PLASTICS

Description: "HOLOPLAST" PANELS 1. (a) Increase in superficial dimensions and thickness. (b) Increase in dimensions with blistering from prolonged contact of the laminates with water - approx. four weeks. Salt water can cause damage to laminated sheets with decorative surfaces. (c) As with (b). Dimensional changes can be adjusted by drying at low temperatures (say 60 degrees C) but if the material has reached the stage of being blistered nothing can be done to recover it. (d) In the drying process it is preferable that both surfaces of the laminates be treated simultaneously, otherwise warpage may result, although this should be of a temporary nature only. 2. (a) Warpage, change of surface texture, blistering or charring, depending on the intensity of the heat. (b) It is possible in some cases to readjust warpage and it is possible in the case of stove enameled laminates for the enameling process to be repeated but sheets which are blistered and charred are irrecoverable. This material has no inherent vice other than referred to above, but should be kept away from heat and stored in a dry, cool place - not on deck. THERMOSETTING LAMINATED SHEET 1. (a) Increase in superficial dimensions and thickness. (b) & (c) Increase in dimensions with blistering from prolonged contact of laminates with water - approx. four weeks. (d) No. 2. (a) Warping, change of surface texture, blistering or charring, depending on the intensity of the heat. (b) ) No. This material should not suffer from any inherent vice, but calls for storage in a dry place. Hooks should not be used.
