Low-smoke, halogen-free polyolefin cable
Benvic, a world leader in PVC compounds, has launched HFFR polyolefin cables for construction and electrical industries. The new LINKFLEX HF compounds for cables and sheathing ensure compliance with the EU Construction Product Regulations (CPR) EN 50575 Eca up to B2ca, with low droplets, using PIN flame retardants in a polyolefin matrix to ensure low smoke properties, IEC 60754-2 low acidity emissions.
READ MOREWAPOL: PIN FRs from waste materials
EU project develops PIN FR compounds using waste incineration ash and nitrogen FRs for PP, PA (polypropylene, polyamide). The Horizon 2020 (EIT Raw Materials) project, WAPOL, is developing flame retarded polymers for the automotive industries using PIN FRs from waste materials. PP filled with 20-30% municipal waste incineration ash (treated bottom ash) achieved UL94HB @ 1.6 mm with mechanical properties similar to those of PP-T20.

Polymer Compounders Ltd (PCL) new polycarbonate blend compounds show excellent properties and low toxicity. Established in 1993, PCL specialises in engineering thermoplastics. Their new PC/ABS* and PC/ASA* blends claim better melt processing, lower density and physical properties as good as halogen FR compounds, but use reactive non-halogenated FR polymer formulations to ensure a favourable toxicity profile, no antimony, no FR migration and no bioaccumulation.
READ MOREMetal alginates as PIN flame retardants
Alginates loaded with metal ions can provide effective bio-based PIN FRs for textiles, polymers, surface coatings …. Tens of thousands of tonnes of alginates are produced worldwide annually from brown algae, providing relatively low-cost bio-based materials which are not competing with food crops.
READ MOREBio-based PIN FR for cotton
The natural molecule polylysine, reacted with phosphoric acid, provides a durable PIN FR for cotton fabrics. The polypeptide ε polylysine can be produced by natural fermentation or by a condensation reaction of the biological amino acid lysine, and is used as a food additive.
READ MORE“Green” synthesis of PIN FR for bioplastic
Researchers propose solvent-free synthesis of polymeric phosphorus FR for poly(lactic acid) bioplastic (PLA). The bio-based and biodegradable polymer poly(lactic acid) is highly flammable. Phosphoramides have shown to be effective PIN FRs for PLA at low loadings, but their synthesis relies on organic solvents.
READ MOREDouble FR functionality of phosphorus
An experimental P-based PIN FR for rigid polyurethane foam shows both gas phase and solid phase fire inhibition effects. Researchers synthesised (in two steps) a bi-functional, reactive phosphorus flame retardant for rigid polyurethane foam: PDEP, containing a DOPO and a phosphate (DEP, derived from diethyl phosphite).
READ MOREN-P-Si FR for epoxy
Experimental reactive PIN FR improves mechanical and fire performance of epoxy resin. DOPO (phosphorus) and triethylamine (nitrogen) were reacted with silane (silicon) to generate an N-P-phenylsiloxane macromolecule (PD-PPD) which could be reacted into DGEBA epoxy resin.
