Just wondering, I have some parts of a project Iâ€™m working on and the original intention was to injection mould these parts from ABS. the parts are the out casings of something similar to a hard case backpack. Some people have questioned the material choice and asked why I havenâ€™t used High Impact Polystyrene (HIPS). I donâ€™t know a great deal about it, other then what you can read in a book or find online.
My question is what would be the advantage of using HIPS over ABS, what significant comparisons can be made.
