Above some is right some is wrong. If you have transparent parts you can use clear ABS, AS or SAN, PC, PP, HIPS,PMMA. ABS is good for composite feature. PC is good for mechanical and theormal performance. SAN and PMMA is good for optics performance. But they are easy to break. PP is good for folding up, but it is soft usually. It is very cheap. HIPS can be used to instead of ABS if the impact requirement is not too high. If it is not clear. We can use ABS. PC. PC/ABS. PC/PS. If your product's elctric voltage is high you have to add some imflame additive. such as UL code. 94HB. V0., V5 etc. Like Epson's printer use HIPS but no inflame additive so that it was firing in Europe. Now it almost lost the whole Europe market. |
