I have two questions in one. Is it possible to make a bioplastic that’s flexible and nondegradable?
If so, do you know anyone who can do this or is there a way to do this?
bioplastic durability flexibility
There are manufacturing and chemical processes that can be used to make plastics from renewable resources (i.e. bioplastics) that are NOT degradable… however, this is not a process you can do in your own home.
But we have talked about one such type of plastic here:
“green polypropylene” is the product, and there are more links about it in that article. It is made from sugar cane, but because of the way that they process it, the end result is completely non-biodegradable.
I myself have achieved the flexibility but not quite the durability. Its hard to know what your standards are since they are qualitative. If you are using cornstarch there are two variables that you should try manipulating. a) the glycerol to starch ratio b) the water to starch ratio. Try increasing glycerol and especially try decreasing water ratio. The less water, the fewer chemical bonds formed in the plastic.
Hello! My friends and I are trying to invent our own bioplastic polymer to make into a balloon. We have been using sorbitol, arrowroot starch, agar, 1% glycerol solution, and water. (we’ve also made agar only plastic). We were wondering if you could explain more about the function of each ingredient. Which ingredients are the plasticizers and which are the ones that form polymers? We’ve managed to make a prototype that can hold air for 3 1/2 hours or so, but we need to make it lighter. Also, we are having trouble heat sealing the polymer. Any ideas on how to make this work?
Thanks for you help!
