摘要： A master batch composition for a weight-reduced plastic product includes a bi-component carrier resin, a core-shell foaming agent, and at least one lubricant. The core-shell foaming agent includes at least one outer polymeric shell and at least one inner foaming agent core. The outer polymeric shell encapsulates the inner foaming agent core. The inner foaming agent core includes alkane. The master batch composition is configured to be integrated into the weight-reduced plastic product by extrusion blow molding with a base plastic resin to create a foamed plastic having a foaming pore size from 10 to 80 μm.

摘要： In a method for producing at least a single-walled tubular thermoplastic body in a machine, a nozzle head extrudes at least one tubular preform. The preform is expanded to a predefined dimension in a transverse direction and to a predefined shape in an expansion process using an expanding mandrel, the preform remaining open at the top and bottom. When the at least one preform has cooled off, the expanding mandrel is changed into a non-expanded state and the at least single-walled tubular body is removed from the machine.

摘要： Unitary measuring pipettes include a tubular body of biaxially oriented thermoplastic material, together with size reduction, elimination, and/or reorientation of longitudinally spaced, raised circumferential witness features, to mitigate or avoid interference between such witness features and graduated volumetric markings on an outside surface of the tubular body. Methods and apparatus for vacuum forming of unitary measuring pipettes are also provided. Gas permeable apertures or pores having a maximum width of no greater than 150 microns, in ranges of 10-100 microns, 10-50 microns, or subranges thereof, may be defined in face plates or inserts received by mold blanks, or defined in molding surface of cooperating mold bodies, and may be used to produce a tubular pipette body having reduced height witness features. Cooperating mold bodies may each be produced from multiple mold body sections with gas passages defined therein and/or therebetween.
