How to solve the odor problem of flame - retardant corrugated pipes?

The competition in the automotive field is becoming increasingly fierce, and automotive manufacturers are setting higher and higher requirements for the odor and VOC (Volatile Organic Compounds) of flame-retardant corrugated pipes. So, how can we completely solve the odor problem of flame-retardant corrugated pipes? The reason why corrugated pipes have an unpleasant odor is that the raw materials are rather diverse and mixed. The decomposition of small-molecule materials in the raw materials, the additives added to plastic products, or the use of recycled materials will all cause the corrugated pipes to carry odors such as ethylene, hydrogen sulfide, sulfur dioxide, amine, ammonia, or other unpleasant smells. 

In response to this, the screening of resins, the selection of fillers, the combination of processing aids, as well as the molding and post-treatment processes are all matters that require attention. In addition, odor removers can also be added during the processing.
