Bu çalışmada, özellikle yalıtım özelliğinin önemli olduğu alanlarında kullanılan polipropilenin ısıl iletkenlik değerlerini düşürerek yalıtım ve enerji tasarrufuna ilave katkı sağlanması amaçlanmıştır. Bu kapsamda polipropilen içerisine düşük ısıl iletkenlik değerine sahip parçacık şeklindeki borik asit katılarak kompozit malzemeler üretilmiştir. Çalışma kapsamında 0.5 – 2.5% arasında değişen üç farklı orandaki borik asit parçacıkları polipropilen içerisine kütlece ilave edilmiştir. Çift vidalı ekstruder ile hazırlanan kompozit karışımlar daha sonra plastik enjeksiyon yöntemiyle kalıplanarak deney numuneleri üretilmiştir. Üretilen numunelerin ısıl iletkenlik değerleri deneysel olarak ölçülmüş ve elde edilen sonuçlar literatürdeki efektif ısıl iletkenlik modelleri ile karşılaştırılmıştır. Çalışma sonucunda, borik asidin polipropilenin ısı iletim katsayısını düşürücü bir etkiye sahip olduğu görülmüştür.
