CablesCamillo Cardelli

Camillo Cardelli, iPOOL Materials Design, Italy, explained that cables in Europe today must undergo the EN 59399 vertical fire test for CPR (Construction Products Regulation), with demanding parameters for flame spread, non-dripping, smoke density, smoke corrosivity and smoke toxicity. He presented results of testing of a range of non-halogenated FR cable compounds (tested as tapes) in the “Mini SBI” (see SUSPI, pinfa Newsletter n°76), a non-regulatory, experimental set-up suitable to compare fire behaviour of different compounds and different raw materials.

Thermal insulationArne Klinkebiel

BASF polyurethane insulation

Arne Klinkebiel, BASF (pinfa member), specialises in polyurethane insulation, and underlines the importance of finding new PIN flame retardant solutions. Challenges include the need to respect demanding customer requirements on material and insulation performance and cost, in different polyurethanes all of which are specific, as well as meeting smoke toxicity specifications.

Ecodek wood-polymer compositesLuis Enriquez

Luis Enriquez, Ecodek (Epwin Group), develops wood-polymer composite materials for exterior applications such as fencing and decking. Fire resistance is not generally required today for such applications, but may be required where they are used on balconies or near to buildings, particularly as external thermal insulation is increasingly present. Fire performance of wood-polymer materials is currently being discussed in CEN 15534.

Circular economyElke Metzsch Zilligen

Elke Metzsch-Zilligen, Fraunhofer LBF, presented initial results of the pinfa – Fraunhofer LBF testing of recyclability of PIN flame retarded polymers, by multiple extrusion and ageing. Tests with polypropyleneand PIN FR piperazine pyrophosphate showed recyclability and conservation of fire performance and some mechanical properties for extrusion at 200°C.

PIN synergists to improve PIN FR performanceKathrin Lehmann

Kathrin Lehmann, Evonik, summarised the advantages of organomodified siloxanes (OMS) as functional PIN synergists. Inclusion of specific functional groups onto the ends or sides or siloxane molecular chains enables either full polymer compatibility, or to ensure that part of the OMS molecule embeds in the polymer whilst part remains outside giving interface properties.


tesa performance adhesivesCai Rong Lim

Cai Rong Lim, tesa, is developing new performance adhesive solutions for industrial and professional customers as well as end consumers. Applications are developed for industrial sectors such as automotive, electronics, printing and paper, and building supplies.

Inorganic flame retardant developmentsDesseix PolyOne

Maryline Desseix, Polyone (pinfa member), presented development and testing of innovative solutions to combine PIN flame retardant performance in polymers with sustainability. Inorganic PIN FRs, such as ATH (aluminium trihydrate) and MDH (magnesium hydroxide) offer positive health and environment profiles, and are water soluble, which ensures that they are not bioaccumulative.

High performance PIN FR masterbatchesHannah

Mark Hannah, Gabriel-Chemie, underlines the need for stringent fire safety regulation or specifications to move the market. High fire performance masterbatches are today available, but at a cost. A good example is the sports stadium seating market, where stringent FIFA standards for fire safety of seats and installations mean that we can successfully offer state-of the art flame retardant solutions.

Innovative PIN FR systemJan Pleun Lens

Jan-Pleun Lens, FRX Polymers (pinfa member), presented new applications of the company’s phosphonate PIN FR technologies, available as polymers, oligomers with tailored functional end-groups, and polycarbonate co-polymers. Developing applications include in polyesters (film and fibres, including synthetic hair)), polycarbonates, thermoplastic polyurethanes, and thermosets like epoxies and polyurethanes 

pinfa President, Adrian Beard, Clariant,CREPIM report cover

noted that pinfa is not “campaigning” for the introduction of smoke toxicity requirements in regulation. In the current reassessment of the EU Construction Products Regulation, pinfa has submitted that “the EU should also continue to develop harmonised fire safety, smoke and sustainability standards to address the risks of modern constructions and the challenges of the circular economy” without referring to “toxicity” (see pinfa Newsletter n°84).
