hello, asking what ingredient and procedures to make bioplastic water resistant? since its starch base it will be wet and sticky once sprinkled/spashed in water. Thanks.
@sSyreNe21 Glycerin+vinegar can be replaced with vegetable oil (very little, 2-3 drops per a tablespoon of starch, serves as a plasticizer). In that case starch and water are better to be equal volume (if you're not sure about that, add a bit more water, most important is no excess starch after heating).
Hello mi name is Helena im from Colombia and i need to to present my chemistry project about bioplastics, could you say me how was your procedure to do the bioplastic so hard becouse i get it very soft ,and which were the materials, please help me !!!
Maybe it's a good idea to apply some water based resin first, and then apply the bioplastic. Exactly how hard does it get? Is it as hard as normal ABS plastic?
@locombianisimo01 No i haven't been in the 405th scene in a while...i made one helmet, and i pepped it, and then i covered it in elmer's glue and rubber cement for a hween costume. i used some partially clear binder dividers for the visor. It was pretty beast for only taking a week to make.
@locombianisimo01 I have. It's not sturdy enough to make smth serious out of it. :( That's because casein is not a complete polymer, it's polymer-like. Starch-based plastic is complete polymer. I've cooked a piece of this plastic (potato starch + veg oil + water) and I can throw it as hard as I want and it doesn't break.
@locombianisimo01 Mix 50% (vol) of potato starch and 50% of water. Then add a bit veg oil (2-3 drops per one tablespoon of starch). Then, the same: heat while stirring and then mold.

Ive got a question , If you put the bioplastic when its in gel to the paper , the paper deforms ?
ManuTraceurMDZ 2 years ago
wow actually a non fumes form to make a replace to the resin,have a question have you tried the milk and vinegar bioplastic ?
thanks

@locombianisimo01
milk and vinegar doesn't make plastic. it makes cheese. haha. not good at all for making armour. i've tried it. lol.
