The values in Table 2 also show that for comparable
crosshead speeds or strain-rates the MDF specimen type yields higher values of [alpha] than the SP type.
4 showing the relationship between the logarithm of the oscillation frequency and the reciprocal of the absolute temperature with the
crosshead speed at 0.84 mm [min.sup.-1].
The plan of the experiment is developed for assessing the influence of the weight fraction of silica, SBR, and
crosshead speed.
Three
crosshead speeds of 5, 30, and 60 mm/min were used to investigate the effect of straining rate on the resistance of the damage to fracture, characterized by the values of UTS, extension at break, and toughness (defined as the energy consumption during the test, i.e., the area under the load-displacement curve).
At least three specimens were tested for each
crosshead rate or rubber content.
The toughening mechanisms were examined, and variations of fracture toughness with rubber content and
crosshead rate were discussed.
The Series 712 CircuitFlow
crosshead is a low-volume design for 45 AWG to 10 AWG wiring sizes.
The use of BN as a processing aid of polyolefins and fluoropolymers is more effective when extrusion experiments are carried out using a special
crosshead die of the type used in wire coating operations.
One is a modular rotating and oscillating screw extruder and the second is a
crosshead screw extruder with a screw that only rotates.
The Series 725 co-extrusion
crosshead is designed for tray cable applications.
FinnProfiles developed a process using two extruders and a special
crosshead die to keep the silicone profile from contacting the intumescent strand until it has cooled.
