Eurofire Conferences 2013

Eurofire Conferences are unique in that they provide a platform for European issues that directly relate to the work of Fire Safety Engineers. The 2013 event focuses on a wide range of topics from Education Certification, Harnessing New Technologies and facilitating Architectural Trends whilst emphasis continues to maintain focus on Application and Cases Studies. After successful events in both Belgium and France this year’s conference will be host in Switzerland. The location is the charming city of Basel on the borders of France and Germany on
9-10th October.

Influence of oxidation state of phosphorus on the thermal and flammability of polyurea and epoxy resin

This article was published in European Polymer Journal.

Abstract

The focus of this study is an investigation of the effect of oxidation state of phosphorus in phosphorus-based flame retardants on the thermal and flame retardant properties of polyurea and epoxy resin. Three different oxidation states of phosphorus (phosphite, phosphate and phosphine oxide) additives, with different thermal stabilities at a constant phosphorus content (1.5 wt.%) have been utilized. Thermal and flame retardant properties were studied by TGA and cone calorimetry, respectively. The thermal stability of both polymers decreases upon the incorporation of phosphorus flame retardants irrespective of oxidation state and a greater amount of residue was observed in the case of phosphite. Phosphate was found to be better flame retardant in polyurea, whereas phosphite is suitable for epoxy resin. Phosphite will react with epoxy resin by trans-esterification, which is demonstrated by FTIR and 31P NMR. Further, TG–FTIR and XPS studies also provide information on flame retardancy of both polymers with phosphorus flame retardants.

EFRA: In response to a recent study released by the National Institute of Environmental Health Sciences

In response to a recent study released by the National Institute of Environmental Health Sciences(NIEHS) suggesting that certain flame retardants can mimic estrogen, the European Flame Retardant Association (EFRA) issued the following statement:

The crystallographic methodology used in this study, while perhaps offering insight into how estrogen mimicking might occur, provides no evidence that TBBPA, which is known to be quickly metabolized, actually comes in contact with the relevant proteins in the human body. It is unclear why NIEHS chose to use this approach, when the US Environmental Protection Agency has spent many years identifying three tests for estrogenic activity as part of a Congressionally mandated
program for screening substances for potential hormonal activity.
Furthermore, TBBPA went through an 8-year EU Risk Assessment which concluded that TBBPA is safe for use in all its applications and has no significant endocrine potential [1]. This conclusion was also confirmed by the Scientific Committee on Health and Environmental Risks (SCHER). In addition, TBBPA was among the substances examined for its potential role in endocrine disruption as part of an EU project [2] …. Read more: click here

Next event: Workshop-Degradation of fire-retarded polymers in environmental conditions- 24-26 September 2013- Mèze-France

The group “Degradation of organic materials and Fire behavior” of the Chemical Society of France offers a workshop focused on Degradation of fire-retarded polymers in environmental condition in order to :
– give people the basic knowledge in the domains of ageing and fireretardancy
– gather in a two days meeting two different communities with the aim of understanding the impact of environmental ageing of fireretarded polymers on the use properties of the polymeric material
– establish a bond between investigators in the various parts of the fields and to provoke a reflexion on future collaborative programs. The workshop will be organised on the basis of a four half-days meeting. Each session will be devoted to one-two peculiar aspects and will be introduced by general presentations followed by short presentations on recent results.
This workshop could be placed under the auspice of the MoDeSt Society.

An efficient interfacial flame-resistance mode to prepare glass fiber reinforced and flame retarded PA6

This article was published in Journal of Materials Chemistry A , Jul 2013.

Abstract:

The flame retardance of glass fiber reinforced polymers is an important worldwide challenge due to the wick effect caused by glass fiber. In this paper, an interfacial flame resistance mode was proposed in order to solve the problem in an efficient and economic manner. Unlike the conventional bulk flame resistance mode based on a high loading of flame retardants distributed evenly throughout the entire composite matrix, the interfacial flame resistance mode concentrates only a very low content of flame retardants located in the glass fiber–polymer interfacial regions, where the wicking action occurs, grafted on the glass fiber surface. According to this new mode, glass fiber reinforced and flame retarded polyamide 6 was prepared and evaluated. At the combustion temperature, the interaction between the polymer (polyamide 6) and the grafted flame retardant quickly produced inert and rough interfacial chars replacing the original smooth and high-energy surface of the glass fiber. The interfacial char layer could effectively block the adsorption, wetting, spread and flow of the polymer melt on the glass fiber surface, therefore, greatly weakening both the thermodynamic and dynamic processes that induce the wicking action. In addition, the formation of organic side chains on the glass fiber surface by the graft reaction also contributed to an improvement in the interfacial compatibility, favoring enhanced mechanical properties of the composites. The interfacial flame resistance mode provided a novel means for preparing advanced flame retardant glass fiber reinforced polymers.
