Problems solved by technology

At present, it can be applied to catering utensils, daily necessities, agricultural materials, biomedical polymer materials, food and drug packaging materials, etc., but PBS materials directly used for 3D printing have not been reported yet.
[0006] The direct application of pure PBS to 3D printing has the problem of heat shrinkage, and the main chain of PBS is composed of aliphatic carbon-oxygen chains, so the toughness and tensile strength need to be further improved
