Sentani Natural Zeolite as a Filler for Polyethylene Composite
at 110oC for 3 hours, dried, crushed using jaw crusher follow with roll crusher. Finally the zeolite was sieved to obtain the grain size of -150 - +200 mesh [11]. The natural zeolite was analyzed using X-ray diffraction (XRD) and Cullity equation to find the degree of crystallinity [12] 2. Composite preparation
