According to the "New Zealand Herald" report, the Advanced Composite Materials Research Center of the University of Oakland recently successfully synthesized two types of cheap waste plastic into a new type of advanced plastic.
They synthesized a new polymeric plastic from used polyethylene plastic milk bottles and PET cola bottles. Tests have shown that the performance of this new type of plastic is significantly better than that of the two raw materials. It is harder than any kind of raw material, and the effect of isolating oxygen is increased by 2-3 times. It is very suitable for food packaging materials. The research center also found that the addition of suitable additives has enhanced the electromagnetic shielding capabilities of this new type of plastic, making it an ideal packaging material for electronic products. What is more significant is that this new material can be recycled for several uses without degrading the performance. At present, this new type of plastic production machine has also been designed and manufactured by the center, with a daily production capacity of several hundred meters.
The successful synthesis of this new plastic is mainly due to the fact that the two raw materials have different melting points that differ by at least 40 degrees. When the milk bottle and the Coke bottle are melted together, the PET having a higher melting point forms tiny fibers having a diameter of micrometers or even nanometers. The small fibers are evenly distributed in the new material and greatly increase the strength and hardness.
