초록 ▼

A polystyrene foam sheet comprising a polystyrene resin which contains 1 to 15 wt % of a rubber component having a majority of particle sizes less than about 0.45 microns has been found to be superior for forming deep drawn articles. Optionally one or two films may be extrusion coated or laminated to the foam sheet prior to thermoforming. Also disclosed is a method for thermoforming the foam sheet. Preheat the sheet, clamp the sheet between the matched male and female mold members, move the members into final position while applying a vacuum through both members to both sides of the foamed sheet and then chill formed foam to set a final shape.

대표청구항 ▼

A method of thermoforming deep drawn thermoplastic foam articles comprising, in sequence, the steps of: a. preheating a sheet of thermoplastic foam stock material which contains 1 to 15 wt % of a rubber component having a majority of particle sizes less than about 0.45 microns with the foamed sheet having a density of 0.04 to 0.16 g/cm3 (2½-10 lb/ft3) and a thickness of 0.4 to 6.5 mm; b. clamping said preheated stock material in a fixed position between matched male and female mold members; and c. relatively moving said male and female mold members into final forming position to stretch said sheet into said cavity; d. applying a vacuum through both the male and female mold members to both sides of the foamed sheet, while performing step c), to help expand the sheet into conformity with substantially the entire cooperating surfaces of the mold members; and e. chilling the stock material to set a final shape.
