extrudate

extrudate

[′ek·strə‚dāt]
(engineering)
Ductile metal, plastic, or other semisoft solid material that has been shaped into a continuous form (such as fiber, film, pipe, or wire coating) by forcing the semisolid material through a die opening of appropriate shape.

A systematic way is proposed to analyze and model changes in individual extrudate dimensions in terms of size (symmetric) and shape (non-symmetric) changes along the extrusion line.
The new version of Plastic Flow's polyXtrue software allows users to accurately simulate extrudate cooling and shrinkage.
Screw speed had the greatest effect on extrudate quality.
For profile extrusion with calibration in a water bath, air bubbles on the extrudate greatly reduce the cooling rate and process output.
The screened extrudate was suspended in water at room temperature (25[degrees]C) at a 1: 10 ratio, stirred for 10 min, and the supernatant was decanted by centrifugation at 1000 xg for 15 min.
General melt fracture behavior of HDPE resins in a capillary extrusion is well understood, and the physical mechanisms have been discussed in comprehensive reviews [1, 3], At low shear rates, the extrudate usually is smooth and exhibits no melt fracture.
Extrudate texture were measured for 10 samples per treatment using a TA.XT2.Plus texture analyzer (Stable Micro Systems, Surrey, England), with a 50kg load cell and a HDP/ WBV probe and a test speed of 1 mm/ s (TAVERNA et al., 2012).
An adjustable cutter with four blades facing the die was operated at 300 rpm to cut the extrudate as it emerges from the extruder.
Samples may be taken of the extrudate and tested further, for example by various thermal analysis techniques, tensile testing, microscopy and others, to build a picture of how the act of processing effects the structure and properties of the extrudate.
KGaA, Dusseldorf, Germany, has been awarded a patent for a washing and cleaning agent shaped body that is silicone-free and is in the form of a granulate, extrudate, agglomerate or tablet.
The invention relates to a composition comprising a polymer and wood fiber composite that can be used in the form of a linear extrudate or thermoplastic pellet to manufacture structural members.
