PORTAFLAME® SG
PORTAFLAME® SG
PORTAFLAME® SG is produced from carefully selected synthetic aluminium hydroxide (ATH). The chemical composition of raw material and product is closely monitored and particle size is kept within a narrow variation.
The range of PORTAFLAME® SG ground halogen-free flame retardant (HFFR) fillers is used in a broad range of applications, e.g. ETICS/EIFS, SMC and BMC, carpet backing, potting resins, sealants, adhesives, and polymer concrete. Their flame-retarding action is based mainly upon the endothermic decomposition of metal hydroxide (heat-sink effect) and simultaneous release of water vapor. This reaction starts at about 200°C. In addition to flame retardancy, fillers in this product range possess a strong smoke-suppressing ability.
In ETICS/EIFS applications, they are mainly used in the base coat, giving a significant improvement in flame retardancy over other fillers, such as calcium carbonate. By combining coarse and fine PORTAFLAME® SG grades, a better packing is obtained, allowing higher loading levels compared to using a single grade with similar rheological paint properties.
