New Zealand synthesizes waste plastics into advanced new packaging materials

it is reported that the advanced synthetic materials research center of the University of Auckland has successfully synthesized two kinds of cheap waste plastics into an advanced new plastic

they synthesized a new polymer plastic from waste polyethylene plastic milk bottles and pet cola bottles. The test shows that the performance of this new type of plastic is significantly better than that of the two raw materials. The hardness of any raw material is greater than that of the water contained in the plastic, which will evaporate into the air, and the effect of isolating oxygen is improved by 2 ~ 3 times. It is very suitable for food packaging materials. The research center also found that after adding appropriate additives, the electromagnetic shielding function of this new plastic is greatly enhanced, and it is an ideal packaging material for electronic products. More importantly, this new material can be recycled for several times without degradation of performance. At present, the production equipment of this new type of plastic has also been designed and manufactured by the center

the main reason for the successful synthesis of this new type of plastic is that the two raw materials have different melting points with a difference of at least 40 ℃. When milk bottles and Coke bottles melt together, pet with a high melting point forms tiny fibers with a diameter of microns or even nanometers. These small fibers are uniformly named te COPD and distributed in the new material, greatly improving the strength and hardness

at present, this new material is applying for a patent and is in the preparatory stage of commercialization

cobalt price rises, so the size is as close to 25mm as possible × 25mm header statement:
