PIN FR synergy in polypropylene

PIN FR synergy in polypropylene

Expandable graphite (EG) enhanced fire performance and reduced smoke with magnesium hydroxide in polypropylene. Polypropylene was tested with 0 – 63% magnesium hydroxide (MH), 9 – 30% EG and  a combination of 4 – 17% EG with MH to a total of 57% PIN FR. Replacing c....

ChatGPT rather likes flame retardants

If asked about flame retardants, ChatGPT says they “can be effective in reducing the risk of fires”. The artificial intelligence large-language motor says that “phosphorus-based flame retardants are generally considered to be safer and less toxic than other types of...
Bio-based PIN FR for cotton textiles

Bio-based PIN FR for cotton textiles

Bio-sourced taurine reacted with phosphorus and nitrogen for a wash-durable PIN flame retardant for cotton-nylon blends. Taurine is a sulphur-containing amino acid derivative, widely found in animals and plants (the name comes from its presence in bull’s bile). It was...
