• Halogen-free harshen retardants: Bi ƙa'idodin muhalli kuma wakiltar yanayin gaba.

Takaitawa

Ƙirar ƙira ta masu riƙe harshen wuta don XPS yakamata ta dogara ne akan takamaiman yanayin aikace-aikacen da buƙatun tsari, zaɓi tsakanin masu riƙe harshen wuta marasa halogen ko halogen. Halogenated harshen retardants yana ba da babban inganci amma yana haifar da damuwa na muhalli, yayin da masu kare harshen wuta marasa halogen sun fi abokantaka da muhalli amma suna buƙatar ƙarin ƙari. Ta hanyar inganta ƙirar ƙira da matakai, babban aiki, abokantaka na yanayi, da tsada mai tsadar wuta mai kashe wuta XPS za a iya samar da su don saduwa da buƙatun rufin gini da sauran fannoni.
