There are many different plastics in use for model building all with their own uses,this listing is far from exhaustive but gives a cross section as a guide-
High impact polystyrene-This is the material that most plastic kits are made from,versatile,easy to work,easy to bond with ethyl keytone based polystyrene adhesives.
Plastikard sheet-Trade name for a material developed by Slaters,available in many different sizes,sheets,strip and rod,very useful for scratch builders or for modifications to basic kits.
Clear acrylic sheet-Available from DIY shops,modern substitute for perspex which has many uses in model building,comes with protective membrane which is best left intact until the material has been cut to shape,can be moulded.
Sources of clear sheet (various types)-gift boxes,perfumery boxes,florists boxes.
Paxolin-Brown composition material ideal for use with engine mounting plates,can be sawn and sanded but wear a mask as the dust is dangerous and should not be inhaled.
Blue foam-Builders supply insulation foam,makes ideal patterns for use with mouldings,can also be used to make major parts that need to be lightweight.
Main drawback is that you need to buy big sheets,well you do around here !
Can be sanded with Surform,Tungston carbide blocks,Permagrit tools.
Easily sealed with PVA adhesives thinned down 50 per cent.
White foam-Popular for use in making foam wings and fuselage sections that are then covered in thin Obeche veneer or even balsa sheet.
Depren-Toughened surface foam,ideal for use on lightweight models,good sources of supply are meat plates,pizza trays etc use aliphaetic resin adhesives to stick together.
