Zinc borate and magnesium hydroxide reduce smoke

Synergistic action of zinc borate or magnesium hydroxide with phosphorus were demonstrated in novel PIN FR coatings applied to 4mm plywood board (up to 75x75 cm, tunnel, cabinet tests, cone calorimeter and smoke density tests). A cyclic phosphate ester was reacted with zinc borate or with magnesium hydroxide, then incorporated into an amino resin, then brush applied to the plywood, with several applications to result in a 0.4 mm coating. Different levels of minerals were tested (0 – 7% by mass).

STPP and pomegranate FR for cotton

In laboratory tests, 3% STPP ‘(sodium tri poly phosphate, the mineral phosphate salt widely used last century in detergents) and pomegranate rind extract were tested as a “green” PIN flame retardant treatment for cotton (150 g/mm2 woven fabric). The extract was obtained by high temperature boiling in water of chopped waste pomegranate rinds.

Mineral functionalised LDHs as PIN FRs for epoxy

Functionalised layered double hydroxide (LDH) were synthesised in a one-step reaction by mixing a solution of organic compounds (SDBS sodium dodecylbenzenesulfonate, sCD hydroxypropyl-sulfobutyl-beta-cyclodextrin and taurine) with solutions of magnesium nitrate Mg(NO3)2 and aluminium nitrate Al(NO3)3 and adjusting pH, then filtering and drying the resulting slurry.

Renewable cellulose and clay for FR coating

Researchers have tested layer-by-layer deposition (LbL) coating on PET film and on polyurethane foam (not specified), alternating cellulose nano-fibrils and clay. The cellulose nano-fibrils were extracted from pulp fibres, then cationised. These fibrils are expected to show good mechanical properties because of crystallinity.

Struvite for PIN flame retardancy of wood

Struvite (magnesium ammonium phosphate) is today recovered from municipal wastewater, food industry waste streams and other wastes. It enables phosphorus recycling as a fertiliser, but has also been tested as a PIN flame retardant for cotton and wood by Yetilmezsoy et al. 2018 (simply placing powdered struvite in or on the material).

UK consultation on building fire safety regulations

he UK Government has launched a public consultation, open to 1st March 2019, on “Document B” (1) of the building regulations. This consultation is a “call for evidence” to inform the review of UK building fire safety, as part of a wider review of fire safety, concerning high rise buildings (following the Hackitt report, see pinfa Newsletter n°92, and the Grenfell Tower fire inquiry) but also “any issues affecting fire safety in all types of building”. The consultation does not however concern specific buildings such as hospitals and schools.

EU FIEP (Fire Information Exchange Platform)

On February 27th 2019, the EU FIEP held its 2nd plenary meeting, bringing together most of the member states representatives, the European Commission, firefighters and stakeholders involved in the 5 project teams identified. The FIEP was launched two years ago, in the aftermath of the Grenfell Tower disaster, to pool knowledge and statistics on fire. Project teams (see pinfa Newsletter n°95) reported on progress and three member states (Sweden, Estonia, Portugal) presented national actions on fire safety.

Compounding World innovations in PIN FRs

The annual feature article in Compounding World on flame retardants illustrates the industry tendency for new developments, featuring only PIN FR solutions, all non-halogenated. The move away from antimony, because of regulatory concerns, is also emphasised. pinfa is cited as identifying new requirements for fire safety in electric vehicles, with demand for non-halogenated FRs resulting from declaration systems such as IMDS and GADS, and in construction and E&E, with demand for low smoke PIN solutions.

Zinc oxide as flame retardant for polypropylene

Zinc oxide (ZnO) has been demonstrated as a PIN flame retardant in a range of materials, including wood, natural fibres and PVA (poly vinyl alcohol) and nano-sized particles of the mineral have shown better dispersion. In this research paper, daisy-shaped zinc oxide nano-wires, diameter 80-120 nm and length 1.5-3 µm, were tested at loadings of 0 – 40 % in polypropylene.

Studies detect phosphorus PIN FRs

Three studies (two USA, one Canada) published in scientific journals have led to media coverage of presence of phosphorus-based flame retardants in different products. One study reports analysis of textiles from 18 children’s car seats (manufactured in the USA, China and Canada) in which two cyclic phosphonates (i), other phosphorus FRs (TDTBPP and RDP (ii)) and the brominated FR DBDPE (iii) were detected at levels indicating deliberate use (PMMMPs 0 – 23 000 µg/g) as well as other brominated FRs at low levels suggesting contamination e.g. from recycled materials.
