A fire retardant is a substance that is used to slow down or stop the spread of fire or reduce its intensity. This is commonly accomplished by chemical reactions that reduce the flammability of fuels or delay their combustion. Fire retardants may also cool the fuel through physical action or endothermic chemical reactions. Fire retardants are available as powder, to be mixed with water, as fire-fighting foams and fire-retardant gels. Fire retardants are also available as coatings or sprays to be applied to an object.

  • مثبط الحريق هي مادة من أجل إبطاء أو تعويق الحرائق، وذلك من خلال تفاعل كيميائي تساعد على الإقلال من الاشتعالية أو الاحتراق. تتوفر المواد المثبطة للحريق على شكل مسحوق أو رغوة أو هلام. (ar)
  • Un retardant est un produit chimique destiné à freiner la propagation des incendies. Ce terme inclut des substances agissant par voie chimique et physique (telles que les émulseurs et les gels ignifuges). Les retardateurs de feu peuvent également être des revêtements appliqués à un objet sous forme de spray. (fr)
  • Il liquido ritardante è una sostanza che serve a rallentare e a prevenire processi di combustione. Sostanze di questo tipo vengono tipicamente utilizzate per contrastare incendi di grandi dimensioni. Per comprendere a pieno l'importanza di queste sostanze, sia dal punto di vista economico per l'industria chimica, che per la loro utilità nel contrastare gli incendi, basti pensare che, nei soli Stati Uniti, più di 400 000 abitazioni subiscono ogni anno danni ingenti provocati dal fuoco per un valore complessivo del danno di non meno di sette miliardi di dollari e che in buona parte di questi interventi i vigili del fuoco utilizzano liquidi ritardanti per contrastare l'espandersi delle fiamme.

  • 방염(防炎)은 화재의 위험이 높은 유기고분자 물질에 난연 처리를 하여 불에 잘 타지 않게 하는 것으로 화재 초기 연소의 확대를 방지하거나 지연시키기 위한 것이다. 방염은 불에 타는 것을 어렵게 하여 화재진압이나 대피를 위한 시간을 확보하기 위한 것이지 불에 타지 않는다는 불연(不燃)의 개념이 아니다. (ko)
  • 阻燃剂是除了水以外,其他所有具有降低燃料的可燃性或延遲燃燒的物質之總稱。阻燃劑通常都是利用化學原理產生作用,但也有少數利用物理方式達到滅火目的的阻燃劑型態,例如可以降低可燃物溫度或阻隔空氣而抑制燃燒的物質。 阻燃劑有很多發射噴灑的方式,最常見的是手持式的滅火器,以固定管線噴灑的建築物用阻燃劑,或甚至在森林火災中以滅火機空投。阻燃剂之所以能够阻燃是由于阻燃剂中含有阻燃元素,能够在燃烧时生成不易燃的物质。通常阻燃元素有氯、溴、磷、氮等。 (zh)
  • Zpomalovač hoření, retardér hoření nebo samozhášecí přísada je látka, která zpomaluje nebo zabraňuje hoření. Zpomalovače hoření se v požární ochraně používají velmi často. Nejčastěji používaným zpomalovačem hoření je voda, avšak termín se většinou používá pro chemické zpomalovače. Může se týkat i ochranné vrstvy na předmětu, například zpomalovače ve spreji, který se používá pro ochranu vánočních stromků proti ohni. (cs)
  • Αντιπυρικές ουσίες (αγγλ. fire retardants), ή επιβραδυντικά φωτιάς, ονομάζονται οι ενώσεις που χρησιμοποιούνται σε φυσικά ή συνθετικά οργανικά υλικά για τη βελτίωση της πυραντοχής τους, δηλ. της αντοχής τους στη φωτιά (fire retardancy). Οι ενώσεις αυτές δύναται να ψύχουν τις , είτε διά φυσικής δράσης ή μέσω ενδοθερμικών χημικών αντιδράσεων. Μπορεί να είναι στη μορφή (powder), ή να γίνονται , ή επίσης να έχουν τη μορφή του . (el)
