A study of the University of Lille, France, and the transformation of materials research department (Unité Matériaux et Transformations, UMET) carried out show that the use of halogen-free flame retardants Clariant Exolit AP oyster shells to achieve enhanced polypropylene (PP) and efficient flame. The results showed that the phosphate-based Exolit AP760 added to the high-performance polypropylene composites, can greatly enhance its thermal stability.

"Green" polypropylene composites research and development business "Eurostar Engineering Plastics," the company has been at the forefront of the development and commercialization of flame retardant composites. The company uses oyster shells as a special mineral fillers, in order to avoid an adverse impact on the environment, and the problems of high energy consumption in the standard mining process. In addition, this method can also reduce landfill through recycling. Exolit AP can effectively improve the environmental capacity of the complex: Exolit AP is not toxic, does not accumulate in the environment. It can be biodegradable to degrade to phosphate present in nature. In addition, the lower the amount of the flame retardant additive, smaller effect on mechanical properties.

"The results of the project is to demonstrate the use of bio-based materials feasibility of a major breakthrough in the high flame resistance requirements of high-end applications (such as cars and buildings, construction and other industries)." Research team leader Professor UMET Sophie Duquesne, "said In addition to the oyster shell, we are still actively studying flame retardants such as flax and other plants as filler in polymer flame retardant effect, in order to further explore the more environmentally friendly materials to adapt to increasingly stringent environmental requirements.
