The effect of different mineral filler mixtures on dispersion and thermal properties of polymer composites

Öz

In this study, the effects of different mineral filler (CaCO3, talc) mixtures on the dispersion and thermal properties of polymer (PE, PP) were examined. In the compound production carried out in a laboratory-scale twin-screw extruder, granular products were obtained by feeding talc and coated calcite (c-CaCO3) with low-density polyethylene (LDPE), high-density polyethylene (HDPE) and polypropylene (PP) in certain proportions (wt. 30/70). Dispersion and thermal properties of the products were determined by performing MFI, density, TGA, FTIR and microtomography analyzes on the obtained polymer composite products.

Farklı mineral dolgu karışımlarının polimer kompozitlerin dispersiyon ve termal özelliklerine etkisi

Öz

Bu çalışmada, farklı mineral dolgu (CaCO3, talk) karışımlarının polimerin (PE, PP) dispersiyon ve termal özelliklerine etkisi incelenmiştir. Laboratuvar ölçekli çift vidalı ektrüderde yapılan kompaund üretiminde, talk ve kaplı kalsit ile alçak yoğunluklu polietilen (AYPE), yüksek yoğunluklu polietilen (YYPE) ve polipropilen (PP) belirli oranlarda (ağırlıkça 30/70) beslenerek granüle ürünler elde edilmiştir. Elde edilen polimer kompozit ürünler üzerinde MFI, yoğunluk, TGA, FTIR, mikrotomografi analizleri yapılarak ürünlere ait dispersiyon ve termal özellikler tespit edilmiştir.
