Methyl butadiene styrene (MBS) and acrylic (PMMA), which are used widely as impact modifiers for PVC and engineering resins, also function as processing aids, for rigid and semi-rigid processes and applications, such as blow moulding, calendering, profile extrusion, and injection moulding of technical parts. Some types can also be tailored to suit specific requirements. [Pg.200]

We have previously reported a practical and cost-effective method to obtain PDMS-polyolefin compounds by reactive melt mixing of an ethylene-ethyl acrylate-maleic anhydride (EEAMA) copolymer and aminopropyl terminated PDMS. In this study, the PDMS-modified polyolefin (PMPO) is used as a processing aid for the extrusion of a LLDPE. Improvements in extrudate surface quality and shear stress reduction after adding 5 wt% of PMPO with different levels of PDMS content are presented and related to changes in the surface free energy of the PMPO. The friction coefficients of PMPO and its compounds with LLDPE were measured in an effort to provide experimental support of the observed behavior. [Pg.2034]

Extrusion of tubes, hose, and profiles is done on standard extruders for rubber. The usual temperature pattern is a gradual increase of temperature from the feed zone to the die. The die temperature is typically 100°C (212°F) and the screw temperature is approximately the same as the temperature of the feed zone.37 Processing aids are almost always required to improve the surface appearance and to increase the extrusion rate. Extrusion represents only a small proportion (about 10%) of the total consumption of fluorocarbon elastomers.37... [Pg.104]
