Hi AllI want to make plastic .. can any one tell me how i can make plastic.. because I have to made some holders of the car roof top racks..
You can't really make (synthetic) plastic unless you're a serious chemist with a lab, but you can use other plastic materials and reshape them. You'd need serious molds and vacuum setups to create large items like that chair too. Small items or thin ones can be made with a thermosetting plastic like polymer clay --Premo, Fimo, etc, or thermoplastic or other plastics can be re-shaped after heating which will either soften and slump or eventually melt them, or with 2-part resins (with fiberglass or not), etc
I don't know if this would really be that good of a tough plastic but fusing a lot of plastic bags makes it pretty hard. Just get some plastic bags on top of each other, sandwich them between parchment (or wax, but preferably parchment) and iron it for about 20 to 30 seconds on a medium heat always making sure that the iron is constantly moving,
