Ines Dumsch, underlined the high level of innovation in non-halogenated flame retardants, both in research and in applications in user industries such as construction and automotive. Customers are looking for new additives for new polymer applications and to move away from halogenated flame retardants, but performance and price must be comparable. In her opinion, it would be desirable to move towards polymeric flame retardants in order to avoid issues of migration out of polymers (blooming) and to improve polymer compatibility, but with price remaining a key objective. Another issue is that of corrosion in applications such as cables and electronics, in the case of migration of acid-generating molecules out of FR polymers. “Low smoke” products are demanded, but this can raise questions of what this claim means, how it should be tested and of complexity of impacts on smoke emission of combinations of additives: further information is needed.

Lehmann&Voss&Co. was established in 1894 as a trading company in Hamburg and is today a trader and distributor of chemical additives and a producer of masterbatches and compounds, with more than 20 years of experience in developing and supplying non-halogenated flame-retardant masterbatches for customers in different applications. In 2017, Lehmann&Voss&Co. was recognised as a Top Innovator company by Lehmann&Voss&Co with its subsidiaries (LEHVOSS Group) has nearly 600 staff worldwide.
