Primo is a leader in the plastic extrusion business and has existed for more than 60 years. The company is supplying different leading businesses in different industries with the absolute best ...

The extrusion process initiates orientation of the chains in the extrusion direction (Fig. 1 left). Drawing or pulling on the extruded monofilament further orients the polymer chains in the machine ...

Polymer degradation has an immediate impact on the final plastic product and its properties. In the plastic extrusion process, increased temperatures, as a result of the melt processing, in ...

David (SC Consultants): Mechanistic [extrusion experts] understand the relation between torque, flow rate, RPM, residence time, shear rate, etc. These relations are generic and valid in the polymer ...

Scientists at Oak Ridge National Laboratory have developed a vacuum-assisted extrusion method that reduces internal porosity — by up to 75% — in large-scale 3D-printed polymer parts.

Polymer Packaging Inc. is jumping back into the extrusion business after more than a decade of absence, spending more than $10 million on equipment to start film production soon on a pair of three ...

Hot melt extrusion (HME) formulation development depends heavily on choosing the appropriate polymers. This article reviews HME process parameters and highlights three polymers in HME: polyethylene ...

The samples were prepared according to the formulae in Table 1. The preparation included the one-step extrusion process and the two-step extrusion process, which are shown in Figure 2.
