Why is glass fiber reinforced polycarbonate plastic cadmium?
The guess could be glass fiber introduction. The original plastic usually contains no heavy metals, but it's hard to say what to do
There are 2 possible reasons:1, PC contains impurities, such as recycled materials, the quality of this is difficult to guarantee, all may be impurities in cadmium, so that products detected;2, for the production of machine pollution, if the previous production of the machine produced environmentally friendly products, and in the glass fiber reinforced PC, the machine is not cleaned thoroughly, then the residual substances will be brought into the product.Problems can be investigated from raw materials (fiberglass, PC, additives), processing equipment, packaging materials, one by one to exclude, so that you can find the root of the problem, I hope to help you.
It must have been contaminated at any point, or the raw material has been contaminated. Otherwise, how could it be possible?. Look, fiberglass and PC are environmentally friendly. The equipment is clean and has not been made environmentally friendly before.
