Due to the requirements of environmental certification in EU and some large multinational corporates, non-halogenated flame retardant (FR) material is becoming a hot topic while engineering plastics of non-halogen FR performance is the hottest among the hot.
At present, for these non-halogen FR materials used in engineering plastics, such as: PA, PBT, PET, etc. some Chinese companies have developed substitutes similar to the OP series from Clariant AG (for example: OP-1240,OP-1312). While these domestic suppliers have a significant cost advantage the heat resistance property of their products is not stable. As a result, some domestic EP compounders are more cautious when using these domestic alternatives. For the products with more stringent requirements and higher price, they still use imported flame retardants, otherwise, they may use domestic alternatives.
By using halogen free flame retardants, market demand of TPE has increased significantly, however, EBS and oil composed in TPE are not conducive to the FR performance. Also since most products are used in making electric wires (appearance pieces), demands for such auxiliaries are harsh that customers currently focus on high efficient FR performance (adding relatively small addition amount), good resistance to deposit (extraction above 80 degrees), easy fabrication (good thermal resistance and consistently extruded wires), smooth appearance, etc. Currently, Germany Clariant, (OP-935/930), Japan ADEKA, (ADK2200S) and Presafer Phosphorus Chemical Company (EPFR-110T) all offer general grade materials.. Compounders often just add halogen-free FR materials into these general grades to reduce costs or improve performance.
