Title: Extrusion blowing film from chemically expanded plastics - to vary film orientation without using different mandrels
Inventor: LOZACH GUY
IPC: B29D7/01
Filed: 1975-02-24
Abstract: Thon, low density sheet is made by extrusion blowing thermoplastic compsns. contg. mineral fillers and chemical blowing agents. The extrusion die can discharge a cooling fluid at high throughputs within the bubble and can extract excess coolant at rates controlled to balance the dimensions of the bubble against fluid losses by permeation. The process is used esp. for making film of expanded crystal or toughened polystyrene from compsns. contg. 3-5% wt. pulverised talc and 0.8-1.2% azodicarbonamide. Adjustment of the fluid injection press. and of the haul-off rate provides good control of the relative rates of longitudinal and lateral extension of the extrudate. The process does not involve use of an internal mandrel and consequent restriction of radial expansion ratios with respect to the die dia. The surface finish of the prod. is better than that for material extruded using physical blowing agents (e.g. pentane) and lower extrusion temps. The press. loss through the walls of the bubble automatically damps variations in the bubble dimensions in response to any variations in the press. at which the coolant is injected.
