Definitions

  • Fig. 1 is a graphical representation of the slip- producing effect of certain fatty acid amides in PET.
  • a range of Laser "1" PET formulations were injection moulded into parison tubes, or preforms.
  • the moulding was carried out at 260°C under identical injection moulding conditions.
  • the formulations comprised representative samples with different additives selected from oleyl palmitamide and stearyl erucamide at a concentration of 0.1% by wt and one control formulation (Laser + with no additive) .
  • the preform samples were moulded using a Negri Bossi NB90 molding machine.
  • an extra batch of Laser + control preforms were moulded using a Husky XL 160 molding machine for comparison. Each preform sample was allocated an identification number. The start and finish time/date of moulding was recorded allowing the time of moulding of each preform to be estimated.
  • a crossed cylinder apparatus gave a good reproducible contact geometry (similar to sphere on flat) .
  • the preforms had a relatively small diameter and were quite stiff, deforming only slightly with the normal load, giving a small contact spot and shear forces of a magnitude that were easily measurable.
