Plastics knowledge: Rapid identification of PC recycled materials

PC plastic is called polycarbonate. Due to the high price of raw materials, some illegal elements often use recycled materials as substitutes to manufacture products that should be used as raw materials, such as medical equipment, purified water buckets, and helmets. According to Zhuo Chuang, the bucket market is no longer a secret. However, before the domestic use of PC recycled materials, there is no fixed determination method, can only rely on the appearance of color, gloss, cut surface regularity, combustion and drawing conditions to roughly determine.

Recently, the Fujian Provincial Provincial Quality Inspection Institute research project “Research on the Rapid Detection Method of Polycarbonate and Its Recycled Products” concluded its research results and was the first in China to rapidly identify PC recycled materials. The research project measured the melt flow rate (MFR), heat loss weight temperature, molecular weight size, and molecular weight distribution of different grades of PC raw materials and primary recycled materials, secondary recycled materials, to determine whether the product was processed using recycled materials. Quick identification method.
