Polimer esaslı (plastik) malzemelerin 1950’li yıllardan bu yana hayatın
her alanında gittikçe artan bir oranda kullanım alanı bulmaktadır. Polipropilen
(PP), poliolefin grubunda yer alan ve oldukça yaygın kullanılan termoplastik
polimerlerden birisidir. PP’den elde edilen ürünler paketleme ve ambalaj
sektöründe, otomotiv uygulamalarında, elektrik ve elektronik sektöründe ve inşaat
sektöründe çok geniş bir uygulama alanına sahiptir. PP’nin tekstil sektöründe
kullanımı da büyük önem arz etmektedir. PP düşük maliyet, hafiflik, yüksek mekanik
dayanıklılık, yüksek kimyasal direnç ve istenilen ısıl kararlılık gibi önemli
avantajları nedeniyle kullanım alanı sürekli artan bir malzemedir. Yanmaya
karşı direnç PP’nin kullanıldığı pek çok alanda önemlidir. PP yüksek yanıcılığa
sahip olduğundan çeşitli alev geciktirici katkı malzemeleri ile güç tutuşur
hale getirilerek bu alanlarda kullanılır. Bu çalışmada PP’ye güç tutuşurluk özelliği
(alev geciktiricilik) kazandırmak amacıyla kullanılan katkı malzemeleri
incelenmiş, bu alandaki güncel gelişmelere ve gelecekteki beklentilere
değinilmiştir. Güç tutuşurluk özelliği kazandıran malzemeler halojen içerenler,
şişen sistemler, fosfor esaslılar, metal hidroksitler, nano malzemeler ve
silikon içerenler olarak gruplandırılmıştır. Bu çalışmada “güç tutuşurluk” ve
“alev geciktiricilik” terimleri İngilizce “flame retardancy” terimi ile eş
anlamlı olarak kullanılmıştır.
