasticization zone, a flow rate adjusting zone and a starvation zone, the producing method includes: plasticizing and melting a thermoplastic resin into a molten resin in the plasticization zone; adjusting a flow rate of the molten resin in the flow rate adjusting zone; allowing the molten resin to be in a starved state in the starvation zone; introducing a pressurized fluid containing the physical foaming agent having a fixed pressure into the starvation zone so as to retain the starvation zone at the fixed pressure; bringing the molten resin in the starved state in contact with the pressurized fluid in the starvation zone in a state in which the starvation zone is retained at the fixed pressure; and molding the molten resin into the foam-molded product.

Thermally vulcanisable, meltable adhesives and processes have a meltable polybutadiene-polyurethane, ground sulphur and optionally at least one vulcanisation accelerator, at least one filling material, at least one epoxide resin, at least one tackifier resin, bitumen, at least one softener and further auxiliary and additive materials, wherein said adhesives and processes can be thermally vulcanised within a temperature range of 130° C. to 230° C., such that same, as well as an adhesive strip produced from same, can be used for adhesion and/or sealing in the automotive industry, as well as in structural work on oiled sheet metal, and in the painting line on e-coated or otherwise painted sheet metal, for example, for crimp fold adhesion, for crimp fold sealing, for seam sealing, for lining adhesion, for hole closure and much more.

A method for operating a mixing apparatus of a manufacturing plant comprises supplying multiple powdered products to the mixing apparatus. An inlet mass flow rate of the multiple powdered products into the mixing apparatus and a weight of the multiple powdered products in the mixing apparatus are measured. The multiple powdered products in the mixing apparatus are mixed to form a mixed product. The weight of the multiple powdered products in the mixing apparatus and an outlet mass flow rate of the mixed product from the mixing apparatus are predicted based on the measured inlet mass flow of the multiple powdered products. The predicted outlet mass flow rate of the mixed product from the mixing apparatus is corrected based on the measured weight of the multiple powdered products in the mixing apparatus. The mixed product is processed into final products
