I want to bend some clear crystal polystyrene, how do I do it? Answered

Poly is from CD jewel boxes. Need to bend to a curved aerofoil shape. Hair dryer? Microwave? Oven? Any ideas welcome. Ray



You may have problems with this. An oven would work with a good degree of temperature control, but upon cooling you may not get what you want - these things can warp and for crystalline opaque regions. Oven probably best, Google for "polystyrene glass transition temperature" or "polystyrene melting point" L
